20 THE NAUTILUS. 



ern end of Shikoku Island. It has not been figured, but is said to 

 be " globoso-conica," ll late perforata," with a \vi<le peripheral band 

 and lunate aperture. None of these terms would I apply to the 

 shells before me, though it is by no means impossible that my species 

 is a variety of that of Adams. T. lischkeana is from Hagi, on the 

 north coast of western Hondo. It is a smaller shell than T. casta, 

 with narrower umbilicus. When these forms of Tfishoplita are bet- 

 ter known, I believe they will be seen 'to fall under a few specific 

 heads, like the peliotaphala group of Euhadra.' It is likely that col- 

 linsoni, casta, lischkeana^ bipartita and cretacea are varying races of 

 one species, and will be found to intergrade on the confines of their 

 several areas. T. collinsoni is the senior name for the group, which 

 has about tlie distribution of Eulota callizona var. maritima G. & P. 

 Shikoku, eastern Kiushiu and western Hondo. 



Trishoplita hiugensis n. sp. Shell depressed, rather narrowly 

 umbilicate, brownish yellow, the suture bordered below with a nar- 

 row white band ; very glossy, finely striatulate. Spire low-conic, 

 the apex obtuse. Whorls 4|, convex, the last slightly derlexed in 

 front, indistinctly angular al the periphery in front, becoming 

 rounded on the latter portion. Convex beneath. Aperture shaped 

 like that of T. tosana, the lip expanded, refiexed below. Alt. 6.4, 

 diam. 9.4-9.8 mm. 



Obi, Prov. Hyuga, Kiushiu (Mr. Y. Hirase). 



A smaller, less conoidal form than T. fosona or T. rfacost(E, with 

 fewer whorls. It is No. 601 of Mr. Hirase's collection. 



Kaliella Austeniana n. sp. 



Shell distinctly perforate, turbinate-conic, thin, light reddish 

 brown. Surface very minutely sculptured with densely crowded 

 rib-striae, which give it a silken luster, and give place on the more 

 glossy base to slight growth-wrinkles and fine spiral stria 3 . Whorls 

 nearly 6, very convex, the first one sculptured with much more 

 spaced rib-stria:- ; last whorl obtusely subangular at the periphery, 

 quite convex beneath. Aperture oblique, rather broadly crescent 

 shaped ; peristome simple and thin, the columellar margin dilated 

 above. Alt. 2.7, diam. 6.2 mm. 



Yaeyama Island (Mr. Y. Hirase, no. 627). 



In this species the minute stria- continue below the periphery, and 

 form a silken band around the base, the central two-thirds of which 

 is more glabrous. This has been noticed in J'ucomdus, Guppya,
