mella only slightly curved; umbilicus narrow and like that of 
G. coxi Angas (Verco MS). Holotype, height 3 diam. 3.3 mm. 
Locality, Gulf St. \ incent, with two paratypes. (Reg. No. 
D 1 1435 S.A. Mus.) A species quite distinct from any other 
Australian form. Sir Joseph Verco had four examples (now in 
the S.A. Museum) labelled “corallina sp. nov./’ together with 
his description as above; also noting that he had received the 
shells from Dr. Basedow, locality, Gulf St. Vincent. It is not 
stated whether they were beach gathered or dredged. We 
Lave no other records and would like to hear from collectors 
who have taken it.
