292 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 



This species was described from the Dry Tortugas, off Florida, and 

 has been very widely recorded, both Recent and fossil (Pliocene and 

 Miocene). Our specimens have been compared with the types and some 

 are considerably larger, but nevertheless would seem to belong here. 



These specimens strongly resemble A. byramensis (Cushman) from 

 the Oligocene of Mississippi, especially in showing the two forms, one 

 smoothly fusiform and the other greatly indented. That species, however, 

 is more heavily costate throughout. 



They are from the following stations: Or. 7, Or. 10, 73, 76, 80, 82, 

 83, 101, 109, 113, 114, 133, 135, 144, 207, 222, 223, 225, 226, 227, 228,
