No. 3.— The Stanford Expedition to Brazil, 1911. John C. Branner, 
Director. The Chilopoda of Brazil. 
By Rate V. CHAMBERLIN. 
TuHE 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 localities 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 Zodlogy. 
In Dr. Brélemann’s Catalogue des Myriopodes du Brésil (Sao 
Paulo, 1909. Catalogos de Fauna Braziliera, 2, issued by the Museu 
Paulista), after the elimination of manifest synonyms 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 previously 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
