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

 larger specimen is mucli 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 Ceniropomus pcdimacula, but its scales are 

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

 seen. (<jf?'aHf/(s, great ; oculiis, eye.) 



Centropomus gra7idociilatiis,* Jenkins & Evermann, Proc. U. S. Nat. Mu8., 1888, 139, Guaymas. 

 (Type, No. 39C30. Coll. Jenkins & Evermann.) 



1520. CENTROPOMUS CUTIERI, Bocourt. 



Head 3; depth 3|; eye 5. D. VlII-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 pedbnacula^ but the scales apparently larger. Dr. Boulen- 

 ger refers the species to the synonymy of Centropomus pedbnacula. 

 (Named for Georges Leopold Dagobert Cnvier.)

1521, CENTROPOMUS MEXICANUS,t Bocourt. 



Head 2f; depth 4; eye 4. D. VIII-I, 10; A; III, 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 typos, slightly condensed from the original: 

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

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

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

 in head; snout 3' ^ to 3^ iu head; eye large, 5 in head; preorbital with small serr.T? on the pos- 

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

 limb; a seiies of graduated teeth on the hcjrizoutal limb; a strong spine at the angle, and a 

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

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

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

 third being the highest and strongest, 1^ 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, l"^ in head; 

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

 the third dorsal; caudal well fdfkcd; pectoral small, 2J in head, much smallcrthau 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 punctulatioiis; first dorsal somewhat diisky, second lighter, colora- 

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

 membrane between second and third anal spines black. — Jenkins <t Ecemiaun. 



fDr. Boulenger refers this species to the synonymy of Ctntropotii us parallehis. This determina- 

 tion may be correct, but from Bocourt's description it would apjtear that Ceniropomus mexicantia 

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