BiTTiuM ELONGATUM Sowerby. 

 (Plate Ixxxi., fig.54.) 



Cet'ithiuni elongatum Sowerby, Thes. Conch., ii., 1855, p. 878,

Tn the British Museum is a series, apparently the type of this 

 species, labelled " Sydney, under stones, F. Strange." To facili- 

 tate the identification of this, Mr. E. A. Smith kindly allowed 

 me to bring back a specimen, 10 mm. in length, which is here 

 figured. 



Search failed to find any Australian shell at all like B. 

 elongatnm, and, as the Mediterranean is mentioned in the 

 original description, I sought the help of Mr. J. R. Le B. Tomlin 

 in this matter. He kindly replied (5/3/14) that B. elongatum is 

 certainly a Mediterranean species, and that it is a shell common 

 at Malta. In collections, it is generally known as Bittium 

 arenariitm Monterosato, a name which, if published, is doubtless 

 subsequent to B. elongatum. 



So Cerithiimi elongatum Sowerby, can now be eliminated from 

 the list of Australian shells.
