ture wide, semicircular, banded within, somewhat oblique; peris- 

 tome thin, narrowly expanded throughout, white-edged, the 

 columellar margin dilated, purple-black, partially covering the 

 umbilicus. 



Alt. 26^, diam. 25 mm. 



Alt. 24, diam. 221-23^ mm. 



Oshima (Amani-Oshima), Mr. Y. Hirase, No. 352. 



This charming species is closely related to G. Largillierti of 

 Okinawa, and has also some superficial resemblance ^ to Eulota 

 •calUzona var. Dixoni. It differs from the former in the larger 

 umbilicus and the pyramidal rather than turbinate contour. 



A specimen I dissected has the exceedingly long' kidney and 

 characteristic genitalia of Ganesella. As its close relationship to 

 Largillierti is obvious, that species can no longer be placed in 

 Eulota, as some authors have done, 

 Trishoplita hilgendorfi var. tenuis nov. 



Closely resembling T. hilgendorfi (Kob. ), this'^form differs in 

 being thinner with perceptibly larger aperture, and the surface is 

 seen under a lens to be finely decussate, the fine growth-wrinkles 

 being cut into spiral series of long granules. Pale corneous- 

 brown, with inconspicuous darker streaks. 



Alt. 9|^, diam. 14-15 mm. 



Ibuki, Omi (xMr. Y. Hirase, No. 310c). 



Trishoplita coUinsoni var. okinoshimae nov. 



Similar to var. casta, but not papillose, distinctly decussate, 

 especially beneath, with a reddish-chestnut band at the slightly 

 angular periphery. Whorls 5| to 6. 



Alt. 10|, diam. 15 mm. 



Alt. 9, diam. 13 J mm. 



Okinoshima, Tosa. Type No. 81,884, Coll. A. N. S. P., from 

 No. 691 of Mr. Hirase' s collection. 

 Kaliella praealta n. sp. 



Shell perforate, pyramidal, pale brown, the surface glossy and 

 smooth. Spire very high, straightly conic, the apex obtuse, 

 whorls 9, convex, the last angular at the periphery, convex 

 beneath. Aperture semicircular, the lip thin as usual, columella 

 vertical, triangularly dilated above. 



Alt. 4, diam, 2|- mm.
