Vol. VI] EVERMANN— DIRECTOR'S REPORT FOR 1916 255 



Department of Invertebrate Zoology 

 By Walter K. Fisher, Curator 



Since the Department of Invertebrate Zoology is in a formative stage 

 the work for the year has emphasized the accumulation of a collection. 



Systematic collecting was conducted at three points along the California 

 coast : 



1. By the curator, at Monterey Bay and vicinity, during June. 



2. By Mr. Carl Hubbs, in the region of Point Conception, during June. 



3. By several members of the Department of Biology, University of 

 Southern California, during a two-weeks' cruise of their dredging boat 

 about Santa Catalina Island. 



These have resulted in the accumulation of a considerable amount of 

 material, which is being sorted. 



In addition, the curator secured from Mr. W. F. Thompson of Stanford 

 University a very valuable collection of west coast Gephyrean worms, as 

 well as a miscellaneous collection of invertebrates taken in British Colum- 

 bia and along the coast of California. 



A small collection of Southern California echinoderms was donated by 

 the University of Southern California. 



A representative series of invertebrates was collected in the vicinity of 

 Hilo, Hawaii, by Miss Leslie Tulloch, and after her untimely death was 

 sent to the Academy by Miss Martha Tulloch. 



Prof. Frank W. Weymouth, of Stanford University, has contributed a 

 small lot of echinoderms and crustacea from Boundary Bay, B. C.

 field work this year, the department has been able to accomphsh much 

 very desirable exploration and investigations in three different portions of 

 California. Laboratory studies on the Oligocene of Washington and Cali- 

 fornia, the Miocene of the Mexican Gulf Coast, the Caribbean, Panama and 

 Lower California, the Pleistocene and Pliocene of Sonoma County, the 

 Martinez-Eocene of the Rock Creek Quadrangle in Southern California, 

 the Eocene of Mexico have been completed or are in progress. Some ex- 

 hibit material has been arranged and more is in course of preparation for 

 exhibition in the Museum. 



care of collections 



The paleontological collections are practically all numbered with locality 

 number, and the types, cotypes and figured forms given catalogue numbers
