While all species of the genus Callinectes Stimpson, 1860 have a continuous distribution on the Atlantic coast of the Americas, Callinectes sapidus Rathbun, 1896 is the only one with disjunct distribution. Considering that this species was introduced in Europe and Japan, it has been suggested that the occurrence of C. sapidus on the southern coast of Brazil was due to the transport by ballast water. In the archaeological site Ariano Souza, located in the estuary of the Patos Lagoon (southern Brazil), remains of crustaceans, including claws of approximately two thousand years ago, were found. A preliminary analysis of this material showed Callinectes chelae. Because this archaeological site is located inside the estuary, it has been hypothesized that these chelae belong either to C. sapidus or to C. danae Smith, 1869. A comparison between pincers collected in the archaeological and pincers of these two species (90 dactyls, 30 of each type) was performed. The analysis (ANOVA) considered the variability of seven characters of the dactyls, and demonstrated the existence of two groups. Results showed that the measured characters suffice to separate these species, and indicated that the material found in the archaeological site belongs to C. sapidus. The hypothesis of the introduction of C. sapidus in the area is rejected. The possible biogeographic history of the species is discussed.

The A. prepared five antigens from his leprosy cultures which by analogy with ROST's product he called Leprolins. The methods of its preparation and use are given. After a few tests to prove its innocuity for man the A. in cooperation with Dr. JOSÉ MARIANO, injected all five antigens intracutaneously in 120 patients. Now the products are being tested in 17 Leper Colonies of Brazil, in Argentina by Dr. SALOMON SCHUJMAN and in two leprosaria of Colombia. As antigen for skin tests the first results obtained are more or less identical with the results with Lepromin. Its use in serology for leprosy diagnosis will be made by Dr. T. PINTO of Rio, and Prof. LUIZ PRADO BARRIENTOS, of La Paz, Bolivia. As curative means the Leprolins are being injected into resistent lesions of leprosy and also by intraven injections, whose results Dr. José Mariano will publish soon. The Leprolins Souza-Araujo are put at disposal of all leprologists interested in its use.

Em 20 portadores de Lepra, internados na Colônia de São Roque, Paraná, 13 dos quais eram da forma lepromatosa e os 7 restantes da forma nervosa pura ou tuberculoide, o autor estudou a reação intradérmica de antigenos bacilares (Leprolinas Souza-Araujo 1, 1a, 3, 5, 5a), comparativamente com as reações produzidas, ao mesmo tempo, com antígeno lepromatoso (Emulsão de lepromas, lepromina). Observou o seguinte: 1.° - Que a lepromina, comportou-se como habitualmente, isto é, negativa nos lepromatosos e ositiva nos nervosos e tuberculoides e sempre mais intensa ao fim da quarta semana. 2.° - Que as leprolinas provocam reações, que o autor não conclui serem positivas ou negativas no sentido imunológico da expressão em virtude de estar estudando-as neste sentido, nos leprotomatosos e tuberculoides, mas, sempre mais intensas entre a 1.ª e 2.ª semanas, diminuindo de intensidade na 3.ª e desaparecendo ou quase desaparecendo ao fim da quarta semana: nódulos, nódulos-eritema, ulcerações. 3.° - Que nestas reações houve destruição de tecidos, pois a presença tardia de cicatrizes, mesmo quando não houve ulceração, mostra êste fato. 4.° - Que as inoculações das lepromina, não trouxeram nenhum inconveniente a saúde dos paciente; embora um deles tenha apresentado nos primeiros dias leve reação geral; outro, intensa fusão de suas lesões nodulars de lepra e, dois outros, a chamada Reação leprótica.

