XV. — Description of a New Species of Cepha- 
lus, winch it is proposed to name Cephalus 
CocHERANi, Cochrane's Sunfish. 
By Dr T. S. Traill of Liverpool. 
(Read \ 6th April 1825.) 
Char. Specif. Cephalus corpore elongato, truncato subargenteo, 
spinis vel tuherculis carenti. 
Sunfish with elongated but tmncatedj sub-argenteous body, desti- 
tute of spines or tubercles. 
This small species is sufficiently characterized by its form, 
as a sunfish ; and appears to diifer from any described by 
systematic ichthyologists, so much as to entitle it to be reckon- 
ed a new species. It was found in the stomach of a Bonito 
or Alhacore *, which was caught on the 17th of May 1822, 
in Lat. 18° S. Long. 81° W., by a sailor on board of the 
O'Higgins, Lord Cochrane's flag-ship. On this account I 
have proposed the name in honour of that gallant officer. 
A correct drawing, the exact size of the original, was 
made by a young Chileno then on board ; and this having 
been presented to me by a gentleman, then acting as his 
Lordship's secretary, it accompanies the description of the 
fish. See Plate VI. Fig. 2. 
* Either Scomber Pelamis or Scomber Thynnus,
