Specific Character. 



C. testd suprd, carinatd, fulvd, fasciis duobus albidis ornatd ; spiroe 

 brevis, maculatce, hasi depressd, anfractibus concavis sulcis duobus 

 insculptis, suturd alveatd ; basi granosd, purpurea. 



Shell above carinated, fulvous, with two whitish bands ; spire short, 

 spotted, the base depressed ; the whorls concave with two 

 depressed lines; suture channelled; base granulated, purple. 



1 HIS is a very beautiful, and, at the same time, very rare 

 shell ; it formerly belonged to Mrs. Angus, at whose sale 

 it passed into the cabinet of Mr. Dubois. Its general 

 appearance resembles very much that of C. Maldivus Lam. 

 known to our collectors by the name of the Spanish Admiral : 

 the spire will, however, at once distinguish it ; each volution 

 is strongly concave in the middle, in which part are two 

 or three delicate indented lines, very near each other, and 

 following the volutions ; the suture also is sufficiently open 

 to be termed channelled ; the spire is quite flattened at 

 the base, (forming a sharp ridge round the top of the body 

 whorl), and only prominent near the tip. In the Spanish 

 Admiral Cone, the spire is quite smooth, the whorls being 

 flat, and in all the specimens I have seen, (and they are 

 many), the suture is quite closed up, though Lamarck (pro- 

 bably mistaking the present shell) says, " spira canaliculata;" 

 the base, moreover, is narrowed, smooth, and black ; not 

 gibbous, granulated, (or striated,) and purple, as in this shell. 



A variety in my own cabinet presents some differences; 

 the base is but slightly granulated, and the tip not purple ; 

 these are, however, subordinate characters, and constitute 

 it only a variety. 



I shall take an early opportunity of pointing out the dif- 

 ferences between C. genera/is and Maldivus, two shells even 

 more likely to be mistaken for each other than those above- 

 mentioned.
