In the British Museum, I compared one shell marked as the type 

 of L. acutissima Sowerby, with an example of L. lesbia, presented 

 by Angas, and, therefore, probably type, but not so marked. These 

 two have already been united by Tryon. To me, L. lesbia seemed 

 the adult form of L. acutissima. 



Eulima proxima Sowerby.

The late Prof. R. Tate concluded,* from a study of the British 

 Museum series, that Eulima proxima of Sowerby was the same as 

 E. augur Angas. I found, in the South Kensington collection, one 

 specimen marked type, of E. proxima Sowerby, from Port Jack- 

 son, presented by G. F. Angas. Again, there are two specimens 

 marked types, E. augur Angas, from St. Vincent's Gulf, also pre- 

 sented by G. F. Angas. These seems to me to be different species. 

 E. proxima is shorter and broader, with flatter sides, and more 

 sharply angled periphery than E. augur. E. proxima has the aper- 

 ture angled in front, where in E. augur it is rounded. All three 

 types have imperfect tips. That of E. proxima has eleven whorls 

 remaining; there are very faint lateral varices. There are, in the 

 same collection, three specimens of E. subangulata Sowerby, f 

 marked "Indian Seas, from the Old Humphries Collection, M.C." 

 These may possibly be the adult form of E. proxima.
