Notice of the Crustacea collected by Prof. C. F. Hartt 

 ON the coast of Brazil in 1867. By Sid^^ey I. Smith. 



Read, May 19th, 1869. 



Ix the first volume of these Transactions, Prof. Verrill has noticed 

 the Radiata of the collection made by Prof Hartt upon the coast of 

 Brazil during the summer of 1867, and the Crustacea of the same col- 

 lection, having been submitted to me for examination, was found to 

 contain so many species new to the Brazilian fauna that the publica- 

 tion of the following list seemed desirable. 



The collection, although quite small in number of specimens and 

 representing only the higher groups of the class, is interesting from 

 the large proportion which it contains of species heretofore known 

 only from the West Indies or Flordia. This is, perhaps, due chiefly 

 to the fact that most of the collections brought from Brazil have been 

 made at Rio de Janeiro where there are no coral reefs, while Prof 

 Hartt's collection was made principally on the rocky and reef-bearing 

 parts of the coast.
