354 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 



Variety differing from the typical form in having the costae in a 

 distinct spiral. 



It is difficult to determine whether this spirally costate form should 

 be regarded as a variety or a distinct species. In our present material 

 there seems to be intermediate forms which would suggest a varietal stand- 

 ing for this form. Not all the references are given but only the Recent 

 ones that seem to belong here. 



Stations: 214, 2070, and 616. 



Distribution. — Stations 214 and 2070 are off Clarion and Guadalupe 

 Islands in 15 and 250 fms. respectively. Specimens from Station 616, 

 Nole Island, Whit Sunday, Australia, collected at low tide, have been 

 placed here also. The best material was found off Clarion Island in 

 157 fms.

Lagena striatopunctata Parker and Jones, var. tricosta Cushman and 

 Gray, Special Publ. No. 19, Cushman Lab. Foram. Res., 1946, p. 21, 

 pi. 4, fig. 5. 



Variety differing from the typical form in having three prominent 

 raised perforated costae nearly equally placed on the surface of the test. 



The types of this variety are from the Pleistocene of Timms Point, 

 near San Pedro, California. Recent specimens in the Hancock collection 

 have the three prominent perforated costae usually in a somewhat twisted 

 position as shown in our figures and seem to be included under this 

 variety. 



Stations: 258, 2131, and 510. 



Distribution. — Station 258 in the Gulf of California, San Francis- 

 quito Bay in 16 fms.. Station 2131, north of Isla Partida, Mexico, in 

 62-85 fms. and Station 510, San Francisco Bay, Colombia, extend the 

 range southward from San Pedro. The specimens were rare at all of 

 these stations. 



Lagena striatopunctata Parker and Jones, var. 

 Plate 47, Figs. 21, 22 



A few specimens, two of which are figured, are evidently closely re- 

 lated to this species but have the base somewhat truncated and the costae 

 extended backward and slightly projecting. They suggest Lagena plumi- 

 gera H. B. Brady in some characters but seem to belong distinctly within 

 the varietal group of L. striatopunctata.
