perforation. Aperture lunate, the lip simple and thin, columellar 

 margin hardly thickened, dilated above, a triangular reflection 

 partially covering the perforation. 



Alt. 7, diam. 10 mm. 



Kunchan, Okinawa (Mr. Y. Hirase, No. 635). 



This species has about the size, form and appearance of the 

 American Gastrodonta ligera (Say), though the whorls are more 

 convex and less striate above, and there is, of course, no callus 

 lining the basal part of the interior. The generic position assigned 

 is somewhat doubtful. 



It is named in honor of my friend G. K. Gude, who has pro- 

 duced several meritorious papers upon Japanese land snails. 



Kaliella borealis n. sp. 



Shell minutely perforate, pyramidal with slightly convex lateral 

 outlines and flattened base, thin, corneous-brown. Surface some- 

 what shining, sculptured above with regularly spaced, very delicate 

 whitish hair-like striae, the base showing fine spiral strise, and ex- 

 cept near the periphery, minutely but rather roughly pitted. 

 Whorls 7, nearly flat, the suture but slightly impressed, narrowly 

 margined; the last whorl acutely carinate. Aperture rhombic, the 

 peristome thin and fragile, columellar margin abruptly dilated and 

 reflexed partly over the perforation. 



Alt. 3f, diam. 3J mm. 



Kayabe, Ojima, Hokkaido Island (Mr. Y. Hirase, No. 641). 



A rather straightly pyramidal species, distinct from any of the 

 numerous species known to me from Hondo. 



Eulota (Euhadra) oshimae n. sp. 



Shell globose-subdepressed, umbilicate, rather thin but solid, of 

 a rich reddish chestnut color, darker within the umbilicus and on 

 the back of the lip, and with a very dark chestnut, almost black 

 band just above the periphery, bordered above and below with 

 greenish-yellow bands ; the convexity of the base sometimes fading 

 to the same pale tint. Surface rather glossy, but in part dull, 

 sculptured with slight growth-striae only ; several inner whorls, 

 after the apical one, minutely wrinkled and marked with points in 

 oblique lines. Spire conic, more or less elevated. Whorls varying 

 from 6f in large to 5f in small specimens, quite convex, slowly 

 widening, the last rounded at the periphery, very slightly and
