528 TYPES OF FISHES IN PARIS MUSEUM. 



7. Exocoetus gibbifrons. (Cuv. & Val., xix, 118, 1846.) 



Specimen .23"^ long, in fair condition. Atlantic Ocean : Dussumier. 



Second ray of pectoral simple, the first f length of the fin, which 

 reaches to middle of last dorsal ray; ventrals not reaching quite so 

 far. Insertion of ventrals midway between base of caudal (mesially) 

 and back part of eye. Eye 3 in hea<l. Head 4f in body. Depth, 6. 

 Anal short, with 8 rays. D. 1.12. Head a little more gibbous than in 

 other species, but not notably so; the interorbital area a little concave. 

 Dorsal, anal, and caudal plain. Pectorals becoming dusky backwards. 

 Ventrals posteriorly considerably dusky. 



This is the species correctly identified by Jordan and Meek as Ex- 



OCCETUS GIBBIFRONS. 



8. Exoccetus cyanoptenis. (Cuv. & Val., xix, 9, 1846.) 



One specimen in poor order ; rather stiff; .41™. Eio Janeiro : Hombron 

 & Jaquinot. 



Second ray of pectoral divided, the first f length of fin. Snout 

 pointed; interorbital area transversely concave. Snout 3 J in head. 

 Eye, 3|. Tail strong. Dorsal moderately high, its base one-third longer 

 than that of the rather short anal. D. 12 ; A. 11. Insertion of anal 

 considerably behind that of dorsal. Pectoral extending beyond tips of 

 last ray of dorsal and anal. Ventrals not quite to the base of the last 

 ray. Insertion of ventrals midway between base of caudal and edge 

 of preopercle. 



Fins all pale, except a round black blotch, about as large as eye, on 

 tips of middle dorsal rays. Ventrals white. 



This species is close to E. bahiensis, if, indeed, it is not the same. The 

 greater number (11 instead of 9 or 10) of anal rays alone separates it. 

 We may therefore provisionally regard U. cyanopterus with E. albidac- 

 tylus as a syuouym of ExoocBTUS bahiensis. 



9. EsocGBtas lineatus. (Cuv. & Val., xix., 92, 1846.) 



In fair condition. .43™. Gor^e : Bang. 



Second ray of pectoral divided, the first ray | length of longest. 

 Head rather pointed, the interorbital area flat. Snout 4 in head; eye 

 3^. Head 4| in length ; depth, 6J. Pectoral extending to base of last 

 anal ray, ventrals reaching nearly as far, their insertion midway be- 

 tween base of caudal and edge of preopercle. Anal short, its rays 1.10. 

 Dorsal 13, Dark lines on sides of back conspicuous only where scales 

 have been rubbed off, not forming an important feature of coloration. 

 Fins mostly dusky ; ventrals with faint dusky shades. Anal with an 

 obscure dark shade. Dorsal and caudal somewhat dusky, but un- 

 marked. 



This species is close to J/, heterurus, from which it is perhaps dis- 

 tinguished by the more backward insertion of its ventrals. It may 

 stand provisionally as ExoccETUS lineatus.
