PISCES ABDOMINALES. ESOX. 
The fins. The dorsal and anal fins as in the last species, but the ventral situated nearer the tail. The 
pectoral high, straight, acuminate above. The caudal fin differs from the last, being bilobed, or divided 
unequally: the lower lobe much the longest. 
The colour. The crown and back changeable ; the opercula, sides, and abdomen, silvery; the ventral and 
anal fins glassy-white; the others bluish, paler than the back. 
Length of the subject described, from the upper jaw to the caudal fin, nine inches four lines. 
No. CLXXVIII. 
Esox maxilla superiore brevi; inferiore longissima, subulata; corpore lineare; squamis variis; 
cauda biloba. 
The Esox with a short upper jaw ; the under, awl-form and extremely long; the body 
linear, covered with scales of diverse shapes ; the tail unequally bifid.

This species, in the structure of the mouth and lower jaw, agrees with the last, but in the shape of the trunk, 
approaches nearer No. CLXXVI.; it differs however from all I have hitherto found described. 
The body linear, compressed, squamous; scales imbricate, loose, but singularly varying in shape; some 
almost square, others oval or angular. 
The head depressed, compressed, smooth, without scales, except on the crown ; the front deeply grooved in 
the middle. The mouth as in the last species ; the upper jaw short, the denticulate part of the under cor¬ 
responding; but then it projects into a taper, sharp-pointed, bony, awl-shape process, three inches three lines 
in length. Teeth numerous, linear. Tongue roundish, small, cartilaginous, smooth, bridled ; the palate rough. 
The eyes supreme, round, larger than in the last. The nostrils double, in a pit near the orbit. The opercula 
also, as in the last, without scales. 
The trunk. The back straight, roundish, carinate; the sides compressed, the breast and abdomen attenuate, 
carinate, and straight to the anal fin, where the tail becomes narrower by the lower part slanting towards the 
caudal fin, for the upper edge hardly declines. The lateral line high, straight, parallel to the back. The lower 
line near the belly, found in the three preceding species, is here wanting; but the anus, as in the others, 
remote. 
The fins. The dorsal and anal are situated as in No. CLXXVI.; the pectoral middle, remarkably long, 
acuminate above, point setacious; the ventral remote, extremely small; the caudal bilobate as in the last species. 
the upper lobe very short. 
The colour. The upper part of the head and back a dark blue, brightening on the sides to a bright leaden. 
The colour of the fins was accidentally omitted.
