200 Mr. Cosmo Melvill on the 



no closely connecting links. I am inclined to think C. 

 fiiscodentata and capensis may not be so far removed from 

 it after all ; and in C. bicallosa (Gray) with its large varieties, 

 ingloria and Aubiryaua, a slight resemblance may be 

 traced. 



The length is about 2}^ inches. Shell yellow-fawn, of 

 light texture, sprinkled with several large and small round 

 white spots over the dorsal surface ; on the base and over 

 the sides the teeth extend, which are bright orange, and 

 ridged. 



The localities given are China, N. S. Wales, Red Sea, 

 and New Britain, but I doubt these being substantiated, 

 except, perhaps, the first and last, this being recorded by 

 Mr. Hobson (1879). It is probable, from its thinness, that 

 it is a deep water species. 



The specimens known arc seven, or, at most, eight in 

 number, disposed as follow : — 



1 in National Collection (not very good), cf. Reeve, Conch. 



Icon., pi. viii., f 30. 



2 in Miss Saul's Collection. 



I formerly in Dr. Prevost's Collection, Alengon (sub- 

 sequently in M. Grasset's, of Algiers, and 

 now in the museum, Dijon, France). 



I in the Leyden Museum. 



I in Mr. J.C. Melvill's Collection, Prestwich (Fig. 7). This 

 specimen is one of the finest known, and was 

 formerly in the collection of Mr. Hugh Owen, 

 from whom it was procured through the 

 agency of Mr. R. Damon, of Weymouth. It 

 is the type figured by Sowerby. {TJies. 

 ConcJiyl.y pi. xvii., f 104, 105). 



I in Mus. Acad. Scient, Philadelphia, presented by Dr. 

 T. B. Wilson, a fine specimen. 



I believe Herr Paetel, of Berlin, also possesses one. 



N.B. — This species has been long known. Martini 

 (1769) figured it in his " Conchylien-Cabinet," Vol. I.