The A. remembers the history of his lepra-culture and the method he uses to prepare with it the antigen called Leprolin Souza-Araujo, giving photographic illustrations upon the subject. The A. says that the results published about the general action of his Leprolin in leprosy must be revised or rectificated. But he says that the rapid action of his antigen upon perforant ulcers in lepers is consecrated by a large experience. He cured, in relatively short time, perforant ulcers in five lepers. Dr. CASSIANO, from Baurú leper Colony (S. Paulo) treated 21 such cases. The median time of treatment was 23 days and the median dosage of Leprolin injected in each patient was 7.7 cm3. All lesions were cured. After 18 months observation three cases relapsed and 18 (or 85.7%) remained cured. Dr. CALDEIRA, Director of padre DAMIEN Leper Colony (Ubá, Minas Gerais) treated regularly with Leprolin 50 cases of severe perforant ulcers and obtained cure in 46 (or 92%). ina special meeting held in Minas Gerais nineteen leprologists examined the cases of Dr. CALDEIRA and considered the results he have obtained as "magnifico", in the sense as "unic". This experiment is being continued in various brazilian leper colonies and the Author offers, graciously, his antigen to be tried also in foreing countries.

The A. summarizes clinical records of four lepers treated with Leprolin “Souza-Araujo”, as follow: ist – Male, 28 years old, lepromatous case, treated during about 3 years, who received 80 injections of the antigen, being 52 by vene, 18 by muscle and 10 intradermally. Total about 100 cm³. Results: Absence of clinical signs, routine examinations negative for acidfast bacilli. Histopathology: from lepromatous became incaracteristic, with a few bacilli. Mitsuda test from negative became positive. 2nd – Male, 33 ys. old, lepromatous case. From September 1944 to February 1948 received 110 intravenous injections (57 cm³) and 10 cm³ perineurally to control neurites. His Mitsuda test was negative in 1944 and in 1945 became positive and remained so until 1948 (4 times controlled). Since Sept. 1946 became bacillus negative in his mucous, ear lobe and lymph nodes. Out of his lepromatous symptoms remained only mild atrophy of his hands. 3rd- Male, 30 ys. old, lepromatous case, treated since 1944. From 1946 to Feb. 1948 received 80 intravenous injections (high dosage: from 2 to 5 cm³), total 310 cm³ and 140 cm³ intramuscularly. His Mitsuda test was negative in 1943; became positive (from 1945 till 1948) after Leprolin treatment. Bacilloscopy became negative even in sections. Histopathology: the lesions from lepromatous changed to tuberculoid. 4th – Male, 17 years old, lepromatous case, received, from Dec. 1944 to Feb. 1948 only 88 intravenous injections of small doses of Leprolin (0,1 to 1,0 cm³). His Mitsuda remained negative from 1944 to 1946 and in 1947 became positive. Routine examinations negative for bacilli. Histopathology: the lepromataus lesions regressed to incaracteristic, without bacillus.

The writer, as medical director of Father Damien Leper Colony (Ubá, Minas Gerais, Brasil), treated 50 cases of perforating ulcers, from 2 to 40 years of duration, using the antigens prepared with acid-fast bacilli cultures obtained from leprous material by Dr. H. C. de Souza-Araujo. Dosage from 0,12 to 39,35 cm3, injected inside the ulcers, intramuscularly, every 2 to 4 days, accordingly to the patient reaction some of them presenting fever until 41° Centigrade. The result was cicatrization of the ulcers in 92% (46 out of 50) of the patients. The author concluded that the majority of his patients tolerate perfectly the medicine and that its efect was very eficient.

São descritos o macho e a fêmea de uma nova espécie de flebotomíneo - Lutzomyia ramirezi sp. n. - coletada em fenda de rocha em Grão Mogol, Estado de Minas Gerais, Brasil. O macho é caracterizado por apresentar o dististilo com 5 espinhos e o parámero ramificado. A fêmea assemelha-se superficialmente às fêmeas do subgênero Lutzomyia s. str. porém, apresenta ascóides muito curtos e espinhos extremamente pequenos na parte posterior do faringe. A nova espécie é incluída no grupo das espécies "aberrantes ou isoladas" de acordo com Martins, Williams & Falcão, 1978. É também descrita a fêmea de Lutzomyia (Lutzomyia) alencari martins, Souza e Falcão, 1962, coletada na mesma região.
