Affinities. — C. kalimnae is undoubtedly closely allied to C. 

 placuiia, Tate,i from tlie Aldiiiga Cliffs and the Adelaide Bore, S. 

 Australia. It differs, however, from that species in its incrassate 

 type of shell, more evenly convex whorls, thicker carinate edfje and 

 sub-circular rather than circular outline. 



Distribution. — Bore 5, 155-159 feet. Bore 6, 114-150 feet. 

 Bore 8, 165-180 feet; 204-210 feet. Bpre 9, 254-256 feet; 256-263 

 feet; 263-273 feet; 315-325 feet. Bore 10. 186-190 feet; 254-296 

 feet.

 Soc. S. Austr., vol. xvii. pt. 327. 

 Observations. — Tate refers to this variety as " distinguished 

 simpl}' by its thick test and usually larger size, attaining to 20 

 mm. in length and width." The size of present specimen is con- 

 siderably greater than that given l)y Prof. Tate, having a length 

 of 50 mm. and a width of 52 nun. It was fortunately jammed 

 in the convolutions of the shell auger, and so escaped comminution. 

 This variety, crassa, has been found in both the lower and upper 

 beds of Muddy Creek (Balcombian and Kalimnan), and at Beau- 

 maris (Kalimnan). In the present case the associated fossils indi- 

 cate a Kalimnan age for the horizon of this variety. 

 Distribution. — Bore 10, 220 feet.
