DESCRIPTION OF TWO NEW SPECIES OF FISHES (APRION ARIOM- 
. MUS AND OPHIDIUM BEAN!) FROM PENSACOLA, FLORIDA. 
By DAVID S. JORDAN and CHARLES H. GILBERT. 
1. Aprion ariommus sp. nov. 
Head 34 in length to base of caudal; depth, 32. D. XI, 11; A. III, 8. 
Lateral line with about 60 tubes, the number of transverse series of 
scales being about 70; about 7 scales between first dorsal spine and 
lateral line. 
Body elliptical, rather elongate, moderately compressed, highest near 
the front of the dorsal, the anterior profile regularly and not rapidly 
declined. Snout short, 44 in head, the premaxillaries in front being 
about on the level of the middle of the eye. Mouth oblique, the lower 
jaw slightly projecting; maxillary reaching about to front of pupil, 
24 in head; maxillary naked, striate, without supplemental bone, slip- 
ping under the edge of the narrow, entire preorbital. 
Jaws each with a moderate band of villiform teeth, those of the outer 
series enlarged, especially above, none of the teeth distinctly canine 
like. Vomer, palatines, and tongue with bands of villiform teeth, those 
on the vomer in a long, somewhat arrow-shaped patch, being prolonged 
far backward on the median line, as in many species of Lutjanus ; teeth 
on the tongue in two patches, a small one before a large one. Lower 
jaw thin, without evident pores. 
Hye very large, 24 in head. Interorbital space flattish, 12 in eye. 
Occipital crest rather low, thin, and sharp. Preopercle sharply toothed, 
the teeth near the angle sharp and straight, directed backward, the 
teeth on posterior limb directed upward. No notch above angle of pre- 
opercle. Opercle ending in two flat points, between which is an emar- 
gination. Suprascapula strongly serrate. 
Gill-rakers long and strong. Pseudobranchie large. 
Seales small, ctenoid, those above lateral line in very oblique series, 
not at all parallel with the lateral line, those below the lateral line form- 
ing curved series, which are convex downwards. Bases of soft dorsal 
and anal naked. Pectoral without axillary scale. 
Dorsal moderately but not deeply notched; the spines rather strong, 
not very unequal, the longest (fourth) about 24 in head. Caudal long, 
rather deeply forked, its lobes about 14in head. Anal spines short, the 
second longest 34in head. Pectorals long, 12 in head. entrals, 14. 
Color in spirits silvery white, perhaps rosy in life. Sides with faint, 
dark olive, narrow, undulating streaks which follow the direction of the 
rows of scales. Fins plain, probably red in life. 
Two specimens of this species, each about six inches long, were ob- 
tained by Mr. Silas Stearns from the stomachs of red snappers (Lutjanus 
blackfordi Goode & Bean) on the “Snapper Banks” off Pensacola. Both
