28 PROCEEDINGS OF THE ACADEMY OF [1899. 



Cassiu had the original Peale collectiou submitted to him upon 

 which to prepare his report. These specimens were mainly 

 returned to the National Museum, but a small number, including 

 some types, were presented to the Academy. Peale' s work is 

 remarkable for the number of names it adds to the synonymy, for 

 out of 109 species described as new, only thirty-three are accepted 

 in Cassin's edition. The few novelties described by Cassin from 

 the collection are originally described in the Academy Proceedings. 



Cassin's types have been grouped geographically in the following 

 list and all the species proposed by him are included whether the 

 types are in the Academy or not.
