 are rounded at their extremities ; lateral lobes reflected on the sides 

 of the shell two-thirds of its length ; foot extending beyond the shell

 crocata Pse., t. c, p. 20. — Sowb., Conch. Icon., f. 23. 



The shell of this species can hardly be distinguished from that of 

 H. crocata ; but the animal differs widely. (Pse.). 



Animal: Cephalic disk large, oblong triangular, entire in front 

 and truncated, bilobed posteriorly and lobes overlapping ; lateral 

 lobes reflected on the sides of the shell during locomotion, covering 

 about one-half of its length, and nearly meeting on the back ; poste- 

 terior lobe covering the spire ; foot subquadrate, extending a short 

 distance beyond the shell posteriorly ; eyes central, immersed, black ; 

 surrounded by white areolae; color of the animal varying from grey 

 to greyish-yellow and in some nearly to black, being closely mottled 

 and freckled with olive or dusky. (Pse.). 



H. PUSiLLA Pease. Unfi(jured. 



Shell small, cylindrically ovate, rather solid, white; surface finely 

 cancellated: apex slightly umbilicated or perforated; aperture nar- 

 row, contracted posteriorly, slight fold at base of columella. (Pse.).
