Distribution. — Station 1151 is one mile NE San Miguel Island 34° 

 05' 05'' N 120° 20' 40" W in 35 fms. Stations 1000-1246 are also of? 

 the Channel Islands, the depth range being 37 to 212 fms. with the 

 average being 65 fms. Stations 215-2168 are off the coast of Mexico with 

 a depth range of 6 to 125 fms., the average being 40 fms. Off Central 

 America, Galapagos Islands and South America, Stations 312-583 show 

 a depth range of 4 to 35 fms.

"Test subglobular to pyriform, broadest toward the base, apertural 

 end tapering to a short slender neck ; wall ornamented with a few high 

 platelike costae, occasionally twisted, coalescing at the upper end and 

 forming a collar made up of a reticulate network below the neck." 



This species evidently is widely distributed in the Recent oceans. It is 

 probably related to forms that have been assigned to L. acuticosta Reuss. 

 In the Hancock material it is quite variable and two unusual forms are 

 figured on our plate. One of these has the costae in a distinct spiral and 

 the other has them bifurcate toward the base. 



Stations: 1010, 1103, 1110, 1117, 1139, 1147, 1167, 1180, 1182, 

 1198, 1205, 1218, 1224, 1226, 1246, and 227. 



Distribution. — Stations 1010 through 1246 all off the Channel Is- 

 lands with a depth range of 10 to 285 fms., with the depth average being 

 75 fms. A single record. Station 227, Guadalupe Island, Mexico, was 

 200 fms. Some of the best material was found off San Diego, California.
