rather deep ; whorls 4, convex, last more or less obtusely carinated ; 

 base convex, the striae and granulations gradually becoming fainter ; 

 umbilicus moderate, deep ; aperture lunately-ovate ; peristome simple 

 thin, more or less angular externally, at the columella triangularly 

 dilated above. (Cox.)

I have not seen in any other species the same kind of rugose 

 striation, granulation, and pilosity, the last often obsolete, which 

 seems to be characteristic. Angas speaks of a " large umbilicus," 

 while PfeifFer writes of the same shell "subanguste umbilicata."

Shell conoidly depressed, rather thin, widely and deeply umbili- 

 cated ; spire slightly elevated, widely conical, obtuse ; whorls five, 

 flatly convex, narrowly concavely depressed near the anterior suture, 

 and margined at the suture ; last whorl rounded, rather depressed 

 above, and bluntly angled at the periphery ; posterior to the angula- 

 tion at the periphery the surface is slightly depressed, thence convex 

 to the suture ; base rather abruptly convex ; aperture not descend- 

 ing in front, oblique to the vertical axis, rotundately lunate ; peri- 

 stome simple, thin, disunited ; columella very slightly reflected over 

 the umbilicus. 



The ornamentation consists of coarse, irregular, oblique striations 

 and distant granulations ; the one and a half apical whorls granu- 

 lose only ; under surface striated. Colour of the living shell 

 unknown. (Tate.) 



Alt. 7, greater diam. 14, lesser 12J mill.; alt. of apert. 6 ; diam. 

 of umbilicus 2? mill.

Somewhat intermediate between H. bordaensis and H. evandaleana, 

 having the shape of the former with the sculpture of the latter. 

 It is flatter and has a larger umbilicus than H. evandaleana.
