PLACOSTYLUS, NEW CALEDONIA. 31 



supposed to be from Eddystone Island in the Solomon group ; but 

 subsequent researches locate the species in New Caledonia. To 

 obviate the error as to locality implied in Pfeiffer's specific name, 

 Crosse re-named the species B. hienguenensis ; and Frere Euthyrne, 

 thinking the New Caledonian shell different from the supposed Solo- 

 mon Island species, called it B. servaini. 

 P. BAVAYI (Crosse & Marie). PI. 7, figs. 13, 14. 



Shell nearly covered perforate, ovate-conic, somewhat inflated, 

 rather thick, solid, very delicately striated and closely rugate- 

 malleate. Dirty whitish rose under a chestnut epidermis, which is 

 largely deciduous in adults. Spire conic, the apex sub-acute, 

 suture somewhat crenulated. Whorls 6, convex, somewhat inflated, 

 the last not descending, longer than the spire, ventricose, receding 

 toward the right, obliquely rotund -at base. Columella subplicate, 

 receding. 



Aperture very oblique, broadly subangulate-oval, glossy and pale 

 orange-livid inside ; perutome simple, thickened, of a rather bright 

 orange color, the terminations joined by a thick and prominent 

 parietal callus which bears a strong, median, deeply placed tooth. 

 Columellar margin expanded, dilated, partly covering the perfora- 

 tion ; basal and outer margins somewhat thickened. Length 74, 

 diam. 43, length of aperture with peristome 41^ mill. (Crosse). 



Summit of Mt. Mou, New Caledonia (Marie).

" It is one of the thickest of the thin-lipped group of New Cale- 

 donian Placostylus. The last whorl has a tendency to be inclined to 

 the right ; the aperture is quite markedly oblique." It is a rare and 

 local species. 

 Var. dupuyi Kobelt. PI. 7, figs. 15, 16. 



Shell rimate-perforate, acutely ovate, comparatively thin but solid, 

 dark brown, the cuticle becoming yellowish-chestnut on the penult, 

 whorl, those earlier being nude and roseate. Surface with slight, 

 irregular growth-wrinkles, and conspicuously malleated throughout. 

 Spire small, conic, slightly attenuated above ; whorls 5-| or 6, the last 

 very large. Aperture somewhat oblique, ovate, bluish inside ; peri- 

 stome simple, but slightly thickened, pale orange ; columella concave, 

 dilated; parietal callus thin, whitish and toothless.
