In the British Museum are four specimens mounted on a glass 

 slide, presented by D. Cooper and evidently types. These were said 

 to have been picked out of "sand from Van Diemen's Land." One 

 of them is here figured. 



Tenison-Woods, Tate, May, and Gatliff have assumed that A. pel- 

 lucida is a synonym of Marinula patula. But the species proves 

 to be a Leuconopsis, smaller than L. inermis Hedley. After com- 

 parison in the British Museum with all the other members of the 

 genus except L. victories Gatliff, which is absent from that collec- 

 tion, I found L. pellucidus distinct. 



Probably this is the species catalogued by Tate and May as 

 "Ophicardelus minor" from the Tamar Heads.

In the British Museum are five shells, which Mr. E. A. Smith 

 considered to be types, marked, "Laim. sulcata H. & A. Ad., P.Z.S., 

 1854, New Zealand, M.C." This species, in some respects, is like 0. 

 ornatus, but it has a shorter spire, furrowed with spiral grooves, 

 five on the last whorl and three on the penultimate. The shell is 14 

 mm. long, and 8 mm. broad.

 There are, in the British Museum, nine shells of this species, 

 which Mr. E. A. Smith regarded as types, labelled Moreton Bay. 

 These are 13 mm. long, and 7 mm. broad. One of them is here 

 figured. I think that the species extends to New Zealand.
