2i6 Mr. Cosmo Melvill oh the 



faint trace of transverse band on the larger specimen, under- 

 side with dentition as in Bregeriana, teeth about twenty-one 

 on each Hp, a basal central patch of deep red-grey. The 

 small white pitting is in these three shells extremely charac- 

 teristic, and although they may be a distinct species, yet 

 there is no doubt they impinge very closely on C. Bi^egeriana^ 



C. fijnbriata (Gmel.). Reeve, f i8, f 92. Sow., T. C, 

 pl.xxxii. ,f 387-391. This species, always extremely variable,, 

 is known mainly by the violet painting of its extremities. 



{a) C. viicrodo7i (Gray) I consider but a variety, w^ith 

 very beautifully minute teeth, extremities violet.^' 



ib) iinifasciata (Mighels). This variety is thus charac- 

 terised by Mr. A. Garrett (/, of Conch., 1879, p. 120 : — 

 " Larger (than C. fimbriata), teeth coarser, less numerous, 

 and the ground colour, which is of a more bluish tint, marked 

 with a more or less broken, transverse, yellowish-brown 

 band. Both species have the terminal pink spots as well as 

 the profusion of small yellow dots." 



{c) macula (Adams), sp. Sow., T. C, 379 — 381, more pyri- 

 form than the type, with the extremities dark purple brown. 



{d) Cholmo7ideleyi {yd.x. nov.), Sow., T. C, pi. xxxii., f. 387,, 

 388. This magnificent form is very uncommon, there is a 

 good specimen, formerly in the collection of Reginald Chol- 

 mondeley, Esq., now in the Museum of the Owens College, 

 Manchester. Length i J^ inch, breadth y^ inch. Native of 

 Australia. The main distinction of this variety is its size, 

 and greater dorsal effusion. Mr. J. M. Williams possesses 

 Mr. Hugh Owen's original specimens ; almost as large as the 

 type now figured, pi. ii., f 15. 



C. fabida (Kiener) \ cf. Sowb. Thes. Conch., pi. xxxii.^ 



G. fclina (Gmelin) J f. 393-395. 



* The other variety of C. Walkej-i^ {/>), amahilis (Jousseaume), is said by 

 the author to differ in the more produced extremities, which are a little re- 

 curved, narrow bands dorsally, and only the inner lip purple tinted. I have 

 never seen this. It is figured in Try on. Man. Conch. Cyprcea, pi. xiv, f. i, 2. 



'' The Rev. R. B. Watson (Rep. on Gast. Challenger Expedition, Vol. X\'., 

 p. 424) considers this a good species, so do Messrs. Roberts, Reeve, and 

 Sowerby.
