Habitat. — South Australia (Angas). 



Mr Angas refers to this species as abundant in New Zealand as well as in New South Wales and 

 South Australia generally, but v. Martens (loc. cit.) mentions that it is not found there. Gray (Joe. cit.) 

 merely quotes Martyn as authority for attributing it to New Zealand.

 Island, West Indies. 390 fathoms. Pterojjod ooze. 



Shell. — Small, conoidal, high, whorls tumid, base flattened ; colour white, glossy. 

 Sculpture : The whole substance of the shell is faintly marked with remote spiral threads, 

 and the surface is very faintly scratched with closer microscopic strife. The whorls are 

 bluntly angulated in the middle, and the last is so besides at the base below the periphery ; 

 this angulation meets the outer lip. The second and third whorls have two or three 

 strong spiral threads. Longitudinals — there are very many, close, unequal, very oblique, 

 hair-like lines of growth ; of these, the strongest rise in close-set, infrasutural puckerings, 

 which on the third whorl resemble small beads. Colour : there is a glossy, thin, ivory- 

 white calcareous coat over a brilliant pearly-white layer. Epidermis : on the one living 

 specimen there is an excessively thin tenacious brown layer, which may possibly be 

 only an accidental deposit. Spire high, fine-pointed. Apex blunt, the smooth, round, 

 embryonic 1J whorl scarcely projecting. Whorls 6, of rapid increase, tumid, the pen- 

 ultimate especially rising swollen out of the suture ; the base is a little flattened. Suture 

 linear, not impressed, a little coarse, slightly marginated by the up-lap of the succeeding 

 on the preceding whorl and the slight tumidity caused by the infrasutural puckerings. 

 Mouth very oblique, round, with a soft pearly nacre all round. Outer lip very slightly 

 descending, thick, bevelled outwards to a sharp edge. Pillar-lip: there is a broad, 

 thin, hyaline pad spread over the body and connecting the outer lip and the pillar, which 



1 On the plate this is given as " Turbo heteroclitus, nobis."
