An exploring expedition which ascended Mount Maneao (the 

 Mount Dayman of earlier maps) brought back an interesting 

 collection of mollusca, comprising Neritina cornea, Nanina 

 cairni, Rhy sola fly ensis, Ckloritis rehsei, Papuina tayloriana, var 

 strabo, P. t. var katauensis, and the following novelty : — 



Papuina secans, n.sp. 

 (PL XXV., tigs. 8, 9.) 



Shell imperforate, trochiform, solid ; spire conic ; apex mamil- 

 lar, obtuse. Whorls 5, separated by an impressed suture, inflated 

 on their inner side, but on the outer compressed at the very sharp 

 keel, which runs around the whorls and disappears just behind 

 the aperture. Sculpture coarse, oblique growth lines decussated 

 and somewhat microscopically beaded by minute, close, waved, 

 spiral, impressed lines. Colour above pale purple, which fades 

 into white on reaching the keel of the last whorl ; the latter is 

 above the periphery painted by seven chestnut spiral bands, 

 opaque when seen by transmitted light ; behind the aperture these 

 bands broaden and merge together into a dark transverse stain ; 

 thinning out they fade away after ascending the shell for about 

 half a whorl. The base is encircled by five similar bands. Aper- 

 ture diagonal, abruptly and deeply descending. Lip intense black, 

 broadly reflected, beaked at the periphery, above the beak dinted 

 without and tuberculate within. Columella very broad, adherent 

 to the base, toothed on the inner edge. Margins united by a 

 narrow brown ridge of callus Fragments of a coarse (?) yellowish, 

 hydro[)l:anous epidermis appear on the last whorl. 



Maj. diam. 40, min. 33, alt. 22 mm. 



One example containing the animal vvas found, March, 1894, 

 at a height of from 1000 to 6000 ft. on Mount Maneao, B.N.G., 

 by the collectors of Sir William Macgregor. 



Type in the Australian Museum. 



Larger than any related form this species resembles tayloriana 

 in form and zeno in coloration ; other allies are naso and diomedes.
