THE NAUTILUS. 81 



This species somewhat resembles Hyalina pustulina Reinhardt, but 

 it is proportionately higher, smaller, the last whorl less enlarged, the 

 spire being more prominent ; consequently the aperture is smaller. I 

 would consider this shell an Euconulus were it not so closely allied 

 to the following species, which I do not doubt is a Kaliella. Half- 

 grown specimens are still only obtusely angular at the periphery. 



Kaliella fraterna n. sp. 



Shell similar to K. symmetrica, except that it has an acute, pro- 

 jecting, thread-like peripheral keel, like that of K. labilis (Gld.), ex- 

 tending undiminished to the aperture. 



Kashima, Harima, with K. symmetrica (Mr. Y. Hirase). 



Euconulus Reinhardti n. sp. 



Shell globose-conic, perforate, fragile, pale corneous yellow ; 

 glossy, with sparse rather conspicuous oblique growth-wrinkles and 

 extremely fine subobsolete, crowded spiral stria 3 . Spire elevated, 

 the apex rather acute. Whorls .H, quite convex, separated by 

 deeply impressed sutures, the last whorl large, subglolose, rounded 

 at the periphery, but showing the almost obsolete trace of a peri- 

 pheral angle ; base strongly convex, slightly impressed around the 

 narrowly perforate axis. Aperture somewhat oblique, roundly 

 lunate the peristome thin, very fragile, simple, the columellar margin 

 rather broadly dilated above. Alt. 3.9, diam. 3.7 mm. 



Kashima, Harima (Mr. Y. Hirase). 



A jrlobose-conic species which I first thought to identify with H. 

 pupula Gould ; but it differs from that insufficiently defined species 

 in t lie rounded last whorl and various other characters. 



It has been shown that the name Conulus is preoccupied in Mol- 

 lusca by Rafinesqne, Avho proposed that name for the genus Conus. 

 This will prevent its use for the common Helix fulva of Muller, and 

 various European authors have now abandoned Conulus in favor of 

 Arnouldia of Bourguignat. It has apparently escaped the notice of 

 these gentlemen that Euconulus of Reinhardt was proposed for the 

 fulvus group some seven years before Bourguignat's publication. 

 The genus will therefore stand thus : 



Euconulus Reinh. 

 Comdus Fitz., 1833, not of Rafinesque, 1814.
