140 H. Rathbun — List of the Brazilian Echinoderms. 



the lists of species. I am to be held responsible only for the identi- 

 fioation of the species collected by the (xeologicul 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 fonnd 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. Yerrill, for the use of valuable specimens 

 and books, and for much aid and advice, enabling me to better pei*- 

 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.
