•^Q^ 3__ The Stanford Expedition to Brazil, 1911. John C. Branner, 

 Director. The Chilopoda of Brazil 



By Ralph V. Chamberlin. 



The Brazilian chilopods upon a study of which the present paper is 

 primarily a report, were collected for the most part by Mr. W. M. 

 Mann as a member of the Stanford expedition to Brazil from June to 

 September, 1911. As indicated hereafter, in the list by locahties and 

 under the particular species concerned, he was assisted in certain 

 localities by Prof. Harold Heath and in others by Dr. Fred Baker. 

 The collection was made almost wholly in parts of Brazil from which 

 either few or no chilopods whatsoever have been previously recorded; 

 and its study, in connection with that of some other material from the 

 country, has brought about such a relatively material increase in the 

 known fauna, that it has seemed advisable to give a complete review 

 of the chilopods of Brazil. The Stanford Expedition collection has 

 been purchased by the Museum of Comparative Zoology. 



In Dr. Brolemann's Catalogue des Myriopodes du Brtsil (Sao 

 Paulo, 1909. Catalogos de Fauna Braziliera, 2, issued by the Museu 

 Paulista), after the elimination of manifest synonjTns and nomina 

 nuda, there are mentioned sixteen genera and thirty-nine species of 

 chilopods. The present paper lists seventy-one species under twenty- 

 five genera. Of the additional forms, two families, three genera, 

 and nineteen species have not been elsewhere recorded as occurring in 

 Brazil, and of these one genus and seventeen species are described as 

 new. In addition it has been deemed advisable to include descrip- 

 tions of a new genus and three new species from the adjoining country 

 of British Guiana, these having been studied in connection with the 

 Brazilian material. 



The following list shows the known geographical distribution of 

 the species. From states not here listed no records have been pub- 

 lished. The new forms, and those new to the Brazilian fauna, are 

 starred. In addition to these, because of the new territory covered, 

 nearly all of the records of species secured by the Expedition are new 

 within Brazil and of interest and importance in throwing light upon 

 distribution. The greater part of pre\dously published records have 

 been from the coastal states from Bahia southward, the most being 

 from Bahia, Rio de Janeiro, and Sao Paulo. The States in which 

 Mr. Mann and his associates worked are listed first and in order
