etc., also. Tlie spaced costulation of the initial whorl is a character- 

 istic though not invariable feature of Kaliella. 



It is named in honor of Lieut. -Col. H. H. Godwin-Austen, whose 

 work on the Indian Zonitldse is destined to become a malacological 

 classic. 



KalieHa yaeyamensis n. sp. 



Sliell narrowly perforate, rather low conic, thin, reddish brown. 

 Surface slightly shining above, glossy beneath, sculptured with rib- 

 striae comparatively coarse for a Kaliella (but still very tine), contin- 

 uing on the first whorl, obsolete on the base, and excessively minute 

 spiral striae. Whorls 4|, moderately convex, the last angular (but 

 not acutely so) at the periphery, not very convex beneath. Aper- 

 ture oblique, broadly crescentic, the lip thin and simple, dilated at 

 the columellar insertion. Alt. 2, diarn. 3 mm. 



Yaeyama Island (Mr. Y. Hirase, no. 625). 



With K. nn/iaensfs Gude, this makes three species of KalieHa now' 

 known from the Loo Clioo Islands. K. nahaensis has fine, almost 

 subobsolete sfrire, and a peripheral keel, thus differing decidedly from 

 the two species described above. 



Kaliella ruida n. sp. 



Shell perforate, in shape resembling Microcystina ceratodes (Gude). 

 Acutely keeled, thin, brown, somewhat translucent, sculptured above 

 and in a hand around the base, below the periphery, with sharp, 

 close and regular rib-stria? ; the rest of the base ^lossv, with very

minute spirals only. Whorls 3^, moderately convex above, the last 

 quite convex beneath. Aperture wide-crescentic, peristome thin, 

 fragile. Alt. 2, diam. 3.5 mm. 



Gojo, Prov. Yamato, Japan (Mr. Y. Hirase, no. GOT). 



I am disposed to believe this shell, of which but two specimens 

 were sent, is not full grown, and will be found to attain a larger size; 

 but the sculpture is so conspicuous and so unlike anv known species 

 of similar shape, that its recognition will be easy. 



Georissa luchuana n. sp. 



Shell small, globose-turbinate, dull red, composed of nearly 3^- 

 very convex whorls, the first glossy and smooth, with rather large 

 apex, the rest rapidly increasing, closely and regularly striated or 

 lirulate spirally. Last whorl large and obese. Aperture oblique,
