(Albatross Exp.) in San Juan Lagoon, on the west coast of Mexico. The 

 larger specimen is much deeper in body than the other, and both differ 

 somewhat from the two specimens from Guaymas, the original types. 

 This species is very close to Centropomus pedimacula, but its scales are 

 larger in all the four known specimens than in any of the latter we have 

 seen, (grandis, great ; oculus, eye.) 



Centropomus yrandoculatm,* JENKINS <fe EVERMANN, Proc. U. S. Nat. Mus., 1888, 139, Guaymas. 

 (Type, No. 39630. Coll. Jenkins & Evermann.) 



1520. CENTROPOMUS CUYIERI, Bocourt. 



Head 3; depth 3f; eye 5. D. VIII-I, 10; A. Ill, 7; scales 9-51-14. 

 Maxillary reaching first third of eye ; preopercle with 2 short spines at 

 the angle, with smaller ones above and below. Third dorsal spine high, 

 about half head ; second anal spine long, but shorter than third, not 

 quite equal to greatest depth of body. Air bladder simple. Olivaceous ; 

 sides silvery ; lateral line black ; ventrals dusky at tip. Length 8 inches. 

 Haiti. (Vaillant & Bocourt.) Not seen by us. Apparently very close 

 to Centropomus pedimacula, but the scales apparently larger. Dr. Boulen- 

 ger refers the species to the synonymy of Centropomus pedimacula. 

 (Named for Georges Leopold Dagobert Cuvier.)

1521. CENTROPOMUS MEXICANUS,f Bocourt. 



Head 2f; depth 4; eye 4. D. VIII-I, 10; A. Ill, 6; scales 11-69-16. 

 Flanks compressed, parallel with each other; ventral outline nearly 

 straight, with an angle at the anal. Suborbital with 5 or 6 sharp teeth ; 

 preopercle with 2 teeth, larger than the others ; opercular lobe reaching 

 front of dorsal. Dorsal spines high, the third longest, 1? in depth of 

 body; second anal spine very long, much longer than third, equal to 



* The following is a description of the Guaymas types, slightly condensed from the origiaal: 

 Head 2%; depth 3f . D. VII-I, 10; A. Ill, 7; scales 8-52-10, 21 in front of the dorsal. Allied 

 to Centropomus pedimacula; the body compressed, the belly straight, the back somewhat elevated; 

 profile concave; nuchal region convex; maxillary reaching a vertical line through the pupil, 3 

 in head; snout 3 l /t to 3 in head; eye large, 5 in head; preorbital with small serrae on the pos- 

 terior portion, directed backward; preopercle with nearly equal, distinct teeth on the vertical 

 limb; a series of graduated teeth on the horizontal limb; a strong spine at the angle, and a 

 strong spine next above the angle, sometimes bifid; 2 flat spines at the angle of the anterior 

 ridge; suprascapula with 4 strong spines; opercular flap about reaching the vertical from the 

 front of the dorsal. Gill rakers 6 + 16, the longest as long as pupil. Dorsal spines strong, the 

 third being the highest and strongest, If in head; the fourth but little shorter, but more slen- 

 der, their tips, when depressed, scarcely reaching tips of ventrals; insertion of first dorsal spine 

 midway between tip of snout and last ray of second dorsal; fourth dorsal spine 2 in head; 

 second anal spine very strong, straight in one specimen, slightly curved in another, 1% in head; 

 third anal spine a little longer, but much more slender than the second anal and longer than 

 the third dorsal; caudal well forked; pectoral small, 2 in head, much smallerthan the ventrals; 

 ventrals with a strong spine; the spine nearly as long as the pectoral fin; soft rays of ventral as 

 long as third dorsal spine. Scales large on the sides; crowded in front of the dorsal. Color 

 white below; dusky above the lateral line, which is black and conspicuous; scales on back and 

 sides covered with numerous punctulations; first dorsal somewhat dusky, second lighter, colora- 

 tion of both due to fine punctulations; a large black blotch on the tips of the ventrals and anal; 

 membrane between second and third anal spines black. Jenkins & Evermann. 



fDr. Boulenger refers this species to the synonymy of Centropomus parallelm. This determina- 

 tion may be correct, but from Bocourt's description it would appear that Cenlropomus mexicamis 

 had a dark lateral line and larger scales than C. parallelus,
