Specimens comparable with Duncan's figures, obtained from a 

 soft polyzoal limestone at the mouth of the Onkaparinga, have a 

 fairly well-defined suranal fasciole. The species is very variable 

 in shape, some examples are more depressed than the type, whilst 

 in the opposite direction others are moderately elevated like 

 H. T^^ecensis, Leymerie ; and a few examples are subconic with a 

 proportion of the long diameter to the height of three to two. 



Duncan admits that RhyncJwpygus dyasteroides is a crushed 

 Holaster, and it would have been well if he had added — and
