104 AUSTRALIAN LAND SHELLS. 



intersected, columcllar margin entire, above appressed, 

 reflected, altogether closing the perforation, which, is con- 

 spicuous in young shells. Operculum thin, membranous, 

 narrow whorled.

 Dohrn, Pro. Zool. Soc, 1862, p. 183. 



Shell conically-ovate, rather thin, smooth, very glossy, pellucid, pale 

 reddish-horny ; suture impressed, narrowly margined ; whorls 5, 

 gradually increasing, slightly convex, last viewed in front more 

 than equalling j of the length ; aperture vertical, acutely, irregu- 

 larly and slightly obliquely ovate ; peristome thickened, moderately 

 expanded all round, slightly expanded and thickened at the colu- 

 mella. 



Length 0-28 ; breadth 0'15 ; aperture 0*11 long, of an inch. 



Habitat. Lizard Island, N. E. Coast of Australia, among dead leaves, 

 &c. Mac Gillivray. 



Br. Dohrn states the operculum to be "normal," by which, I presume, 

 he means similar to that of C. lubria, the only previotxsly known 

 species. Now, in that, both aperture and operculum are circular ; 

 here, they are ovate, and the lid is extremely thin, membraneous, 

 and, under the microscope, exhibits no circular lines of growth 

 whatever.

 aperture ovate, oval or semi-circular; peristome simple, 

 with distant and disjointed margins, straight or expanded.
