4. Caranx litgubris* Poey. (:N^o. 28^375 U. S. Nat. Mus.) 



Body obloug-ovate, compressed, deep, the back elevated, but not 

 arched. Profile gibbous from the occiput forward to above eye, thence 

 straight and steep at a considerable angle to a point in front of nostrils, 

 whence the snout again projects at a strong angle. Outline of back 

 nearly straight from the occiput to the front of the second dorsal, thence 

 declining regularly to the caudal peduncle. Ventral outline nearly 

 straight from the lower jaw to the origin of the anal, the base of which 

 is i^laced at a similar angle to that of the soft dorsal. 



Head large, very deep, deeper than long; occipital ridge not sharp. 

 Mouth large, the broad maxillary reaching to opposite front of pupil. 

 Lower jaw strong, the chin ]>rojecting when the mouth is closed. Teeth 

 in the upper jaw in a narrow villiform baud, with an outer series of 

 larger, conical teeth, six to eight in number on each side, subequal and 

 regularl}^ arranged. Lower jaw with a single series of teeth similar 

 to the larger teeth of the upper jaw, a few smaller teeth intermixed 

 with them. No differentiated canine teeth. Villiform teeth on vomer, 

 palatines, and tongue. Gill-rakers rather long, close-set, three-fifths 

 diameter of eye. Eye large, with a distinct adipose eyelid, its diameter 

 equal to that of the broad preorbital, which is wider than the maxillary, 

 4J times in length of head. 



Cheeks closely scaled; opercles mostly naked below; a few scales on 

 subopercle and interopercle. Scales on body not very small; breast 

 . closely scaled. Lateral line with a moderate curve anteriorl.y, becoming 

 straight at front of anal ; the length of the arch being less than two-thirds 

 that of the straight x>art; greatest depth of the arch about one-fifth its 

 length. Armature of lateral line beginning at the curve; the plates 

 rather large, very broad, twenty-eight in number. Fins with very few 

 scales or none. 



Spinous dorsal moderate, the spines rather strong, its last spine stout 

 and free, nearly horizontal. Second dorsal falcate, the longest rays more 

 than half the length of its base. Posterior part of the fin rather low, 

 rising well above its low basal sheath of scales which terminates near 

 the middle of the fin ; anal similar to soft dorsal, its anterior rays more 

 than half the base of the fin. Free anal spines moderate. Caudal lobes 

 rather broad, equal, not very long, the upper as long as from snout to edge 

 of opercle; depth of the fin from tip to tip, about equal to depth of head. 

 Ventral fins short, not filamentous, as long as from snout to end of max- 

 illary. Pectoral extremely long, falcate, reaching to the tenth plate of 

 the lateral line, or about to seventh anal ray, its length 2^ in that of 

 body, less than than the greatest depth of the body.
