852. UHINOSCOPEUIS ANDRKij; (Liitkon). 



Head 3f ; depth U. D. about 10; A. about 20. Two caudal spots; a 

 posterolateral spot; 3 supra-anal spots forniiufx an obliiiue series; aual 

 Bpots about 5 or 6 + 9 or 10, the series slightly interrui>ted ; spots aloug

 Atlantic and Indian Ocean. (Liitken.) Common in the Gulf Stream 

 along our coasts with the preceding, of which Goode &, Bean think it may 

 be a sexual variation. (Named for Capt. A. T. Andreas, who collected 

 this and other oceanic fishes for the museum at Copenhagen.)

Nyclophus, Cocco, Giorn. Sicil., 44, 1829, (emended orthography of Miirlophiim). 



Body oblong, compressed, covered with cycloid scales, those in the 

 lateral line not much enlarged ; the caudal peduncle rather slender. Head 

 short, compressed, with limb of preopercnlum nearly vertical. Mouth 

 large, the jaws about equal ; premaxillaries long and slender ; niaxillaries 

 well developed. Snout more or less blunt and declivous. Teeth in villi- 

 form bands on jaws, palatines, pterygoids, and tongue. Eye large. Gill 

 rakers long and slender. Air bladder small. Dorsal fin entirely in front 

 of anal, overlapping it little or not at all; ventrals 8-rayed, under or 

 l)ut slightly in front of first dorsal rays ; ])ectorals well developed ; soft 

 dorsal slender. Precaudal photophores 2; stiperanals in two groups, 

 with one or two posterolaterals above the interval between them. Species 

 rathernumerous, widely distributed. (Name unexplained, usually derived 

 from vv^, night, and tf)wf , light ; hence altered by Cocco to Xycfopkus. 

 But we see no warrant for this sui)posed etymology. Kafinesque did not 

 know that the spots were luminous.)
