3. magoides Melv. — Slightly flexuous in form, much like C. magus 



L., pinkish, with pink-brown blotching, suffusing most of the 

 surface. 



4. marmoricolor Melv. — A not uncommon form, in which the colour 



is black or dark-brown, and the white spaces arranged much as in 

 C. marmoreus L. or C. nocturnus L. ; spire, however, never 

 coronated. 



5. madagascariensis Sowb. — Conical, very finely reticulated. I hardly 



think this is a true species, though described as such by its 

 author. 



C. prselatus Hwass. — Always suffused and clouded with grey, 

 but distinct, I think, from all forms of C. omaria. 



C. elisse Kien. — Very closely reticulated with chocolate-brown, 

 so as to appear like a uniform brown surface with innumerable white 

 specks. Near C. racemosus Sowb. of the section Crocati. From 

 Madagascar. 



C. aulicus L. — The largest and boldest-marked species of the 

 genus, sometimes attaining a length of 15 to 17 cm. It is distin- 

 guished by its roundly oblong form, and spiral revolving striae ; 

 marking very bold, with scarce reticulations enclosing triangular 

 spaces. Colour deep chestnut-brown. 



1. propenudus Melv. — The marking becomes more scanty, leaving 

 a large tract of surface bare and white. 



C. auratllS Lam. — Very near the last, but constant in somewhat 

 greater compression of whorl, and difference of pattern, the reticula- 

 tions being all much smaller and dispersed in a zigzag manner. 



C. magnificus Reeve. — A very fine species, very constant in 

 elongate form, with somewhat conical, exceedingly obtuse spire and 

 apex, marked as in the body of the shell with extremely small irregular 

 reticulation ; the colour is pinkish, suffused with dark chestnut-brown. 

 From Luzon Island, Philippines. 



{b) Crocati. 



C. colubrinus Lam.— Yellow, with oblong white spots, or simple 

 reticulations. From Mauritius. 



C. crocatus Lam. — A very handsome orange-yellow conical 

 species, with white spots and markings, very few and far between, 

 and broader than long. Some examples are almost uniform yellow. 

 This species at first sight has almost less similitude to a Textile Cone 

 than any other. Native of Ceylon. 



C. racemosus Sowb. — Shell brownish-orange, solid, smooth ; 

 spire convex, with obscure reticulated brown and white marking lines, 

 and clusters of triangular white spots sparingly agglomerated. Unique 

 in my collection. Dredged in the Sandwich Islands.
