4 PEOCEEDINGS OF UNITED STATES NATIONAL MUSEUM. 



Id the young fish, under the length of two or three feet, the sides are 

 covered with round, irregular spots, of rather dirty yellow (jaune un peu 

 sale). 



Ouvier described a specimen which weighed twenty-two pounds ; at 

 that size, the fish is still young, and retains its yellow spots. 



Those ordinarily taken range in weight from twelve to twenty-five 

 pounds, though they reach the weight of one hundred pounds. I have 

 seen one which measured 285 mm .

Differential Characters. — The first dorsal has seventeen spines and the 

 spot upon its anterior portion. The lateral bands and spots are persistent 

 through life. 



The teeth are f£ in a specimen of moderate size. In the upper jaw, the 

 median teeth are the larger; in the lower, their size is more nearly equal. 



The back is bluish, as are also the top of the head, the second dorsal 

 and its finlets, the caudal, and the pectorals. The first dorsal is white, 

 having in front a spot of deep-blue, which is prolonged far back upon 

 the upper edge of the fin. The anal and the ventrals are white. The 

 sides are sky-blue, with silvery lustre ; the belly is white, with a bluish 

 tinge. The sides are marked with broken longitudinal bands and round 

 spots; these bands and spots are yellow, more or less golden, and with 

 a reddish tint. 



The ordinary size is about twelve pounds, though they sometimes 

 reach tbe weight of twenty. 



Cybium acervum, Cuv. & Yal. 



Cybium acervum, Cuvier & Valenciennes, op. cit., p. 186. 

 The specimens described by Cuvier were of five pounds weight. He 

 chums to have received specimens from Martinique, from San to Domingo, 

 and from Cuba, those from the latter place sent by me. I can only say 

 that 1 have not been able to find this species, and that I have not 

 included it in my manuscript " Ichthyologies 



According to Cuvier, it has seventeen spines in the first dorsal, and 

 also the black spot. The body is immaculate, even in the specimens of 

 five pounds weight.
