HELIX-PAPUINA. 23 



c. Buffish-flesh-colored, with dots and two faint pink bands, one 

 above, one below, the periphery. 



d. The same ground color, with dark-brown bands. 



Figure 31, of PI. 17, is Pfeiffer's type. Fig. 1, PI. 6, is the 

 leucophcea of Cox. 



The largest specimen I have seen is figured on PI. 17, fig. 32. 



(3.) GROUP OF H. PILEUS. 



Narrowly, obliquely perforated ; elevated-conical; last whorl not 

 descending ; outer lip expanded ; surface smooth, obliquely striatu- 

 late. Differs from the group of H. meta only in distribution, the 

 present group being confined to the Moluccas and Papua. 



H. EUCHROES Pfeiffer. PI. 8, figs. 40, 41. 



Shell half-covered perforate, conical, rather solid, obliquely 

 irregularly striate, and very minutely granulate under a lens ; a lit- 

 tle shining, reddish-brown, ornamented with chestnut bands and a 

 wider white one below the suture. Spire regularly conical, lilac- 

 roseate above, apex rather acute. Whorls 7, moderately convex, 

 sensibly increasing, the last not descending, subrotund. Aperture 

 very oblique, subrhombic-lunar, grayish-white inside ; peristome 

 thin, its reverse chestnut colored, margins joined by a thin callus, the 

 right margin broadly expanded and subreflexed, basal somewhat 

 straightened, reflexed, forming an angle with the columellar margin, 

 which is vertical, slightly arcuate, triangularly dilated, half cover- 

 ing the perforation. Alt. 35, diam. 36 mill. (Pfr.') 



East Indies (Pfr.) ; Celebes (Rve.). 



H. euchroes PFR., Mai. Bl. i, 1854, p. 57 ; Monogr. iv, p. 256 ; 

 Novit. Conch, i. p. 2, t. 1, f. 7, 8. REEVE, Conch. Icon. f. 1346. 



One of the largest species of Papuina. The locality is not known. 

 Only one specimen has been placed on record, the figure of Reeve 

 and those in the Novitates being evidently drawn from the same 

 shell. It is apparently allied to H. pileus, but is larger, broader, and 

 differently colored. Compare also H. amphizona (pi. 8, figs. 52-54), 

 a species with solid, not perforated, axis, and different columella and 

 coloring, but of similar size. 



H. LENTA Pfeiffer. PI. 9, fig. 71. 



Rather openly perforate, trochiform, rather thin, very lightly 

 striate, grayish-flesh-colored or reddish-corneous, with opaque white 

 bands; spire elongate-conic, rather acute; whorls 7i, nearly flat,
