etc., also. The spared costulation of t he 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 Zonitidse is destined to become a malacological 

 classic. 



Kaliella yaeyamensis n. sp. 



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

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

 stria; comparatively coarse for a Kaliella (but still very fine), contin- 

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

 spiral stria;. Whorls 4j, 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, diam. 3 mm. 



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



With K. nahaensis Gude, this makes three species of Kaliella now 

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

 subobsolete stria;, and a peripheral keel, thus differing decidedly from 

 the two species described above. 



Kaliella ruida n. sp. 



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

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

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

 close and regular rib-stria' ; tin- rest of the base glossy, 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. Yainato, Japan (Mr. Y. Hirase, no. 007). 



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 any 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,
