GUDE : HELICOLD LAND SHELLS FROM JAPAN, ETC. 1 I 



15. Eulota (j-Egista) Friedeliana, Mts. Hirado, Hirado Island. 

 Forty specimens. Hitherto only recorded from Nagasaki. 



16. Eulota (JEglsta) Awajiensis, n.sp. PI. II, Figs. 8-10. 



Shell widely and deeply umbilicated, conoid, depressed, finely 

 striated, dark horn - coloured ; spire conical, apex prominent, suture 

 impressed. Whorls 6, slowly increasing, a little convex ; the body- 

 whorl rather flattened above, rounded below, bluntly keeled, very 

 shortly deflected in front. Aperture oblique, ovate ; peristome 

 strongly thickened, shortly reflected, shining, white, the margins 

 approaching and united by a thin callus ; columellar margin sub- 

 vertical. Umbilicus wide, perspective. Diaru. maj. 13 - 5, min. 12 mm. ; 

 alt. 8 mm. 



Hob. — Fukura, Awaji Island. 



This new species I took at first to be a variety of the preceding ; 

 but it presents specific differences, and it will be noted that the 

 habitats of the two forms are widely apart. E. Awajiensis may 

 be distinguished from its ally by its darker colour, more elevated 

 spire, and narrower umbilicus ; and, although a smaller shell, it 

 possesses half a whorl more ; the whorls widen more slowly, the last 

 being but little wider than the penultimate, whereas in E. Friedeliana 

 it is nearly twice as wide. The body- whorl in E. Awajiensis is more 

 compressed and distinctly keeled ; and while E. Friedeliana is spirally 

 wrinkled, the new species is without sculpture and devoid of the 

 short bristles which characterize the former. The peristome is more 

 thickened in the latter, which resembles in this respect E. Eobensis ; 

 it is, in fact, intermediate between that species and E. Friedeliana ; 

 but the umbilicus of E. Eobensis is wider than that of the other two. 

 Five specimens were received. 



17. Eulota (Euhadra) Senckenbergiana, Kob., var. (Kobelt : 

 Fauna Japon., pi. iii, figs. 8, 9.) Takeya, province Idzumo. Twenty- 

 six specimens. Hagi, province Nagato. One specimen. The typical 

 form of this fine species appears to be rare, the only specimens I have 

 seen being the types in the Senckenberg Museum, Frankfort. Although 

 E. Senckenbergiana is, perhaps, only one of the numerous manifestations 

 of that protean assemblage of forms usually classed together under 

 the designation of E. Luhuana, for convenience it may be retained 

 as a distinct group. The variety now under consideration may be 

 distinguished from the other members of the E. Luhuana group by 

 the deeper umbilicus, which is less excentric, and shows the earlier 

 whorls more distinctly. The whorls are more inflated, the shell is 

 more conical and much coarser in texture, resembling in appearance 

 the Calif ornian species of Epiphragmophora to a remarkable degree. 

 Several specimens show distinct traces of the two wide, diffused bands 

 near the mouth, one above and one below the peripheral band. The 

 inside of the umbilicus is dark in all my Takeya specimens. 

 Diam. maj. 36, min. 31 mm. ; alt. 25 mm.

 measures: diam. maj. 38, min. 33mm.; alt. 26mm.
