in head. Mandibular teeth in a villiform band which is of moderate width 

 anteriorly and tapers rapidly on sides ; an outer series of distantly placed 

 moderate canines; teeth in preinaxillaries similar to those below, the 

 canines small, a pair on each side enlarged, but small for this genus ; vomer- 

 ine teeth in a diamond-shaped patch, the sides subequal, concave; pre- 

 ocular margin with a rather deep emargination above the angle ; above the 

 emargination the edge is very minutely and finely serrulate, at the angle 

 provided with a few short slender rather distant spines. Gill rakers strong, 

 those above angle all short, the one at angle abruptly lengthened, about 

 half diameter of eye; seven developed on horizontal limb of arch. Pos- 

 terior nostril elliptical. Five or six series of scales on cheeks, the band 

 running upward to level of upper margin of orbit; a single narrow band 

 of scales on occiput, separated by a naked space from those on nape; top 

 of head, snout, mandible, preopercle, maxillary, and anterior half of inter- 

 opercle naked; scales above lateral line in series parallel with the lateral 

 line ; scales on the breast not much reduced, as large as those on opercle ; 

 basal portions of dorsal and anal densely scaled, the scales forming a sheath 

 at base; basal f of caudal densely scaled. Dorsal spines heavy, not flex- 

 ible, the longest 2 in head ; second and third anal spines about equal, half 

 the length of snout and eye ; soft dorsal and anal low, rounded, the longest 

 ray (measured from free edge of sheath) about head ; caudal lunate, the 

 middle rays the outer, If in head; pectorals very long, nearly reaching 

 vertical from vent, 1J in head; ventrals If in head. Color, back and top 

 of head deep olive; lower half of sides and below dark reddish-purple; 

 many of the scales on sides with a silvery spot near the margin, producing 

 faint lengthwise stripes; fins reddish-purple, the basal portion of soft 

 dorsal and caudal tinged with olive; iris silvery, with inner and outer 

 orange circle; no blue lines on the head; inner lining of gill membranes 

 and the shoulder girdle largely orange-red ; pectoral fins orange-brown. Of 

 rare occurrence at Panama, but occasionally taken in considerable num- 

 bers. It is a small species, reaching a length of about 17 inches. A strongly 

 marked species, quite unlike any other. (Named for David Starr Jordan.)

(PARGO PRIETO; PARGO MARESfO ; PARGO NEGRO.) 



Head 2f ; depth 3 ; eye 5f to 4f in head. D. X, 14 ; A. Ill, 8, rarely III, 7 ; 

 maxillary 2f-; preorbital 51; scales 6-48-13. Body comparatively elon- 

 gate, the back little elevated ; profile very gently curved ; snout long and 

 pointed, i length of head; eye small, less than breadth of the wide pre- 

 orbital ; maxillary barely reaching to opposite front of orbit, its length 

 2f in head; each jaw with a very narrow band of villiform teeth, outside 

 of which is a single series of larger teeth, those in sides of upper jaw 

 small, 2 in front, however, developed as large fanglike canines, larger 

 than usual in this genus, their length about equal to the diameter of the 

 pupil ; a pair of smaller canines near the middle of the upper jaw, between 

 the large ones; conical teeth of lower jaw distant, caninelike, 6 to 8 in
