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.
