SOME LAGENIDAE IN THE COLLECTIONS OF THE 

 ALLAN HANCOCK FOUNDATION 



Joseph A. Cushman and Irene McCulloch 



The foraminifera included in this paper belong in the family Lagenidae. 

 This is one of the most difficult families in the foraminifera, in respect to 

 applying specific names, as the amount of variation is very great. Also, it 

 is difficult to try to give the synonymy for various species as so many 

 authors have placed such a wide variety of forms under the same name 

 and many of the records are without figures. We have tried to show some 

 of the variations on our plates. Many of the forms previously referred 

 to Lagena belong in the genus Entosolenia which will be taken up at a 

 later time. For ease in finding the various species of Lagena, they have 

 been arranged alphabetically.

This is a large species described from 30-40 fathoms, off White's 

 Landing, Santa Catalina Island, California, and recorded from the 

 Pleistocene of Timms Point, California. A few of the specimens have a 

 tendency to a twisting of the axis as in Darbyella. The specimens very 

 closely resemble Robulus occidentalis (Cushman), var. novangliae (Cush- 

 man) from the colder waters of the Atlantic Coast. Some of the Pacific 

 Coast specimens are large, measuring up to 5 mm. in diameter. 



Stations: 1042, 1070, 1078, 1082, 1096, 1101, 1103, 1104, 1116, 

 1120, 1130, 1135, 1136, 1138, 1139, 1144, 1158, 1159, 1161, 1165, 1167,

 1242, 1244, 1246, 2157, 2161, 2163, 2164, 420, and 534. 



Distribution. — Most of the records are off San Pedro and the Chan- 

 nel Islands in 46 to 285 fms. with an average depth range of only 72 

 fms. Station 420, Darwin Bay, Tower Island, in 100 fms. and Station 

 534 in 18 fms. extended the range to Peru. The greatest abundance 

 of the species was recorded off San Diego in 75 fms.
