Shell Ruborbicular, depressed ; spire composed of two and a 

 half moderately prominent whorls ; upper surface with numerous 

 short irregularly undulating ridges in radiating series, spirally 

 striated ; perforations close together near the periphery. 



Its congener, II. ovinoides, M'Coy, has more prominent 

 radiating ridges on the surface, but they are not undulating, 

 and are larger near the distal end than in the middle. It is 

 very closely allied to H. narosoides, however, and the differences 

 arc chiefly made out by means of casts of each species. 



Dimensions. — Maximum diameter of surface 36 mm. ; minimum 

 diameter 29 mm. 



Form, and Loc. — Pliocene: Flemington, near Melbourne.
