Test planispiral, somewhat compressed, excavated in the umbilical 

 region, composed of about three coils, partially involute, periphery 

 broadly rounded, not lobulated ; chambers 8-11 in the last-formed coil, 

 broad and lovi^, sutures slightly if at all depressed; wall arenaceous, 

 firmly cemented, smoothly finished; aperture a simple curved slit at the 

 base of the last-formed chamber. 



There are a very few specimens from locality 82 (or 205) which 

 i'-eem to belong to this species and it has not been noted elsewhere. 



Diameter 0.55 mm. 



Distribution. — Off Catalina near Long Point, from 147 to 215 fms.

Test comparatively small, much compressed, periphery rounded, 

 sides flattened, coils in the adult somewhat evolute, exposing the earlier 

 coils, very slightly umbilicate; chambers very distinct, 8-10 in the adult 

 coil, increasing very gradually in size as added, not greatly inflated ; 

 sutures distinct, slightly depressed, sigmoid ; wall finely arenaceous with 

 a few larger fragments but exterior of the test smooth and polished ; 

 aperture semicircular to elongate at the base of the last-formed chamber 

 in the median line. 



Diameter 0.50-0.65 mm ; thickness 0.20 mm. 



Holotype (AHF no. 8) from Station A-1. 



In some respects this species resembles H. columbiense but is usually 

 smaller, very much more compressed and more evolute. It has occurred 

 at numerous stations, specimens frequently abundant: A-1, 559, 2074,
