deep, compressed, with flattened parallel sides Preorbital sbaiply ser- 

 rate ; preopercle very sharply serrate, the teeth at the angle longer ; 4 

 spiuules on the humeral plate ; subopercular flap ending 6 scales before 

 dorsal fin. Maxillary nearly reaching front of pupil, 2i in head. Dorsal 

 spines strong, the second a little shorter than third, the third 1| in head; 

 second anal spine very long and straight, \\ to \k in head (in Pacific Coast 

 specimens, var. medium, Giinther, this spine is somewhat curved, a little 

 shorter so far as known, than in Atlantic specimens, var. 2>i'dimacula,li to I5 

 in head) ; caudal fin deeply forked, the lobes pointed, li in head; ventral I3 

 in head, reaching more than halfway to anal ; pectoral shortish, 2^ in head. 

 Air bladder simple. Lateral line black. Dark olive, the sides bright silvery; 

 ventral pale yellow, tipped with black ; some yellow on anal, with black 

 behind the spines ; upper fins dusky ; pectoral colorless, a little dusky at 

 its base. Length 15 inches. Both coasts of tropical America ; very com- 

 mon in Cuba, Jamaica, and south to Brazil, and also on the west coast 

 from Mazatlan to Panama ; a food-fish of some importance. Except that 

 the second anal spine is a little shorter and more curved in Pacific 

 examples {Ceutropomus medius, Giinther), we find no difference between 

 these and the typical pedimacula. On both coasts the species enters the 

 rivers. Here described from specimens from Havana and Mazatlan. (pes, 

 foot; macula, spot.)

Head 2§; depth 3f to 3f. D. VII-I, 10; A. Ill, 7; scales 8-52 to 54-13, 

 23 to 26 before dorsal. Body moderately elongate, somewhat compressed, 

 but not flat-sided, the back elevated, the belly straight ; nape convex ; 

 snout projecting, the profile behind it concave; maxillary 2| in head, 

 reaching front of pupil ; snout 3^ to 3i * in head. Lower jaw strongly 

 projecting; eye 5J^ in head; preorbital with rathar small retrorse serrse 

 posteriorly ; preopercle with sharp, distinct teeth on posterior limb, 2 to 

 4 enlarged teeth at the angle ; moderate teeth below ; suprascapula with 

 5spines; opercular flapending about 6 scales before dorsal, the scales before 

 dorsal being much reduced in size. Scales of body large. Dorsal spine 

 strong, the third much longest and strongest, 1| in head, fourth slenderer 

 and shorter ; second anal spine very strong, straight. If in head, shorter 

 than the very slender third spine ; caudal well forked, li to IJ in head ; pec- 

 toral 11; ventral If. Color pale greenish, silvery below, the lateral line 

 black and conspicuous, becoming straight under last dorsal spine ; upper 

 fins slightly dusky ; ventrals pale or with a few dusky specks near tip ; 

 a little dusky behind second anal spine. Pacific Coast of Mexico Here 

 described from two specimens, 1534 (L. S. Jr. Univ. Mus.), 15 inches long, 

 and 201 (L. S. Jr. Univ. Mus.) 14 inches long, both taken by Dr. Gilbert
