2620. GNATHYPOPS MAXILLOSA (Poey). 



Head 3$; depth 4$. D. VIII, 17; A. II, 13; scales 65. Body moder- 

 ately compressed; head not very large; maxillary truncate behind, 

 extending hehind eye for a distance for about f- diameter of eye, its length 

 If in head; eye 3f in head. Teeth conical, curved, well separated, mostly 

 in a single series; no teeth on vomer. Fins moderate; dorsal continuous, 

 its spines slender; caudal short, its length f head. Color grayish olive, 

 with 7 irregular A-shaped bars of darker, everywhere much marbled 

 and variegated; fins all similarly marked, the ventrals dusky, the dorsal 

 with a dusky blotch in front. Cuba, north to Florida, from which local- 

 ity the specimen here described was taken. Evidently very close to 

 the Brazilian species G. cuvieri, the eye perhaps smaller. According 

 to Poey. Gnathypops maxillosa has the eye 4 in head ; D. VIII, 18 ; A. II, 15 ; 

 2 teeth on vomer; spinous dorsal lower than soft dorsal; body covered 

 with large yellow spots on a ground color of clear brown; 6 brown cross 

 bands reaching middle of dorsal, which is variegated with yellow and 

 reddish, as is the anal ; maxillary yellowish on its posterior border, the 

 middle blackish; other spots on the jaws; ventrals, pectoral, and caudal 

 yellowish, the ventrals finely spotted with brown, the caudal with 5 

 brown bands; base of pectorals with dark spots. Vertebrae 10 + 17 = 27.

2621. GNATHYPOPS MACROPS (Poey). 



Head 3 in total (with caudal?) ; depth about 4. D. XI, 16; A. II, 15 or 

 16; scales 100. Eye 3| in head; maxillary extending beyond eye of a 

 diameter, 5| in head; vomer with 6 conical teeth. Color (faded in the 

 type) reddish olive, with round, yellowish spots and vestiges of vertical 

 bauds; dorsal and anal plain, pectorals with brown bands; jaws not 

 spotted with brown and white. Coast of Cuba (Poey); known from 1 

 specimen 132 mm. long; not seen by us. According to Poey, it may not 

 be distinct from G. maxillosa, which in turn may possibly be the female 

 of Opisthognathus macrognathum. This species may also be identical with 

 the Brazilian species Gnathypops cutieri,* but the latter has a dorsal ocel- 

 lus and apparently larger scales, (^anpoc,, large; ooif>, eye.)

* Gnathypops cuvieri (Valenciennes). Head 3; depth 4J; eye 3 in head. D. X, 18; 

 A. II, 16; scales 70. Maxillary reaching beyond the verticarfrom posterior margin of 

 orbit, 1J in head; eye 3 in head, dorsal fin not notched. Olivaceous; a large dark-blue 

 ovate ocellate spot between the fourth and eighth dorsal spines; dorsal and anal mottled, 

 the edge dusky posteriorly; caudal with 3 dark-bluish bands. Eahia (Valenciennes). 

 (Named for Georges Dagobert Cuvier.)
