CHE NAUTILUS. 10* 



species in the Jour, of Conch., ix, pp. 244-246, Oct., 1899, was re- 

 viewed in the Nautilus, xiv, p. 34. Dr. Dall states that this part 

 carries the text so far that it seems certain that another part will 

 conclude the work. 



NOTICES OF SOME NEW JAPANESE LAND SNAILS. 



BY II. A. 1'ILSBRY, 



A recent sending from Mr. Y. Hirase, of Kyoto, Japan, contained 

 a n urn her of novelties, some of which are briefly diagnosed below. 

 Illustrations will follow later. 



Eulota (Aegista) mimula n. sp. Shell thin, openly umbilicate, de- 

 pressed, with low-conic spire ; brown, lustreless, rather weakly 

 striate, and bearing sparse cuticular processes, like short, prostrate 

 and adnate hairs. Whorls 5^, convex, the last a trifle angulated in 

 front, slightly descending to the aperture, rounded beneath. Aper- 

 ture oblique, subcircular, the peristome whitish, narrowly expanded. 

 subreflexed below, scarcely thickened, the margins approaching. 

 Alt. .1.5, diam. 9 mm. Kyoto. 



Much like a miniature E. aperta, but the spire, is somewhat 

 higher, the umbilicus rather less open, the striation less strong, and 

 the peristome not thickened within. 



Trishoplita cretacea var. bipartita n. v. Somewhat smaller than 

 T. cretacea, with conic spire, whitish above, brown or copiously 

 streaked with brown below, a brown line ascending the spire border- 

 ing the suture above ; surface striate and rather indistinctly granu- 

 late by the decussation of fine spirals. Aperture very oblique, 

 rounded oval. Alt. 9, diam. 14."» mm.; alt. 9.5 diam. 12.5 mm. 

 Toyonishikami, Nagato. 



In T. cretacea the minute granules are irregularly scattered, not 

 produced by decussation as in this variety. In specimens from 

 Ushirogawa, Tosa, Shikoku Island, which I refer to T- cretacea as a 

 variety, the sculpture is also decussate, though very indistinctly so. 

 T. cretacea v. bipartita reminds one somewhat of Helicella pyramid 'ata, 

 from the form of the spire. 



Eulota (PI ctotropis) elegantissima var. cara n. v. Larger than 

 E. elegantissima, more depressed, with wider umbilicus and more 

 rapidly widening last whorl. Alt. 10, diam. 29 ; alt. 7, diam. 

 20i mm. Loochoo Is.
