NO. 5 CUSHMAN AND MCCULLOCH : SOME BULIMINIDAE 245 



Variety differing from the typical in having much heavier, blunter 

 spines that are the continuation of rather indistinct, short costae not 

 projecting as far as in the typical form. 



The types are from the Pliocene of California. 



Specimens from Station 1150 in 47 fathoms, 34° 00' 20'' N.; 119° 

 or 20" W., I0}i miles vilest of Point Dume, southern California, seem 

 identical.

Test two or more times as long as broad, made up of as many as seven 

 whorls, megalospheric form fusiform, microspheric form tapering from 

 the broadest part near the apertural end, initial end occasionally with a 

 small basal spine; chambers distinct, earlier ones not inflated, becoming 

 som.ewhat inflated in the later ones, undercut at the margins ; sutures 

 distinct, slightly depressed in the later portion ; wall mostly smooth except 

 the margins of the undercut chambers which are slightly and irregularly 

 toothed ; aperture loop-shaped, near the apex of the test. Length 0.35- 

 0.55 mm; breadth 0.18-0.28 mm. 



The types are from the Pliocene of California and it is recorded also 

 from the Pleistocene of Lomita Quariy, Palos Verdes Hills, Los Angeles 

 Co., California, and in the present ocean off La Jolla, California. It is 

 not surprising therefore to find this to be common in our material.
