C. Var. Nipponensis. Kobelt. 



Kobe, province Setsu. Six specimens. 



Transversely streaked alternately with brown, pale corneous, 



and straw yellow. Differs from typical Nipponensn in having 



a dark umbilical patch and a dark-brown, narrow or broad, 



second band, which in one specimen, however, is almost 



obliterated. 



Diam. maj. 34, min. 28 , 5rnm.; alt. 22 mm.

16. Eulota (Euiiadra) Blakei, Kob. = E. Blakeana, Gude, non 



Newc, ante, p. 16, pi. ii, figs. 18-20. Yadonobe, province Oshima, 



Island Yezo. Thirty specimens. The banded and bandless forms 



are in about equal proportions ; one specimen has only a single 



supra-peripheral band. This form was erroneously referred by me to 



E. Blakeana. Mr. Pilsbry informs me that Newcomb's species, the 



type of which has been examined by him, is quite distinct. He 



thinks Kobelt's name for the present species should stand, since the 



variation in spelling is sufficiently different and involves a different 



meaning. 



17. Eulota (Euhadra) sericea, n.sp. PI. VIII, Figs. 12-14. 



Shell umbilicated, depressed, discoid ; finely ribbed anil decussated 

 with incised spiral lines ; unicolorous grey corneous, thin, pellucid, 

 with a silky gloss ; spire low conoid, apex obtuse, suture impressed. 

 "Whorls 6, increasing regularly, a little convex above, inflated below ; 

 the last bluntly angulated above the periphery, suddenly widened at 

 the mouth, not descending in front. Aperture oblique, roundly 

 lunate ; peristome scarcely thickened, acute, expanded ; margins 

 converging, united by a thin callus on the parietal wall ; columellar 

 margin slightly reflected over the moderately wide, deep, perspective 

 umbilicus, which allows all the whorls to be seen distinctly. 

 Diam. maj. 30-29, min. 25-24"5mm.; alt. 16-15-5 mm. 



Uab. — Teshio. 



Type in my collection. Two specimens. 



The nearest ally is E. Blakei. The Lewis Collection of the British 

 Museum contains two unnamed shells, which I refer to this species. 

 The width of the umbilicus appears to be somewhat variable.
