Nematislins, Gill, Proc. Ac. Nat. Sci. Thila., 1862, 258, {pectoral is). 



ff Scriolophus, * GuicuExoT, Mem. Soc. Sci. Nat. Cherbours;, xui, 90, 1S(;8. (caranyoides). 



This genus is allied to Scriola, from which it differs notably in the devel- 

 opment of the spintius dorsal and the pectoral (ins, the dorsal being com- 

 posed of 8 very long filamentous spines, the pectorals being falcate, 

 acuminate, and nearly twice as long as the ventrals. The lateral line is 

 nearly straight and is not keeled on the caudal peduncle. Ventrals 1, 5, 

 the inner ray much branched to the base so that the number of rays appears 

 much greater than it really is. One species known ; a large fish of an 

 imposing appearance. (i7///a, thread; tcrr/op, sail.) 



1283. NEMATISTIUS PECTORALIS, Gill. 

 (Pez i)E Gallo ; Pap.\gallo.) 



Head 31 ; depth 2? ; eye 5 in head in young ; snout 4. D. VIIl-I, 27 or 

 28; A. 1,17; scales 119. Body oblong, compressed; caudal peduncle 

 slender. Scales very small and inconspicuous ; lateral line simple and 

 unarmed. Mouth rather large, very oblique, the cleft continued under 

 the eyes. Teeth villiform, small. Dorsal fins 2, folding into a deep sheath, 

 the first with 8 long filamentous spines, the second low and elongate ; 

 anal fin low, long, but shorter than second dorsal; pectoral fin very long 

 and falcate. Color plumbeous on the back and opercles ; sides golden ; 

 an indigo-blue cross baud on the snout, another on the forehead, a third 

 baud from nape to subopercles ; a broad iudigo band from first dorsal spine 

 to near vent ; a curved band from sixth dorsal spine downward and across 

 to base of upper caudal rays ; dorsal spines banded with alternate blue 

 black and white; lower half of pectoral black. Length of adult 4 feet 

 or more. Gulf of California to Panama, generally common ; one of the 

 most stately fishes in our waters, its long rays brightly colored, giving a 

 striking appearance. Recorded from Cape San Lucas, Guaymas, Piche- 

 luogo, Mazatlan, Magdalena Bay and Panama, {pectoralis, pertaining

Family CXXV. CARANGID^E.t 

 (The Pampanos.) 



Body more or less compressed and often elevated, sometimes naked, or 

 more usually covered with small, thin, cycloid scales. Head compressed, 



* Seriolophii/i, accordins to Guichenot, is distinguished froui Seriola in having the dorsal spines 

 much prolonged and tiliform; all the opercular boues covered with scales. D. VIII-I, 30; .\. II,
