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 behind eye for a distance for about | diameter of eye, its length 

 If in head; eye 3j 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. Ccdor 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. ctirieri, the eye perhaps smaller. According 

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

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

 Avith large yellow s])ots on a ground color of clear brown ; 6 brown cross 

 liands reaching middle of dorsal, -which is variegated with yeUow and 

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

 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. Yertebnu 10 + 17 ^ 27.

2621. GNATHYPOPS MACROPS (Poey). 



Head 31 in total (with caudal?) ; depth about 44. D. XI, 16; A. II, 15 or 

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

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

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

 bands; 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 Opistliognailnis macrognaihiim. This species may also be identical with 

 the Brazilian species Gnathijpops cuvUri,* but the latter has a dorsal ocel- 

 lus and apparently larger scales, {/tanpoi, large; ooip, eye.)

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

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

 orbit, IJ in head; eye 3i in head, dorsal'fin hot notched. Olivaceous; a large dark-blue
