Body and head forming a subspherical mass, short, broad, rounded on the 

 top, the sides, and the front, somewhat flattened on the lower surface at the 

 disk ; caudal section from the vent backward narrow and slender. From 

 the snout to the anal fin is hardly more than one fourth of the total length ; 

 the length of the body without tail or head is little if any more tlian half of 

 the head's length. Head short, less than one fifth of the total, very convex 

 on the crown, on the snout and on the cheeks, flattened at the throat, as 

 wide as deep, high at the occiput, curving downward steeply on the fore- 

 head. Snout short, as long as the eye, deep and wide, very convex across 

 the top, broadly rounded from side to side, produced very little forward of 

 the mouth. Mouth large, horizontally cleft; lower jaw little shorter, in- 

 cluded ; maxillai-y reaching a vertical from the front edge of the eye. Eye 

 medium, about as long as the snout, length nearly two fifths of the width 

 of the interorbital space, size not far from that of the ventral disk. Teeth 

 small, slender, subconical, acuminate, in villiform bands. Disk a trifle longer 

 than wide, length equal to half the distance from the end of the snout, its 

 distance from the vent hardly ecjual to its diameter. Gill openings narrow, 

 as wide as the eye, above the base of the pectoral. Operculum small, hind 

 angle a short spine, almost horizontal, slightly bent upward. Epicoracoid 

 spine-like, strong, two thirds as long as the head, reaching far down on the 

 flank, that is, below the level of the upper part of the pectoral, bent forward 

 in the middle. 



Vertical fins confluent, well developed ; dorsal originating but little back- 

 ward of the vent, above the axil of the pectoral, rising gradually toward the 

 caudal ; anal origin seven or eight rays farther from the head ; both fins 

 overlapping the caudal more than half of its length and connected with it
