1714. ISACIELLA BREVIPINXIS ( Stein dachner). 



Head 3fr ; depth 3. D. XIII, 16 ; A. Ill, 12 or 13 ; scales 10-65-20 ; maxillary 

 3 in head; eye 4; preorbital 6 ; pectoral 1; snout 3f: spinous dorsal 

 2 ; second anal spine 5 ; longest anal ray 3| ; base of soft dorsal in base of 

 spinous dorsal 1. Preopercle weakly serrate; preorbital very narrow, 6 

 in head ; mouth small, maxillary longer than snout. Body rather fusiform 

 somewhat compressed, the back elevated, anterior profile steep, convex; 

 mouth with narrow bauds of brush -like teeth, the outer above slender 

 close sot and a little enlarged; maxillary reaching to anterior edge of eye; 

 gill rakers short and slender, x-\- 16; snout short, blunt; eye large; lower 

 jaw included. Scales small, extending from preorbital to fork of caudal, 

 covering bases of pectorals, veutrals, soft dorsal, and anal; base of each 

 scale at base of trunk and posterior part of head covered with minute 

 accessory scales ; a series of small scales on the membrane behind each 

 ray; dorsal and anal fins in a low scaly sheath; dorsal fin slightly 

 notched, last spine 1| in first soft ray; spinous dorsal low, spines slender; 

 soft dorsal and anal very low, third anal spine longest; pectoral sharp, 

 falcate, as long as head; caudal long, deeply forked. Color light bluish- 

 gray, with brownish-gray stripes following the rows of scales. Pacific 

 coast of Mexico ; rather rare. This species and the preceding form a transi- 

 tion from Microlepidotus to typical Orlhopristis. (ftrerw, short; pinna, fin, 

 from the low dorsal and anal.)

548. MICROLEPIDOTUS, Gill. 

 Microlepidotus, (JiLL, Proc. Ac. Nat. Sci. Phila. 1862, 256 (inornatus). 



This genus is near Orikopristit, differing chiefly in the elongate form, 

 very small scales, increased number (14) of dorsal spines, and deeply 

 notched fins, the dorsal and anal being scaleless. The skull is very broad 

 and rounded, the interorbital width greater than length of snout; the 

 temporal crest rises above the pupil and is high, more than half the 

 height of the supraoccipital crest, which rises above front of pupil. One 

 species known. (//zKpo, small; XsTtldooro^j scaled).

 second anal spine 6; longest anal ray 3|; base soft dorsal in spinous 1|. 

 Body elliptical elongate, slightly compressed, the back moderately elevated, 

 profile convex from nape to snout; mouth large, with numerous bristly 

 teeth, curved inward, larger in front ; maxillary reaching to anterior edge 

 of eye; interorbital space very broad ; preorbital very narrow ; jaws sube- 

 qual ; preopercle sharply serrate ; gill rakers short, 8 + 17 ; snout bluutish, 

 equal to maxillary ; eye very large. Scales very small, extending from
