NO, 6 CUSHMAN, MCCULLOCH : LAGENIDAE 341 



Lagena inepta Cushman and McCulloch, new species 

 Plate 45, Figs. 11-13 



Test small, having the main body globular or slightly longer than 

 broad, basal end broadly rounded, apertural end extended into a short, 

 almost cylindrical, neck with a slight lip; wall ornamented with raised 

 costae sometimes elongate toward the apertural end but usually making 

 up a very irregular polj^gonal pattern. Length 0.25-0.30 mm. ; diameter 

 0.15-0.20 mm. 



Holotype (AHF no. 71 ) from Station 215. 



This species differs from Entosolenia squamosa (Montagu) in its 

 very definite neck, irregular surface ornamentation, and lack of an in- 

 ternal tube. It somewhat resembles L. curvilineata Balkwill and Wright 

 but differs in its more globular test and more definitely polygonal orna- 

 mentation. 



Stations: 202, 205, 215, 514, and 557. 



Distribution. — ^The type locality is Tangola-Tangola, Mexico, in 15- 

 20 fms. where it occurred in greater abundance. Other stations are ofi 

 Mexico and South America in shallow waters with a depth range of 8 

 to 29 fms. 



Lagena laevis (Montagu) 

 Plate 45, Figs. 14-16 



Many forms have been assigned to this species. Those here figured 

 seem closely related to L. perlucida (Montagu) but lack the costae at 

 the base. Specimens vary considerably in the relative length of the main 

 body of the test. 



Stations: Or. 7, Or. 9, 83, 1015, 1099, 1102, 1121, 1125, 1128, 1135, 

 1136, 1142, 1149, 1168, 1194, 1199, 1212, 1215, 1246, 218, 2070, 2135, 

 2162, 410, 458, 466, 474, 511, 514, 542, 543, 546, 629, and 660. 



Distribution. — In addition to the two records off the coast of Oregon, 

 Stations 83 through 1246 are off the Channel Islands with a depth range 

 of 17 to 490 fms., with an average being 82 fms. Stations 218 through 

 2162 are off the coast of Mexico with a depth average of 113 fms. Sta- 

 tions 410-474 are off Galapagos Islands with a range from 9 to 175 fms., 

 the average being 52 fms. Stations 511-546, off South America, have an 

 average depth of 40 fms. Some specimens collected at Singapore in shal- 

 low water were placed in this species also.
