Japan. 



At first sight this shell might appear to be related to V. 

 rupestris^ from the same locality, but it differs in several 

 respects, and particularl}- in the character of the plicae. 



Sect. 11. Ausoba, H. iiml A. Adaii s. 



Spire short and obtuse, terminated by a papilliform summit ; 

 last whorl coronated. 



Y. CYMBiOLA (Chemn.), Sowb. PI. 29, figs. 118, 119. 



Pale yellowish gray clouded with a darker tint, and punctate 

 with chestnut ; aperture light chocolate. Length, 3 inches. 



Moluccas. 



The name was changed by Kiener to V. coi'onata because 

 cymbiola had already been used by Lamarck for another species 

 — an error, as Lamarck had not used the name at all. V. corona, 

 Chemn. (fig. 119), is only known hy the figure of a juvenile shell 

 in that author, copied by Sowerby in his Thesaurus. Mr. Crosse 

 believes it to be distinct, but I cannot agree to this, as it appears 

 to me to be a faded young cymbiola. The nucleus is supposed 

 to be proportionall}' much larger, but it is really not larger 

 than in Kiener's figure of V. coi'onata. Sowerbj^ says that corona 

 having, besides the four principal plica^, several smaller ones 

 above them, is a character not shared by cymbiola^ yet a charac- 

 teristic specimen of the latter, before me, has two very distinct 

 smaller plaits above the four principal ones. 



Y. KiRKi, Hutton.

 small number of blunt tubercles ; columella with four very

Said to be a Cymbiola ; not figured. Possibly a young shell.
