STUDIES ON AUSTRALIAN MOLLUSCA, X., 



here mentioned that a cotype of Liotia Walkeri* Sowerby, proves 

 identical with Z. devexa described in the fourth Part of these 

 Studies.

This name was given to a shell gathered by Jukes at Cape 

 Upstart, Queensland. The cotype lent me is obviously D. delphi- 

 nus Linne var. melanacantha Reeve, f of which it may sink as a 

 synonym. No subsequent writer appears to have noticed this 

 species.

 Ann. Mag. Nat. Hist. (2) xiii., Feb. 1854, p.156. 



This hitherto unfigured and unrecognised species was, in the 

 above description, reported from " Australia." The cotype 

 figured is 24 mm. in length. It appears to agree with fig. 51 of 

 Nassa, Conch. Icon. viii. This illustration is quoted by von 

 Martensj: for JVassa marginulata Lam., var. hepatica Pulteney.

The cotype lent me by the British Museum is figured and 

 described as follows: — Shell slender fusiform, contracted at the 

 base, spire acuminate slightly turreted. Remaining whorls 10. 

 Colour milk-white with two narrow orange bands each covering 

 about three spirals, one below the suture, the other on the peri-
