NO. 12 STRONG AND HERTLEIN : MARINE MOLLUSKS 201 



Holotype: No. 751 (Calif. Acad. Sci. Paleo. Type Coll.), from 

 Loc. 27,229 (C.A.S.), dredged in from 3 to 9 fms. in Bahia Honda, 

 Panama. L. G. Hertlein collector. Four additional specimens were 

 dredged at the same locality. 



In the key given by Dall & Bartsch to the west coast species in the 

 subgenus Fyrgiscus,^"^ this would follow indentata, a species described 

 from the Gulf of California, which it resembles. It differs from that 

 species in having the tabulation on the ribs only, as well as in other 

 details. 



This species is named for Dr. Colin H. Crickmay, formerly Assist- 

 ant Professor of Paleontology at the University of California at Los 

 Angeles, in recognition of his contributions to the Paleontology of 

 western North America.
