PARTULA, NEW HEBRIDES. 279 



A slender shell resembling P. turneri in coloration. The 

 spiral lines are distinct and rather widely spaced on the 

 penultimate whorl and obsolete on the last whorl except in 

 the base. There is a faint band below the periphery, as in 

 the allied species. The apical whorls are shaped like those 

 of P. Irazieri, figured on plate 33, fig. 2. Specimens 

 measure : 



Length 21.8, diam. 12, aperture 11 mm. ; whorls 5%. 



Length 20, diam. 10.5, aperture 10.9 mm. 



67. P. NEMATORAPHE Pilsbry, n. sp. PI. 35, figs. 1, 2, 3. 



The shell is ovate-conic, rather thin, white under a thin, 

 pale, yellowish green cuticle, which is darkest at the base, fad- 

 ing upward to corneous- whitish on the upper whorls, the last 

 whorl having narrow streaks of a darker shade at irregular 

 intervals. Surface glossy. Embryonic shell -of fully 2y 2 

 whorls is very minutely punctate-striate spirally; following 

 whorls are more convex, with rather distinct oblique growth- 

 strise but only very faint and fine traces of spiral lines, ex- 

 cept on the last whorl, which is distinctly striate spirally on 

 the base and somewhat malleate behind the outer lip. The 

 last whorl is full, rather swollen above the periphery, then 

 tapers to the narrow, very convex 'base. The umbilical chink 

 is deep and ample. Whorls nearly 5%> separated by a well- 

 impressed suture, which in the last two whorls is bordered 

 above by a low cord defined by a groove. This margin is cov- 

 ered by the ascent of the last whorl near the aperture, but 

 may be traced faintly on the last whorl, though it is there 

 very indistinct. The aperture is vertical, white within. 

 Outer lip narrowly reflexed, white, thickened within. Colu- 

 mellar margin broadly dilated above. The lip-callus extends 

 somewhat more than half way up to the insertion, where it 

 terminates in a small but distinct nodule. Parietal callus 

 thin, transparent. 



Length 21.7, diam. 12.5, aperture 12 x 9 mm. 



Length 21, diam. 12, aperture 11 x 8.3 mm.
