THE NAUTILUS. 117 



7jj, slightly convex, the last slightly angular at the periphery in 

 front, a little descending to the aperture, convex beneath, Aperture 

 oblique, the peristome thin, everywhere arcuate, narrowly expanded 

 and reflexed, triangularly dilated at the columellar insertion. Alt. 

 14^ to l.H, diain. 1<H mm. 



Suimura, Prov. Awa. Shikoku Island (Mr. Y. Hirase, no. 824.) 



A charming species, unlike any other Japanese Ganesella in its 

 elevated shape. 



Macrochlamys cerasina n. sp. Shell perforate, depressed, with 

 low-conic spire, dark-reddish amber colored, brilliantly glossy, with 

 faint growth-lines, no spiral stria?. Whorls 5^, convex, slowly in- 

 creasing, separated by impressed sutures, the last whorl perceptibly 

 angular at the periphery in front, convex beneath. Aperture slightly 

 oblique, lunate, the lip simple and thin, abruptly dilated and reflexed 

 in a minute triangle at the columellar insertion. Alt. a. 7, diam. 

 8.6 mm. 



Tobishima, Prov. Ugo (Mr. Y. Hirase, no. 838). 



M. cerasina var. awaensis n. v. Shell paler, with lower spire and 

 (5 more closely coiled whorls. Alt. 4.2, diam. 7.8 mm. 



Tairiuji, Awa, Shikoku Island. Although remote from the pre- 

 ceding geographically, this form seems to me to be too similar for 

 specific separation. 



Eulota (Ocelot-its) caviconus n. sp. Shell small, thin, with a large, 

 deep umbilicus, conic above, flattened beneath, reddish-brown, lustre- 

 less, the surface roughened by short cuticular processes like adnate 

 hairs, usually in part worn off. Outlines of spire a little convex, 

 the apex obtuse. Whorls about 7^, the earlier a little convex, the 

 later ones flattened ; the last whorl acutely carinate at the periphery, 

 abruptly and deeply descending in front, contracted behind the lip. 

 Aperture small, subhorizontal, oblong, the peristome expanded above, 

 reflexed below, the ends approaching. Alt. 4, diam. 6^ mm. 



Goto, Uzen (Mr. Y. Hirase, no. 815). 



This peculiar species is related to E. cavicollis Pils , differing in 

 the flattened whorls and carinnte periphery. 



Mandarina exoptata n. sp. Shell narrowly umbilicate, depressed, 

 biconvex, solid, light brown, the early whorls darker. Surface 

 beautifully sculptured with crowded, spirally engraved, crimped lines, 

 cutting irregular growth-wrinkles, the spirals obsolete immediately 

 around the umbilicus. Spire low conic. Whorls 4^, the first 1| or
