M1TRELLA. 137 



dinally obscurely ribbed, the ribs usually obsolete, or surface 

 sometimes quite smooth; yellowish, necked with white, especially 

 on the ribs or nodules, with three necklace-like rows of small 



chestnut spots. Length, 8-9 mill. 



Seychelles, Mauritius. 



C. albinodidosa, Gaskoin, is a synonym, but the only figure of 

 it, in Reeve's Iconica, is not at all characteristic, and resembles 

 closely the next species. 



C. LEGRANDI, Tenison-Woods. PI. 51, fig. 49. 



Shell small, subulate, thin, shining chestnut, girdled at the 

 suture with a band of sno.wy spots, shaded with fulvous brown ; 

 apex mammillate ; whorls six, elongate, convex, very finely trans- 

 versely lined ; aperture elongately ovate ; outer lip thin, simple. 



L. 7 '5, diam. 2 mill. Tasmania. 



My figure is drawn from one of the type specimens ; it is a 

 smaller, narrower shell than the last species. 



C. XAVIERIANA, Tenison-Woods. PL 51, fig. 50. 



Shell elongated fusiform, smooth, striated at the base ; whorls 

 eight, rather flattened ; lip thick, plicate within; orange-brown, 

 conspicuously and broadty maculated with chestnut which under 

 the lens is sometimes seen to be flecked with white. 



L. 12, diam. 4 mill. Tasmania. 



Figured from the type specimen, through the kindness of Mr. 

 C. E. Beddome of Hobart Town. 



C. ALBA, Petterd. 



Shell attenuately fusiform, shining, white faintly tinged with 

 chestnut, regularly transversely striate all over ; whorls six, flatly 

 convex ; aperture narrowly ovate, inner portion faintly thickened, 



outer lip thin. L. 7, diam. 3 mill. 



Blackmarfs Bay, Tasmania. 



Unfigured. " The regular transverse striae is a character by 

 which it can be easily recognized." 



C. CHOAVA, Reeve. PL 51, fig. 51. 



Shell ovate, smooth, yellowish, freckled or longitudinally waved 

 with chestnut ; lip slightly thickened in the middle and dentate 



within. Length, 6 mill.
