Test elongate, slender, curved, basal end extending out into a distinct 

 point, apertural end with an elongate, tapering neck and a slightly den- 

 tate lip, middle portion with the sides nearly parallel ; wall smooth, thin, 

 and translucent. Length up to 3 mm. ; diameter up to 0.2 mm. 



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

 near San Pedro, California, and it has not been recorded elsewhere.

 1241, 1242, 207, 269, 2035, 2036, and 312. 



Distribution. — One record, Station Or. 10, is oH the coast of Oregon 

 in 26 to 58 fms. Stations 84 through 1242 are all in the waters of the 

 Channel Islands with a depth range of 10 to 340 fms., the average being 

 80 fms. Stations 2035 and 2036 extend the range southward into the 

 Gulf of California at Angel de la Guardia Island in 46 to 75 fms. Sta- 

 tion 312 places it off Panama in 14 fms. At present a greater abundance 

 of these forms has been found off Santa Rosa, Santa Cruz, and Catalina 

 Islands in 42 and 132 fms. respectively.

 Plate 44, Fig. 12 



From the records this is a very variable species. It is elongate with a 

 long spinose initial end and the apertural end with an elongate, slender 

 neck, the main body of the test elongate with the sides nearly parallel in 

 the middle, and the surface with numerous very fine longitudinal costae. 



Stations: A-2, A-16, 80, 1005, 1006, 1068, 1083, 1102, 1103, 1123, 

 1158, 1161, 1192, 1200, 1201, 1203, 1204, 1206, 1215, 1216, 1218, 1220,

 607, and 613. 



Distribution. — With the exception of the A-2 Station off Wrangell, 

 Alaska, Stations 84-1242 are off the Channel Islands. The range in 

 depth is 7 to 285 fms. with the average being 70 fms. Station 2070 places 

 this species as far south as Guadalupe Island in 250 fms. Stations 607 

 and 613 are in European waters. The number of specimens seemed to 

 vary greatly ; the best records are for Wrangell, Alaska.
