Pacific Shores of North America. 5 



The Smithsonian Institution has with its usual liberality- 

 allowed me the use of the very numerous specimens m its 

 museum, obtained mostly through the researches of Lieut. 

 Trowbridge, Drs. Suckle v and Newberry, and Mr. A. S. 

 Taylor. These specimens, together with those found by 

 myself while on the North Pacific Exploring Expedition, 

 form a large addition to Mr. Samuels's collection, and have 

 enabled me to make more extended and satisfactory obser- 

 vations upon these divisions of our Western Fauna. 



It will be seen that more than one hundred and thirty 

 species of the class Crustacea have been determined to
