45. — POLYNEMUS C(ECUS. N. SP., PI. IX, fig. 1. 



D. 7 1/14, A. 2/i 5j L. lat. 83. 



Four pectoral appendages, the lowest little more than half the 

 length of the others, and all shorter than the pectoral fin ; 

 anal spines scarcely visible, colour silvery, becoming darker 

 towards the back ; all the rays of the pectoral and caudal fins 

 tipped with black, the latter long and much forked ; a dense 

 subopaque membrane covers each side of the head, through which 

 the eyes are dimly traceable. 



I have two specimens of this remarkable fish, each about 18 

 inches in length. Apart from the eye covering mentioned above, 

 a peculiarity I have not seen mentioned as having been observed 

 in any of the genus — this fish differs in many respects from the 

 descriptions of P. tetradactylus, the only species to which it can 

 be compared.
