carinate throughout. It differs from K. ceratodes in the sculpture of 

 the early whorls as well as by the less developed peripheral keel. 



K. liocouus goniozona n. subsp. 



This form of the species is smaller, alt. 3.6, diam. 4.1 mm., a trifle 

 higher in proportion, with 6 whorls. 



Amagisan, Izu. Types No. 90,227, A. N. S. Phila., from No. 1,314 

 of Mr. Hirase's collection. 



About a dozen specimens were taken. 



Kaliella affinis n. sp. 



Shell minutely perforate, low-trochiform, thin, yellowish-corneous, 

 subtranslucent. Surface glossy, the base smooth, upper surface faintly 

 striolate vertically, especially the earlier whorls. Spire conic, the apex 

 obtuse, lateral outlines a trifle convex, nearly straight. Whorls 5^, 

 very convex, the last with a narrow, acute peripheral keel. Aperture 

 truncate-lunate, the columellar margin dilated above, slightly thick- 

 ened within. 



Alt. 2, diam. 2.6 mm. 



Harutori and Akkeshi, Kushiro. Cotypes No. 90,228 and 90,229, 

 A. N. S. Phila., from No. 1,145 and 1,145a of Mr. Hirase's collection. 



This specimen is more depressed than K. harimensis , and more cari- 

 nate. K. hachijoensis has not the faint vertical striation of affinis. 

 In shape it is much like the larger K. humiliconus. Microcystina 

 higashiyamana differs by its glossy upper surface, without vertical 

 striation. 



Kaliella crenulata basistriata n. subsp. 



Shell similar to K. crenulata but larger, with the base radially thread- 

 striate like the upper surface. 



Alt. 4.2, diam. 4 mm., whorls 7. 



Alt. 3.7, diam. 3.3 mm., whorls 6^. 



Yakushima, Osumi. Types No. 87,934, A. N. S. Phila., from No. 

 1,283 of Mr. Hirase's collection. 



In K. crenulata the base is smooth, and that species has not been 

 found in Kyushu or southward up to this time. 



ENDODONTID^. 

 Punctum boreale n. sp. 



Shell depressed, umbilicate, dark brown, thin, dull; whorls 3^, the 

 first li smooth, the rest with oblique, coarse, widely, irregularly spaced 

 wrinkle-like ribs, the intervals and ribs finely striate spirally. Whorls 

 convex, the last rounded peripherally and below. Umbilicus some-
