"Test small, fusiform, often slightly compressed; chambers distinct, 

 inflated; sutures distinct, depressed, slightly oblique; wall ornamented 

 by numerous fine costae, as many as ten to a chamber, those of each 

 chamber independent of adjacent ones, last-formed chambers somewhat 

 smooth; aperture terminal, small, with a short neck. Length 0.60-0.70 

 mm; diameter 0.30-0.40 mm." 



The original description is quoted above, of this species from the 

 Miocene of California. A number of specimens from the following sta- 

 tions: 1, 2, 57, 227, 509, 1077, 1081, 1123, 1125, 1146, 1190, 1225, 

 1226, 2155, may be" referred here, making the first Recent records for 

 this species. These Recent specimens differ somewhat, chiefly in being 

 proportionately slenderer. 



Distribution. — The records here off San Pedro, and the Channel 

 Islands, indicate a depth range of 12 to 170 fms; off Guadalupe and San 

 Benito Islands, 35 to 200 fms; and 17 to 25 fms in San Jose Del Cabo 

 Bay.

Test small, compressed in the later portion, tending to become uni- 

 serial, greatest breadth usually at about the lower third; chambers dis- 

 tinct, slightly inflated, rather high, slightly overhanging earlier ones; 

 sutures distinct, deeply incised, curved; wall thin, translucent, orna- 

 mented by numerous low, straight, narrow costae, about 8 or 10 to a 

 chamber, not continuous across the sutures, ending in slight, backwardly- 

 projecting spines; aperture at the end of a short, broad neck, surrounded 

 by a narrow, phialine lip.
