NEW SPECIES OF LAND-SHELLS FROM NEW GUINEA. 
By H. B. Presron, F.Z.S., etc. 
Read 8th November, 1901, and 10th January, 1902. 
1. Macrocutamys Papurnsis, n.sp. Fig. I. 
Shell zonitiform, hyaline, pale horn colour, slightly pinkish towards 
the mouth; whorls five, somewhat rounded, elaborately sculptured 
with growth-striz, and with close-set, very fine, and slightly waved 
spiral lines ; suture impressed, closely but strongly malleated ; mouth 
oblique; peristome simple, forming a slight fold nearly encircling the 
umbilicus; the latter is fairly deep and very narrow. Alt. 14 mm.; 
diam. maj. 23, min. 19 mm. 
Hab.—Northern coast of British New Guinea. 
The type is in the British Museum. 
This species is of a very beautiful form; and its sculpture readily 
separates it from the few species hitherto known from the Papuan 
region. 
2. CHLoriris (SuLcoBasIs) GLoposa, n.sp. Fig. IV. 
Shell globose; spire rather elevated; colour dark rufous; whorls 
five, rounded, coarsely striated with lines of growth; mouth oblique, 
roundly ovate, contracted above; peristome reflected, white tinged 
with lilac ; umbilicus very deep, partly concealed by the reflexed lip. 
Alt. 24mm.; diam. maj. 30, min. 25mm. Mouth (inside measure- 
ment), diam. 14, alt. 13 mm. 
Hab.—Northern coast of British New Guinea. 
The type is in the British Museum. 
The nearest ally of this shell appears to be Chlorrtis stirophora 
(Smith), from which it differs in the following particulars: its more 
elevated and rounded form, the traces of keel being much less 
apparent and the whorls more convex; its darker colour, more rounded 
and more oblique mouth, and in the much greater extension of the 
columella over the umbilicus. 
3. Cutoriris (SuLcopasis) strropHorA (Smith), 
var. CoLLINGWooDENSIS, n.var. Fig. V. 
This variety, of which I have nine specimens before me, differs 
from the type mainly in its small size; but it is also more depressed 
and less openly umbilicated. Alt. 14mm.; diam. maj. 25, min, 21 mm. 
Hab.—Collingwood Bay, B.N.G. 
The type is in the British Museum.
