R. Rathbun — List of the Brazilian JEchinoderms. 
the lists of species. I am to be held responsible only for the identi- 
fication of the species collected by the Geological Commission ; 
beyond this the work is entirely a compilation. To render the list 
more complete and serviceable, there has been added the extra- 
Brazilian range of all species not confined to that coast : where a 
species is widely distributed, the regions inhabited by it are indicated 
only in a general way ; where it has been found at only one or a few 
localities, these are defined. 
In the preparation of this paper, I have been placed under many 
obligations to Prof. A. E. Verrill, for the use of valuable specimens 
and books, and for much aid and advice, enabling me to better per- 
fect my work than I could otherwise have done. To Mr. Theo. 
Lyman I am indebted, for the identification of several of the more 
critical Ophiurans, and for valuable suggestions in making up the list 
of species of that group.

paper, are as follows, arranged alphabetically, according to the
