ILLUSTRATIONS OF NEW SPECIES OF SHELLS. 



Note. — In the December, January and February numbers, plate II is referred 

 to erroneously as pi. I. All the figures of this plate are slightly magnified, being 

 one and one-third times natural size. 



Nanina (Ariophanta) Doliertyi Aldrich. PI. II, figs. 1, 2. 



This species was described in the December no., p. 90. 

 Bathybembyx Cmmpii Pilsbry. PI. II, fig. 3. 



This species Avas described in the January no., p. 105, as 

 Calliostnma Crumpii In the last number of the "Journal de Con- 

 chyliologie" (Paris), Mr, Crosse proposes the name Bathybembyx to 

 replace Watson's genus Bembyx (preoccupied). In it he places B. 

 OBo^a Watson, B. ar^enfeoni^esLischke,and also, with doubt, B. alwincB 

 Lischke. The last species should, I believe, be left in Calliostoma. 

 The others form a natural group of very beautiful shells, characterr 

 istic of the Japanese fauna. These shells are closely allied to 

 Solariella, but larger and imperforate. They seem very nearly 

 related to Ball's subgenus Turcicida, differing only in the very thin 

 (or lacking) epidermis. The species here figured is perhaps the most 

 beautiful of the three now referred to Bathybembyx. 

 Cypraea cruenta var. Greegori Ford. PI. II, figs. 4, 5. 



Described on p. 112, February, 1893.
