O gênero Micrurus reúne serpentes de hábitos semi-fossoriais, terrestres e semiaquáticos, distribuídas desde o Sul dos Estados Unidos até o Sul da Argentina. Entre as cerca de 66 espécies atualmente válidas, 25 são registradas para a Amazônia brasileira. Com o objetivo de ampliar o conhecimento das serpentes do gênero Micrurus na Amazônia brasileira, foram levantados neste trabalho dados de lepidose, hemipênis e distribuição geográfica de 544 exemplares de 11 espécies. O presente trabalho compreende dois capítulos. O primeiro capítulo apresenta uma descrição comparativa dos hemipênis de 11 espécies de Micrurus. Baseado nos resultados obtidos nas análises dos exemplares foi elaborada diagnose, padrão de desenho e coloração, descrição e representação do hemipênis e mapa de distribuição geográfica para cada táxon. Neste capítulo são apresentadas descrições inéditas dos hemipênis de M. hemprichii ortoni e M. paraensis além de variações morfológicas até então não descritas da morfologia hemipeniana das espécies. O segundo capítulo apresenta uma descrição mais detalhada de duas espécies, M. filiformis e M. paraensis, com base na morfologia externa e do hemipênis.

The manuscripts of Diarium Surinamicum by Daniel Rolander practically remained ignored and unpublished for over 240 years, till the recent publication of its translation into English, which occurred in 2008. In this, the names of species described and/or cited by Rolander were faithfully retained, hence preserving the indication of them without authorship, for the vast majority. In the present work, all the names of plants that were treated by Rolander in his journal, about 664, including by tradition the fungi and algae, are contextualised in relation to the authorship, reference to the publication of the protologue, pagination of citations/descriptions in the manuscripts and in the published translation, indication of probable misidentifications with possible alternative names, vernacular names, and related literature. Additionally, we searched for the vouchers collected by Rolander, scattered in several herbaria, which have been linked to the probable names and descriptions in the diary. Given the considerable time till the publication of these names, and by the lack of indication of their nomenclatural types in the English version, the great majority of the new species described by Rolander, which would have priority if published in due time, became invalid names according to the ICN. Nevertheless, the list of Rolandrian species here presented, from his work that has finally taken a place in the history of natural sciences, shows that he was also a competent botanist, besides being a skilled entomologist, having recognised and detailedly described many of the Surinamese plants hitherto unknown to science.

The purpose of this paper is to show some characteristics and essential information related to the Brazilian periodicals in the 19th century Revista Popular (1859-1862) and Jornal das Famílias (1863-1878), whose owner was the Frenchman Baptiste Louis Garnier. By that time the proliferation of periodicals attracts attention mainly because several of them had ephemeral existence, in opposition to Garnier’s periodicals which as a whole amount to 19 years in circulation. The research on these periodicals becomes relevant since they are well succeeded publications whose study makes possible the widening of the knowledge on social and cultural aspects of a very important period in Brazilian society.

Speocarcinus dentatus n. sp. is described from the southwestern Atlantic. The new species can be easily separated from its congeners by a suite of carapace and appendage characters. Speocarcinus Stimpson, 1859, now includes eight extant species, all from the Atlantic or Pacific coasts of the Americas. Additional characters to further differentiate between S. carolinensis Stimpson, 1859, and S. lobatus Guinot, 1969, and between S. granulimanus Rathbun, 1894, and S. spinicarpus Guinot, 1969 are documented. The lectotype of S. granulimanus is first described and a key to the species of Speocarcinus is provided.
