elongate and a trifle less solid. This conclusion is arrived at 

 after a careful study of a good series of specimens, among 

 which the connecting links are found. Sowerby (Conch. Icon, 

 xvii. sp. 4) says, in reference to soltda, " it may possibly be a 

 dwarf variety " of cylindrica. 



Atys ovoidea^ Quoy & Gaimard,^(^e A. Ad. Thes. Conch, ii. 

 p. 585, pi. 124. %. Ill ; and Sowerby, Conch. Ic. pi. i. f. 3. 



The shell figured in the above works is not the Bulla ovoidea 

 of Quoy and Gaim. Voy. Astrol. pi. 26. f. 18, 19. 



These authors describe it as a fragile species, '' tr^s-ldg^re- 

 ment stride en long avec d'autres stries trans verses et peu 

 nombreuses ew avant seulement.^^ These characters, together 

 with the figures, at once separate it from the species referred 

 to it by Adams, which is the Atys obovata, Menke, Malak. 

 Blatter, 1854, p. 46. Sowerby, in the remark on this shell 

 (sp. 3), says it " may only be a dwarf variety oiAtys naucum^^'' 

 in which opinion I concur.

The specimen from which Mr. Sowerby figured this species 

 is fixed to a tablet, on which the name and locality are written 

 thus : — " Atys por-ceUana, Gld. Kagosima, W.S.," Gld. being 

 the contraction of Gould ^ and W. S. the initials of William 

 Stimpson, who collected the shells, and not signifying Western 

 States. I give this explanation to show that the error doea 

 not exist in the Museum collection.
