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, iigs. 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 G, 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 ; peri^tome 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.
