2. — Marginella turbinata (Soiverby), 

 Thes. Conch., t. 75, f . 70, p. 385 ; Reeve, loc. cit., t. 22, f . 122. 



A solid, whitish, shining shell, with a short spire, and faintly crenu- 

 lated round the upper part of the whorls. Length, '45 ; breath, '3 inch. 



Washed up. — Cape Northumberland (Tate), Guichen Bay (S?nea- 

 ton), many examples. 



It occurs at Portland, Victoria ; is rare in South Tasmania ( Woods), 

 and has been dredged in Port Jackson (Angus.) The South Australian 

 examples are very much larger than those from .New South Wales, the 

 dimensions of the latter being, length -35, and breadth '2 inch. 



3. — Marginella subbulbosa (new species). 



Shell shining white, rather solid, having much the shape 

 of M. turbinata, but more regularly convex from apex to front ; apex 

 obtuse ; faintly striated transversely. External lip thickened slightly 

 inflected, minutely denticulated within ; columella quadriplicate ; plaits 

 equi-distant, the anterior two the larger. Length, "15 ; breadth, nearly 

 •1 inch. 



Tt has some resemblance to M. Bensoni (Reeve), which has a tripli- 

 cate columella ; and to M . bulbosa (Reeve), agreeing with it in its quadri- 

 plicate columella and denticulated lip, but differing in its more pro- 

 minent spire. 



Washed Up. — Wauraltie, west side of Spencer's Gulf, two 

 examples (Tate). 



4. — Marginella cymbalum (new species). 



Shell shining white, rather solid, ovately - globose, spire 

 immersed ; columella plicate throughout, plicae about 12, the 

 anterior six stout, the rest not so conspicuous ; outer lip thick and 

 smooth. Length, '2 ; breadth, - 14 inch. 



This species belong to the Section Cryptospira, wherein the last 

 whorl is produced over the spire as in the genus Ovulum ; its nearest ally 

 is M.pisum (Reeve), from which it differs in its a little less globose shape, 

 and in having many plaits on the inner lip, there are only four in that 

 species. M. pisum is recorded by Reeve as simply from Australia, but it 

 has recently been catalogued by Mr. Brazier from the north-east coast of 

 the continent. Another Australian Cryptospira is M. ovulum (Sowerby), 

 but its elongately oval form is a distinguishing character ; the Tasmanian 

 species M. minutissima (T. Woods), has a triplicate columella.
