umbilicus. The spiral sculpture is scarcely perceptible under 

 a strong lens. A specimen in the collection of Mr. S. J.

 little more shining and smaller than the type, measuring : —

Oanesella tosana, sp. n. 



Shell narrowly umbilicated, depressed- conoid, finely stri- 

 ated, decussated with fine spiral lines, thin, pellucid, a little 

 shining below, silky above, with a broad milky-white band 

 under the suture, the umbilical region more or less clouded 

 with milky white. Spire depressed, apex prominent, suture 

 impressed. Whorls 5^-6, rounded, increasing rather rapidly, 

 the last widened towards the mouth, descending shortly in 

 front, obsoletely angulated at the periphery ; aperture oblique, 

 ovate-rotundate ; peristome thin, acute, margins convergent, 

 the lower expanded, the columellar margin reflected over the 

 narrow deep umbilicus.

Hab. Ushirogawa, Tosa Island. Type in my collection. 



The present species is allied to G. Hilgendorji, Kob., but 

 it is thinner, more depressed, and with narrower umbilicus.

Shell sinistral, deeply umbilicated, conical ; embryonal 

 whorls smooth, the others finely regularly ribbed, the inter- 

 stices minutely spirally striated ; thin, glossy, subpellucid, 

 the earlier whorls pale corneous, the later ones straw-yellow. 

 Spire elevated, apex obtuse, suture margined. Whorls 6|, 

 rounded, increasing somewhat rapidly, the last shortly de- 

 flected in front, angulated at the periphery, becoming rounded 

 and widened at the mouth, a little flattened below. Aperture 

 oblique, broadly lunate; peristome rather thin, white; mar- 

 gins approaching, upper straight, acute, outer and lower
