Este estudo avaliou a composição da anurofauna, bem como a distribuição espacial e temporal das espécies em quatro poças permanentes em uma região montanhosa do Espírito Santo, sudeste do Brasil. Duas dessas poças são conectadas a fragmentos florestais por corredores florestais e as outras duas poças são circundadas por plantação de eucalipto e habitação humana. Foram registradas 22 espécies, incluídas em cinco famílias, entre dezembro de 2003 a novembro de 2004. Hylidae foi a mais rica e abundante, apresentando elevada sobreposição espacial. Nove espécies foram coletadas em vegetação abaixo de 0,60 m, sendo o sítio de vocalização mais utilizado. Riqueza de espécies e abundância foram maiores em meses chuvosos. Poças com corredores abrigaram maior riqueza de espécies. Adicionalmente quatorze espécies foram exclusivamente encontradas nessas poças. A estrutura da comunidade de anuros em poças permanentes nessa paisagem fragmentada é aparentemente determinada pela presença ou ausência de corredores florestais conectando fragmentos em topos de morro às poças d'água ocorrentes ao longo dos vales.

A remarkable new species of pulmonate land snail was found in the collection of the Senckenberg Forschungninstitut und Naturmuseum Frankfurt (Frankfurt am Main, Germany) and is described here as Leiostracus faerie sp. nov. It can be easily identified by its small and translucent shell with fine axial light brown bands and its protoconch sculpture. It was collected in the Rio Doce ("Doce River") region in Espírito Santo, Brazil, an area known for a high diversity and endemicity of land snails. This discovery shows how little this fauna is known and reinforces the importance of museum collections in the study of biodiversity and conservation.

1. The author suggests a tecnique for the determination of vitamin A on shark liver oils in industrial plants. The advantages of using oly four ml. of reagent and of permitting a quickly rigorous reading by photoeletric cell, contribute to the possibility of the examination of a great number of samples daily; 2. It is described a survey on the vitamin A content of oils from shark livers, which has been made at the Finishing School Darcy Vargas, Marammaia Is., Rio de Janeiro State. The conclusions are the following: a) Male individuals have showed generally tendency for higher vitamin A pontency oils; b) The size of the fish does not interfere in the vitamin content of the oil (graphic 4); c) The data collected upon 3.085 individuals led to the conclusion that some species are richer in the reservated vitamin although it was possible to catch in the same specie fishes with widely variable potency in vitamin A. One fish belonging to the specie C. lamia produced the highest vitamin potency oil with 167.712 international units per gram; d) The fishing season appears to have no influence on the oils; e) The adventitous food seems to be the most important factor affecting the content of vitamin A of the shark-liver oils; 3. The presence and the quantity of vitamin D in those oils was investigated and two of the determinations are presented.

The A. refers that, in his last study, in his last studying trip to Colonia Santa Fé, Minas Gerais State, last month of March (autumn), had captured many wild flies (all from Tachinidae family, according to various entomologists of the Instituto Oswaldo Cruz), on a leprotic ulceration of the left leg of a lepromatous case of leprosy. The microscopical examination of the abdominal material from sch flies proved the presence, in rather great number, of HANSEN bacilli and a fungus of the genus Empusa COHN 1855. The A. intends to continue, next summer, such interesting research.

Os AA. iniciam com o presente trabalho uma série de publicações com o fim de rever as espécies neotropicais da família Simuliidae. Fazem a revisão bibliográfica, a redescrição do macho, fêmea, pupa, larva, e elegem os neótipos de S. (E) orbitale LUTZ, 1910. Descrevem S. (E.) pintoi n. sp. de macho, fêmea, pupa e larva; consideram S. nigrimanum MACQ., 1837 como sp. inquirendae.
