560 



Head 3 in body length; depth, 2\ to 2J; eye, 3 to 3J; snout, 2|; 

 maxillary, 3; suborbital width, 3^; D. X., 10; A. Ill, 10; scales in 

 longitudinal series 50 to 52, in transverse series from dorsal to anal 

 insertion 5^/16 or 17. 



Body deep, compressed, its width about 3 in depth. Dorsal and 

 ventral profiles similar, save for low position of tip of snout below 

 axis of body. Head deeper than long, its dorsal outline arched and 

 rising rapidly. Prefrontals prominent, interorbital space narrowest 

 above- pupils. Preorbitals deep as long, nearly quadrate, sheathing 

 maxillary almost entirely. Jaws equal; mouth small; maxillary 

 ending below anterior margin of eyes; lips papillate. Preopercular 

 angle smooth, its posterior margin slightly oblique. Opercle short 

 with two flat, obtuse points, the upper little prominent. In upper

riorly, in an outer row with a band of small, slender, sharp teeth 

 behind them, latter merging into a single lateral row, posteriorly, of 

 stout conical teeth, nearly molar in character and of slightly shorter 

 length than canines. Lower jaw similarly toothed. Vomer, pala- 

 tines and tongue edentulous. 



Dorsal spines not flexible, fourth but very slightly longer than 

 remainder, 2\ to 3 in head. Dorsal rays higher, fifth and longest con- 

 tained 2 in head. Anal spines strong, third longest, 2J tP 3 in head; 

 first two-fifths of length of third. First anal rays longest, slightly shorter 

 than dorsal. Pectoral 1 \ in head, its first ray longest, its last two-fifths 

 of its length. Ventrals extending to third anal spine, its first ray 

 slightly filamentous, \\ in head. Caudal forked, its lobes (measuring 

 from hypural plate) twice length of middle rays, which are \\ times 

 longitudinal diameter of eye.
