100 FULTON : NEW SPECIES OF LAND SHELLS. 



Coehlostyla delicata, n.sp. 

 PL ix, fig. 10. 



Shell pyramidally ovate, very slightly perforate, shining, first two and 

 last whorls pure opaque white, middle whorls yellowish with irregular 

 oblique whitish stripes, inconspicuously obliquely striated, and with 

 numerous impressed spiral lines ; whorls 6, moderately convex, regu- 

 larly increasing ; suture impressed ; aperture sub-ovate, interior white ; 

 peristome slightly thickened, behind the peristome is a dark brown band 

 about 2 millim. wide which shows through inside of aperture as a bluish 

 colour, and joins the brown margin of peristome, giving it the appear- 

 ance of being broadly expanded. 



Maj. diam. 19 ; alt. 40 millim.

 This distinct species (probably from New Ireland or New Britain) is 

 allied to C. hindei, Cox, and C. heimburgi, Brancsik. 



It bears a superficial resemblance to some varieties of C. calobapla, 

 Jonas. 



StFophocheilus (Borus) separabilis, n.sp. 

 PI. ix, fig. 12. 



Shell oblong-ovate, imperforate, yellowish-brown below, darker on 

 embryonic whorls which are margined above with golden-yellow ; whorls 

 5, rapidly increasing, embryonic portion consisting of 3^ whorls, clearly 

 marked ofi and obliquely striated except first whorl which is smooth, 

 the last 1| whorls strongly malleated ; aperture sub-ovate, brown within ; 

 peristome thickened and slightly exjmuded at basal and columellar 

 margins, pinkish fading to whitish at point of insertion, margins connected 

 by a very thin, well-defined, whitish callus. 



Maj. diam. 36 ; alt. 63 millim. 



Hob. — ? (probably Peru). 



Easily distinguished from other species known to me, by its strongly 

 malleated surface and thin substance. 



Odontostomus (Morieandia) toleratus, n.sp. 

 PI. ix, fig. 2. 



Shell narrowly but deeply rimate or umbiUcate, fusiform, rather thin, 

 slightly pofished, light yellowish brown with indentations darker, upper 

 part almost smooth, lower whorls distinctly malleated and crossed by 

 microscopic close-set impressed spiral fines only visible under the lens ; 

 suture of lower part sub-crenulate ; whorls 8|, sfightly convex, tapering 

 at the base, aperture narrowly oblong, interior with a blackish stripe 

 bordering the peristome, and continued at back of columellar fold, 

 white in the throat ; peristome slightly pressed outwards, white mar-
