new Species of Ihlicoida. 317 



not acute at junction of upper and basal margins. The oblique 

 sculpture is similar to that of P. Fergusoni, Ad., but P. dense- 

 striata has not the spiral striie of that species. The specimens 

 before me vary in tlicir proportions, some being narrower than 

 tlie type and more acutely carlnate at the peripliery, others 

 are wider with the peristome more rounded at outer margin. 



Papuina humilis^ sp. n. 



Shell broadly conical, solid, imperforate, pale yellow, some- 

 times with a faint lighter-coloured spiral band situated on 

 the periphery of body-whorl, apex prominent ; whorls 5|, 

 moderately convex, regularly increasing, with ratiier distinct 

 oblique lines of growth, last obsoletely carinate in front only, 

 slightly descending ; aperture subovate, very oblique, white 

 within ; peristome thickened, expanded and somewhat re- 

 flected, white, columellar margin oblique with a slight angle 

 where it joins the basal margin, basal and outer margins 

 curved, margins joined by a very thin transparent callus, the 

 latter and the parietal wall covered with microscopic granules, 

 columellar margin triangularly broadly expanded at point of 

 insertion.

Ilah. Nusa, New Mecklenburg Island {C. Wahnes). 



This species resembles P. coniformis^ Fer., in the form of 

 its spire, but that species is narrower in proportion to its 

 height, and, moreover, has conspicuous decussated sculpture. 

 From P. Chancel, Cox, it can be distinguished by its smaller 

 size, flatter form, and more convex whorls. Readily separated 

 from P. Boyerij Fis. & Bern., by the absence of the reticu- 

 lated sculpture and its less angular form. 



Papuina j ucundn y sp. n. 



Shell depressed conic, somewhat thin, imperforate, white, 

 covered by a golden-yellow periostracum with oblique broken 

 zigzag markings of a lighter shade, compressed and acutely 

 carinate at the periphery of last whorl ; whorls 4^, the upper 

 convex, the last concave at lower margin, convex above, first 

 three whorls white, smooth, others and underside of body- 

 whorl covered with minute rugose striae which cross the lines 

 of growth in an obliquely spiral direction ; aperture light 

 within, the exterior markings showing through ; peristome 

 very slightly thickened, black, somewhat expanded at the 

 lower part of basal and right margins, basal margin curved, 

 right upper margin bent inwards. 



Maj. diam. 23, alt. 14 millim.
