88 THE NAUTILUS. 



wliich in assamense is much nearer the aperture. The operculum of 

 nagaense does not appear to have so many whorls as our species, a 

 large part of the central portion being quite flat and smooth. These 

 characters appear to be constant in the numerous specimens I have 

 examined of both forms. 



DESCRIPTIONS OF NEW JAPANESE LAND SNAILS. 



BY HENRY A. PILSBRY AND ADDISON GULICK. 



Diplommatina uzenensls Pilsbry, n. sp. 



Shell dextral, cylindric-oblong, pale brown or nearly white, finely, 

 delicately and evenly costulate. Whorls 6, very convex, the upper 

 3 forming a short, cone, the last whorl contracted, a little distorted, 

 ascending in front. Aperture subcircular, nearly vertical, the peri- 

 stome continuous, flatly reflexed, duplicate, having a thin lamina or 

 second peristome close behind the lip in quite mature specimens. 

 Columella concave, ending in a tooth, as usual. Palatal fold less 

 deeply immersed than usual, lying to the left of rather than above 

 the aperture. 



Alt. 2.6, diam. 1.4, alt. and diam. of aperture 1 mm. 



Nishigo, Uzen (Mr. Y. Ilirase). Types no. coll. A. N. S., 

 from no. 510 of Mr. Hirase's collection. 



This species is the most northern yet known, I believe. It is de- 

 cidedly larger than D. pusilla Martens, somewhat smaller than D. 

 nipponensis Molldff., which is its nearest ally. The sculpture is about 

 the same as in nipponensis, but the cone of the spire is not nearly so 

 long, the later three whorls being large, while in nipponensis the last 

 two are wide, the four or five earlier strongly tapering. The palatal 

 fold is further to the left in D. uzenensis than in D. nipponensis, and 

 the aperture is comparatively larger. 

 Eulota callizona v;u\ maritima Gulick and Pilsbry, n. var. 



This name is proposed for the race inhabiting Awaji Island and 

 other districts mentioned below, specimens from Fukura, Awaji, being 

 the types. These differ from E. peliomphala and its varieties brandtii, 

 herhlotsi and nimbosa in the more conoidal form of the spire; from E. 

 callizona and its varieties chiefly in pattern of coloration. These are 

 as follows : 



(a) Purple-brown, with light buff streaks.
