 fin seventy-two rays, in the pectoral twelve, the first very 

 short; on the under side this fin is scarcely half as large as 

 that which is above. Kays of the dorsal and anal fins bent 

 in a curve backward towards their extremities. In the caudal 

 fin eighteen rays, of which the middlemost are much the 

 longest. The colour had probably faded through the" length 

 of time these examples had been out of water ; the one described 

 was pale brown without spots, m the other was a tinge of 

 pink. Along the rays of the dorsal and anal fins was a series 

 of slight scales.
