PHILIPPIC MACROUROID FISHES — GILBERT AND HUBBS. 517 



of first dorsal is not oblique. Greatest depth of body, below origin 

 of first dorsal, 2.33 in length of head ; greatest width, across' pectoral 

 bases, 3.0; the depth, at a distance behind snout twice the length of 

 head, is contained only twice in the postorbital length, and is about 3 

 times the width of the tail at the same point. The sides of the head 

 are convex; the snout is heavy and broad; its preocular length is 

 contained 2.15 times in length of head; it preoral length, 2.3 times; 

 its width at base, 2.65 times ; the width of the snout at anterolateral 

 angles is a little less than the length anterior to that point. The in- 

 fraorbital, occipital, supranarial, supraorbital, and postorbital ridges 

 are exceedingly strong and heavily spined. The preopercular ridge 

 and margin are oblique ; the sharply pointed flap of the subopercle, 

 concealed by the produced lobe at the angle of the preopercle, is

directed downward and backward, and is almost as long as the pupil. 

 The orbit is oval and small ; its length is equal to the least interorbital 

 width, and is twice the least distance between the occipital ridges; 

 orbit 4.3 in head, 2.0 in snout, 1.3 in postorbital. Least suborbital 

 width, 2.4 in postorbital. The upper jaw extends from below the 

 posterior nostril backward to below the hind margin of the pupil; 

 its length is contained 4.65 times in the head. The barbel is slender 

 and very short, being contained 7.5 times into the postorbital. The 

 teeth are in rather narrow bands in the jaws; there are only about 

 three teeth in a cross section of the mandibular band laterally. Six 

 branchiostegals. 



Distance between isthmus and base of ventral, 1.4 in distance from 

 base of ventral to center of anus, 1.5 in postorbital length. There are 

 no naked areas on the breast. 



The scales are large, being in 4^ rows from the origin of the second 

 dorsal to but excluding the lateral line series ; this number does not
