GUDE : ON NEW SPECIES OF CHLORITIS. 231 



Chlokitis cognata, n.sp. PI, XXI, Figs. 5, a-d. 



Shell moderately umbilicate, globose turbinate, finely regularly 

 striated, whitish corneous, covered with crowded hair-scars arranged 

 in quincunx. Spire conoid, apex obtuse, suture deep, almost 

 channelled. "Whorls nearly 5, convex, increasing regularly, the last 

 rather suddenly, shortly deflexed in front, widening towards the 

 mouth and slightly constricted behind the peristome, subangulated 

 round the slightly excavated umbilicus. Aperture subovate, oblique, 

 margins approaching ; peristome white, a little thickened, and reflexed ; 

 upper margin arcuate, outer and basal rounded, columellar triangularly 

 dilated above and a little overhanging the umbilicus. Diam. maj. 

 I4"5, min. 12 mm.; alt. 10 mm. 



Hah. — Olsen's Caves, Eockhampton, Queensland. 



Type in Dr. Cox's collection. Somewhat similar in shape to 

 C. exilis, but more depressed and with the hair-scars less crowded ; the 

 margins of the peristome are more approaching, and the umbilicus is 

 a little wider and more excavated. 



Chlokitis mickomphala, n.sp. PL XXI, Figs. 6, a-d. 



Shell narrowly umbilicate, globosely turbinate, finely irregularly 

 striated and decussated with wavy incised spirals, dark corneous above, 

 paler beneath. Spire conical, apex obtuse, suture deep. Whorls 4, 

 globose, increasing rapidly, the last dilated towards the mouth, 

 descending suddenly and deeply in front, obscurely angulated round 

 the narrow deep umbilicus. Aperture suboval, oblique, margins 

 approaching, united by a thin callus; peristome white, a little 

 thickened and reflexed, margins evenly rounded, columellar margin 

 broadly triangularly dilated, more than half covering the umbilicus. 

 Diam. maj. 21-5, min. 18 mm. ; alt. 17 mm. 



Hah. — Barrier Range, North-West Australia. 



Type in Dr. Cox's collection. The only species to be compared with 

 C. micromphala is C. Blachnani, but the globose whorls, the broader 

 base, the more dilated last whorl, the more approximate margins of the 

 peristome, and the absence of hair-scars at once separate the new 

 species from its ally; the more broadly dilated columellar margin of 

 the peristome and the more covered umbilicus are also differentiating 

 characters. 



Chloeitis Poorei, n.sp. PI. XXI, Figs. 7, a-d. 



Shell moderately umbilicate, globose, thin, pale ochreous, a little 

 shining, irregularly striated, very densely covered with minute hair- 

 scars arranged in quincunx. Spire conical, apex obtuse, suture 

 channelled. Whorls 4-J, increasing regularly, tumid, shouldered near 

 the suture, somewhat compressed at the periphery, obtusely angulated 

 round the deep umbilicus, which is slightly excavated ; last whorl 

 slightly dilated towards the mouth, scarcely descending in front. 

 Aperture subcircular, oblique, margins convergent; peristome pale 

 fulvous, thin, a little expanded ; margins evenly rounded, columellar 

 triangularly dilated and reflexed, covering half the umbilicus, Diam. 

 maj. 12-5, min. 10'5mm. ; alt. 9*5 mm.
