 SIES, Faune Conch. N.-Caled. ii, p. 92, 188 Pseud op artula sinis-

 C., 1894, p. 246, 247. 



Deshayes' single specimen had lost the early whorls, and in restor- 

 ing them in his figures he makes the spire somewhat too high. The 

 coloration, " albida sub epidermide lutescente," the depressed last 

 whorl, " ultimus depressus," as well as the rapid expansion of the 

 latter, as shown in his figure 20, and the form of the mouth, all indi- 

 cate unmistakably that Montrouzier and Gassies correctly identified 

 the shell. 



B. sinistrorsus is said to occur fossil on the Isle of Pines and 

 Koutoumo islet ; but Gassies included ff. singularis Pfr. as a variety 

 of sinistrorsus, so the occurrence of the true sinistrorsa on the Isle of 

 Pines requires confirmation. 



Var. CASTANEOFASCIATA (Montrouzier). PI. 3, fig. 4. 



Decidedly larger than sinistrorsa, with the same form and number 

 of whorls ; gray-buff with a broad chestnut band at the periphery, 

 often faint, and fading at its edges into the ground-color ; spire red- 

 dish above; parietal callus thin. Alt. 12-14, diam. 11 ; long axis 

 of aperture 8.5, width 6 mill. Art Island (Gassies). 



Var. albidozonulata Gassies has been defined by the name, "whit- 

 ish zoned," only ; and is said by Gassies to agree with the typical 

 form in contour. It is from Mare, Loyalty Is. 



Just what form occurs on Ouvea Island is not known to me. The 

 supposed B. sinistrorsus from Lifu is D. lifuana. 



D. TURGIDDLA (Gassies). PI. 3, figs. 5, 6. 



Shell sinistral, openly umbilicate, turbinate-conic, thin, light 

 brown. Surface somewhat glossy, coarsely wrinkle-striate. Spire 

 conic, the outlines slightly concave ; whorls 5J, strongly convex, the 

 last depressed, rounded at the periphery. Aperture rounded-oval, 

 oblique, the peristome slightly expanded, both outer and columellar 

 margins arcuate, the latter dilated, the ends approaching and con- 

 nected by a thin callus. 



Alt. 5, diam. 3.5, length of aperture 2, width 2 mill. (Gassies).
