MARINE SHELLS OF THE CHE VERT EXPEDITION — HEDLEY. 127 



the unrecognised C. tubidus, Dunker,^" from Bass Straits belongs 

 to this genus, and, further, that it is probably synonymous with A. 

 serotinu'tn = A. rhodostoma. So arranged the genus would contain 

 two recent and one fossil species.
