Of this most singular species I never procured more than one specimen, 

 caught on the coast of Palermo. Its size, colour, and general appearance, 

 was that of the last, even to the redspoton the dorsal, but the tail was much 

 thicker, and the caudal fin, as here represented, {fig. 127. f). Had the rays 

 of this fin been the same in number as that of C. novemradiata, a suspicion 

 might have been entertained that this had been a mutilated specimen, but 

 the rays were actually only six, and the margin of the membrane quite en- 

 tire. Added to this, the base of the ventral is under the second, and not, 

 as in that, under the first dorsal ray ; while the pectoral fin, instead of not 

 reaching to the vent, terminates exactly in a line with it. 



CEPOLA Gigas. 



Ventral fin exactly beneath the pectoral, but longer_, 



and reaching to the anus ; anal fin commencing on a 



line between the eighth and ninth dorsal ray j caudal 



fin ? 



In the British Museum. 



The only specimen existing in our national collection is, unfortunately, 

 deprived of its caudal fin. The unusual length, however, of the ventrals, 

 which reach to the aperture of the anus, seems to be a positive mark of 

 distinction, particularly as this fin is longer than the pectorals, a dispropor- 

 tion which I have not observed in any other. The colours are completely 

 gone, and the specimen, apparently, is very old. It is the largest of any 

 ■Cepola in that collection; but I omitted, unluckily, to take the measure- 

 ments.

siderably behind the ventral fin, which commences in 

 a line with the first dorsal ray. (^fig^ 127. «•) 

 In Mr. Yarrell's collection (the Cepola rubescens * of Risso. ) 



A finely grown and 

 well dried specimen 

 of this Cepola was 

 obligingly commu- 

 nicated to me by 

 Mr.Yarrell, It shows 

 a great peculiari- 

 ty in the situation 

 of the ventral fin, 

 which is placed so 

 much in advance. 



f At^^. 127. e, IS an exact copy of the tail of Cuvier's C. rubescens, which 

 it is easy to perceive does not agree with any one of the species here de- 

 scnbed ; not only in the number of the rays, but also in their being repre- 

 sented as extending beyond the membrane
