Notes on New or little known Species of American Can- 

 croid Crustacea. By Sidney I. Smith. 



The following notes were begun as part of a more extended article 

 on the higher Crustacea of the western coast of tropical America, but 

 the delay in bringing together the requisite material and the discov- 

 ery of undescribed forms from the eastern coast, have induced me to 

 publish in this preliminary manner the more interesting of the new or 

 little known species of both coasts. The materials upon which the 

 descriptions are based, unless otherwise indicated, are in the collec- 

 tions of the Museum of Yale College.
