This species upon comparison with the type, seems very close to this 

 species described and previously known only from the Miocene of Cali- 

 fornia. 



Three specimens were recorded from Station 1194. 



Distribution. — The single record is 4^^ miles NW of buoy, Cortes 

 Bank in 110 fms.

"Test fusiform, broadest toward the apertural end, initial end 

 rounded; chambers numerous, inflated; sutures distinct and depressed; 

 wall in the early portion roughened with bristly points, very fine and 

 numerous, not as conspicuous in later chambers except in the sutural 

 regions; apertural end with a short cylindrical neck and slightly flaring 

 lip. Length up to 0.85 mm." 



The bristly ornamentation occasionally develops into actual fine spines 

 on the initial portion of the test and may be longitudinally aligned. Our 

 specimens are generally smaller but some tend to be more robust than the 

 types. Several are figured to illustrate the variations. 



The original description is quoted above. This species was described 

 from 1390 fathoms, off southern California {Guide Sta. 3). It occurs in 

 typical form but never abundantly at a number of stations as follows: 

 A-1, Or. 9, Or. 10, 1, 58, 80, 82, 136, 144, 230, 1074, 1078, 1079, 1100, 

 1101, 1116, 1117, 1119, 1120, 1125, 1132, 1135, 1139, 1143, 1157, 

 1161, 1165, 1168, 1173, 1174, 1175, 1177, 1178. 



Distribution. — In addition to the numerous records off the Channel 

 Islands in 2 to 300 fms, there is a northern record here off Ketchikan, 

 Alaska, in 8 fms and one at Los Frailes, Mexico, in 160 fms.
