margins almost straight, tlie basal .slightly reflexed, columellar tri- 

 angulai'ly dilated above and slightly overhanging the umbilicus. 

 Diam. maj. 12-5, min. 11-25 mm. ; alt. 7-75 mm. 



Hal. — Moon Creek, Burnett River watershed, Queensland. 



Type in Dr. Cox's collection. At first I considered this to be 

 C. spinei, but that species appears to have a wider umbilicus and more 

 tumid whorls. A second specimen is immature, having only three 

 whorls completed. The warty tubercles probably bear hairs or bristles 

 when the shell is in fresh condition. 



Chloritis lanuginosa, n.sp. PI. XXI, Figs. 3, a-d. 



Shell narrowly umbilicated, depressed turbinate, dull corneous, 

 finely striated, with microscopic spirals under a densely, shortly pilose 

 cuticle, giving the shell a velvety appearance. Spire conoid, apex 

 prominent, suture rather deep. Whorls 4J, convex, increasing 

 regularly, the last a little widened and but slightly constricted behind 

 the peristome, shortly deflexed in front, obscurely angulated round the 

 narrow umbilicus. Aperture subovate, oblique, margins convergent, 

 united by a thin callus ; peristome thin, slightly expanded, not 

 reflexed ; margins evenly rounded, columellar triangularly dilated 

 above and reflexed over the umbilicus. Diam. maj. 11, min. 9-5 mm. ; 

 alt. 7'5mm. 



Mab. — Eidsvold, Queensland. 



Type in Dr. Cox's collection. This new species can only be 

 compared to C. hreoipila, but the whorls are less globose than in that 

 species, the spire is more elevated, the last whorl descends less in 

 front, and the conspicuous bristles of C. brevipila are here absent ; the 

 margins of the peristome are also more distant. Under a very strong 

 lens the quincuncial arrangement of the pili can with difficulty be 

 detected on the earlier whorls, but on the last it is imperceptible. 



Chloritis exilis, n.sp. PI. XXI, Figs. 4, a-d. 



Shell umbilicate, turbinate, very flnely and regularly striated, dull, 

 pale corneous, densely covered with minute soft, short, pale bristles 

 arranged in quincunx. Spire conoid, apex obtuse, suture rather deep. 

 "Whorls 5, convex, increasing rapidly, last dilated towards the mouth, 

 slightly descending in front, obtusely angulated round the narrow 

 umbilicus. Aperture suboval, oblique, margins convergent; peristome 

 white, scarcely thickened and narrowly reflexed, margins evenly 

 rounded, columellar triangularly dilated and less than half covering 

 the umbilicus. Diam. maj. 18, min. 15 mm.; alt. 13-5 mm. 



Hah. — Mount Dryander, Port Denison, Queensland. 



Type in Dr. Cox's collection. From C. Coxeni, its nearest ally, this 

 new species is distinguished by its smaller size, the less covered 

 umbilicus, and the densely crowded, finer, shorter, and paler bristles. 



From C. Bennetti, another ally, it differs in the narrower umbilicus, 

 and, although larger, in having one whorl less. A second specimen 

 of this new species is paler, and possesses half a whorl less than the 

 type. A third from Warroo, Port Curtis, is a little more elevated in 

 the spire, measuring alt. 15 mm.
