48 PKOCEEDINGS OF THE MALACOLOGICAL SOCIEXr. 



Chloritis exigua, n.sp. PI. IV, Figs. 8-8c. 



Shell widely umbilicated, depressed, dark tawny, lightly striated, 

 densely pitted. Spire subplane, suture deep, apex a little raised. 

 "Whorls 4^, increasing rather slowly, rather tumid above, rounded at 

 the periphery, obtusely angulated round the wide funnel-shaped 

 umbilicus ; last whorl shortly deflected in front. Aperture sub- 

 circular, little oblique, dark within ; margins a little approaching ; 

 peristome rosy fuscous, a little thickened, expanded and reflexed ; 

 upper margin ascending a little at first, then sloping down ; outer, 

 basal, and columellar arcuate, the latter scarcely dilated. Diam. maj. 

 12, min. 105 mm. ; alt. 7*5 mm. 



Hah. — New Ireland. 



Type in my collection. 



A specimen which could not be referred to either of the preceding 

 species has lain in my collection for years. It is smaller and darker 

 than any of its allies, has the apex raised, and, compared with 

 C. conjimcta, it has a more rounded aperture, and the hair-scars are 

 more crowded. 



Chloritis Cumingi, n.sp. PI. V, Figs. \-\a. 



Shell widely umbilicated, convex - conoid, solid, lightly striate, j 

 reddish-brown. Spire conoid, suture margined, apex obtuse. Whorls 

 6, convex, increasing regularly, with fine spiral sculpture under 

 a deciduous cuticle, the apical whorl minutely pitted, the last dilated 

 towards the mouth, shortly descending in front, its latter half scoi-ed 

 with about six straight, obliquely descending furrows. Aperture 

 obovate, oblique ; peristome white, thickened and reflected, margins 

 subparallel, converging near the body-whorl, united by a thin whitish 

 callus ; columellar margin ascending at an obtuse angle beyond the 

 umbilical angulation. Diam. maj. 56, min. 45 mm. ; alt. 36 mm. 



Hah. — New Guinea (Mus. Cuming). 



Type in the British Museum. 



This new species is more elevated in the spire and more angulated 

 than C. rnhra, Albers. Prom C. concisa, Per., it differs in the shorter 

 furrows which are confined to the last whorl. I associate with this 

 handsome and striking species the name of the celebrated collector, 

 Hugh Cuming, of whose collection the three shells, on which I base 

 the species, formed part. They were labelled C. conciso, Per., until 

 Mr. Ponsonby pointed out that they could not be referred to that 

 species, and Mr. Smith, with his usual courtesy, now afforded me an 

 opportunity of naming and describing them.
