108 PEOCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



shows the hair-points as minute tiibercles ; these disappear somewhat 

 suddenly near the termination of the third whorl. 



Chloritis Challengeri, n.sp. PL XIII, Figs. 5-bb. 



Shell umbilicated, depressed conoid, fragile, dark reddish-chestnut, 

 finely striated, shining under a velvety deciduous cuticle, decussated 

 with close microscopic spirals ; spire conoid, suture impressed, apex 

 raised, the nepiouic (1^) whorls finely granulated. Whorls 4^, 

 rounded above, subangulated above the periphery, slightly compressed 

 below, subangulated round the moderate umbilicus, which has one 

 or two spiral sulci inside, last whorl scarcely descending in front, 

 a little constricted behind the peristome. Aperture oblique, roundly 

 obovate ; margins approaching, evenly rounded ; peristome thin, rosy- 

 purplish, slightly expanded ; columellar margin triangularly dilated 

 and slightly overhanging the umbilicus. Diam. maj. 16, min. 14 mm.; 

 alt. 10 mm. 



Hah. — Queensland ("Challenger" Expedition). 



Type in the British Museum. 



Six specimens, one of them immature, showing the finely granulated 

 nepionic 1|- whorls very distinctly. The present species is allied to 

 C. manmeta^ being similar in shape, but the latter is more solid and 

 paler, and the whorls increase more slowly, while the granules, so 

 conspicuous in that shell, are lacking in the new species. C Porteri, 

 another allied form, has a narrower umbilicus and a more contracted 

 aperture ; the short, stiff, dark bristles still further differentiate that 

 species from both C. mansueta and C. Challengcri. 



Chlokitis ast^us, n.sp. PL XIII, Figs. 6-6c. 



Shell umbilicated, conoid, finely striated, whitish corneous, covered 

 with soft, short, very crowded, pale hairs, arranged in quincunx 

 (Fig. 6c); spire conoid, apex obtuse, suture impressed. Whorls 4, 

 convex, obtusely angulated round the narrow umbilicus; last whorl 

 slightly descending, then suddenly and shortly deflexed in front, 

 slightly dilated, then strongly gibbous and narrowly constricted 

 behind the peristome. Aperture subovate, oblique, margins convergent ; 

 peristome rosy-red, a little thickened, somewhat broadly expanded 

 and flattened, not reflexed ; upper and outer margins arcuate, basal 

 nearly straight, forming a slight angle with the columellar margin, 

 which ascends obliquely, is triangularly dilated, and slightly impinges 

 upon the obliquely excavated umbilicus, which has a short furrow 

 on the oblique portion. Diam. maj. 9-5, min. 8 mm. ; alt. 5'5 mm. 



Hah. — Cardwell, Queensland. 



Type in Colonel Eeddome's collection. 



Allied to C. hreripila, but the last whorl is more gibbous and 

 contracted behind the peristome, which is more expanded and flattened, 

 but not reflexed ; basal margin straight, and the hairs excessively 

 minute and close. 



Chloeitis Agamemnon, n.sp. PL XIII, Figs. 1-le. 



Shell narrowly umbilicated, depressed conoid, reddish corneous, 

 very finely striated, covered with excessively crowded and short
