14 NOTE ON THE SUBGENUS SALINATOR OF HEDLEY. By Edgar A. Smith, F.Z.S., Cokr. Mem. Ill the last Part of the Proceedings of this Society (Vol. xxv., p. 511) Mr. Hedley has suggested a new subgeneric name (Salinator) for the Australian shell commonly known as Amphi-hola fragilis, to take the place of Ainpullarina of authors which he shovvs to have a different signification from the Amqnillarina of Sowerby. In his remarks he merely casually refers to the genus Ampul-lacera of Quoy and Gaimard, described in 1832*, which included both the genus Amphibola as restricted by Mr. Hedley, and the subgenus Ampullarina, auct. ( = Salinator). The question first of all arises whether there are sufficient grounds for subgeneric separation, and secondly, if this be granted, whether the name Ampullacera should not have been used. It is a recognised custom, where an author has included various forms under one generic title, for his successors to limit the genus, retaining the original name, and to apply fresh terms to the forms considered distinct. As Messrs. Quoy and Gaimard did not indicate either species in particular as the tj'^pe of their genus, it is open to any succeed-ing writer to apply the name Amindlacera either to A. aveUana or to A. fragilis, supposing he considers them generically or subgenerically different. Now, as the species avellana was previously, in 1817, appro-priated by Schumacher as the type of his Amj^hihola, it could not be retained for Ampullacera, and, therefore, it seems to me that Mr. Hedley would have acted more wisely if he had used * V'oy.
