Bodv moderately elongate, compressed behind. Head low, the 

 width slightly less than the length, the difference about equal to 

 length of orbit. Eyes small, a little less than snout and 1.7 in inter- 

 orbital space, 8| in head. Interorbital width 5 in head. Opercular 



spine 3] to 5 in head. Mouth nearly verti- 



Aeal, the lower jaw very prominent. Maxil- 

 lary 2\ in head, reaching behind eye. Man- 

 dible 1 -j in head. Teeth rather short, conic 

 incisors, oval in front view, with a longcut-

and near the front of the premaxillary the teeth are crowded so as to 

 appear in two very irregular rows or a narrow cardiform band. There 

 are no teeth on t lie shaft of the vomer, the single row of teeth on that 

 bone being a direct continuation of the row on the palatines. There is 

 no indication of a tendency to form canines in fish of any size. Pec- 

 toral litis obliquely rounded, 1$ in head, reaching to about sixth or 

 seventh anal ray (eighth in the smallest specimen). Caudal rounded 

 except in the smallest specimen, where it has the upper and lower rays 

 (one upper and one lower ray) much produced, the middle rays 1| 

 in length of outer ones. The (in membrane behind the last dorsal and 

 anal rays just reaches to the base of the caudal rays. 



Color in alcohol dark gray with a conspicuous reticulation of 

 grayish white lines above, grayish white below. The spinous dorsal 

 i- black. All the other fins are colored like the back and edged with 

 white. Whole mandibular region colored like the back, but with 

 liner reticulations.
