reflexed peristome; the right and left margins scarcely converging 

 above, xvidehj separated, connected by a thin, adnate jmrietal 

 callus. The superior lamella is minute, short and removed from 

 the edge of the parietal callus. It is widely separated from the 

 rather short, spiral lamella. Inferior lamella receding, small, 

 becoming higher inside, extending to a dorsal position. Sub- 

 columellar lamella very deeply immersed, a long pit between it 

 and the inferior lamella. There are no plicse. Clausilium want- 

 ing. Length 8.3, diam. above aperture 2.6, length of aperture 

 2.8 mm. 



Tago (A. Adams) (Tako, in western Shikoku, province of 

 lyo) ; Uweno, near Tokyo, and Ujeno (Hilgendorfj ; Tokyo 

 (Donitz); Takasaki, prov. Kozuke (Y. Hirase, jSTo. 525). 



This species was found by Hilgendorf under the bark of trees, 

 by Donitz in hollow trees. It is viviparous, one specimen I 

 opened containing a young shell. 



Clausilia Eastlakeana Mlldff., of which I have specimens, from 

 the original locality, is undoubtedly nearer variegata than any 

 Japanese species, having the same discontinuous peristome; but it 

 has longer, stronger lamellae, palatal phcse and an Euphredusoid 

 clausilium. 

 Clausilia (Reinia) variegata var. nesiotica nov. PI. XXV, flgs. 9, 10. 



Whorls &h; striatiou stronger than in variegata, the last whorl 

 with fine incised spiral strife. Inferior and spiral lamella de- 

 cidedly more strongly developed. 



Length 8.3-9.5, diam. 2.7 mm. 



Hachijo Island, off Izu (Mr. Y. Hirase, No. 5256). 



This insular race has slightly less degenerate lamella; than the 

 typical form from Hondo. Some specimens from the outlying 

 Ogasawara (Bouin) Islands, Mr. Hirase's No. 469, apparently 

 belong here, though as only young ones have been received, I am 

 not certain of them. 



Section TYRANNOPH.EDUSA Pilsbry. 



This section is not allied to Eaphcedusa, as I formerly supposed, 

 but to Heviiphitdnsa, with which it agrees in the receding inferior 

 lamella, straightly ascending within, and remote from the superior 

 lamella. Whether it will stand as a separate section, or become a 

 subordinate group of Hemiphcednsa, depends upon the emphasis
