C. albinodiilosa, 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 snowy spots, shaded with fulvous brown ; 

 apex mammillate ; whorls six, elongate, convex, ver}^ 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. PI. 51, fig. 50. 



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

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

 conspicuously' and broadly 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.

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.

Shell ovate, smooth, yellowish, freckled or longitudinally waved 

 with chestnut; lip slightly thickened in the middle and dentate
