149. Selene vomer {Limmtus). 



Common at Panama. We have compared our specimens with others from 

 Florida and Jamaica, and find only individual differences. 



150. Chloroscombrus orqueta Jordan <i- Gilbert. 



Frequently taken in abundance. We have compared our specimens with the 

 original description (Jordan & Gilbert, 1882, 0, p. 646) and with specimens of 

 C. chrysia'us. 



The depth is very variable; in our most slender specimens the depth is 2% 

 in the length, while in the deepest specimen (of the same length) it is 2 J. 

 Between these extremes are all intermediate shapes. 



151. Trachinotus rhodopus Gill. 



Not abundant; eight specimens preserved, from l-') to 3G cm. in length. 



We have compared them with a single specimen of 7\ glaucus from Key 

 West. In addition to the less vertical snout noted by Dr. Gill, they diflcr in 

 having much longer, slenderer, and more numerous gill-rakers. The scales appear 

 to be smaller, and the dorsal and anal are probably slightly longer. 



The dorsal formula in seven sjiecimens is VI, I, 20, in one specimen VI, I, 19; 

 the anal in three specimens III, 19, in five specimens III, 18. The gill-rakers are 

 long and slender, and do not greatly taper in size from their base to their tips.
