First dorsal ii, 10; ventral II; pectoral 20 or 21 ; 14 seales in a series do-nnward and liackward 

 from origin of first dorsal to lateral line, 11 between lateral line and origin of seeonil dorsal (S in .1/. 

 }iolocentri(x). 



Head short and liigh, <'oini)ressed, the greatest dejitli eontained 1.2 times in its length; upper pro- 

 file nearly straight from dorsal fin to snout, a very sliglil depression above orbits; profile of snout gently 

 deeurved to rostral tubercle, descending thence in a vertical line to front of ])remaxillaries; head firm, 

 without conspicuous mucous cavities, the scales everywhere firndy adherent; snout terminating antero- 

 superiorly in a tubercle covered with spines radiating in all directions from the center; a pair of smaller 

 spinous tubercles are separated from the first by less than half its <liameter; suborbital fiat, without 

 ridge; interorliital space narrow, very slightly concave, its width slightlj' less than length of snout, O.S 

 diameter of orbit; upper rim of orbit encroaching on upper ]irofile; snout 0.25 length of head; eye 

 circular, 3.:-! in head; distance from rostral tubercle lo i)rcmaxillaries 0.2 length of head; front of 

 premaxillaries far in advance of nostrils; maxillary scarci'ly reaching vertical from front of pujiil, 

 contained 3.25 in length of head, and equal to width of mouth; teeth in very wide villiform bands in 

 both jaws, the outer series in the upper jaw scarcely enlarged; length of l:)arbel 0.7 diameter of orliit; 

 least width of the suborbital 0.3 diameter of orliit; preopercular angle not produced, the posterior 

 margin nearly vertical, convex in its njiper luilf, concave immediately above the angle.

First dorsal fin very long; s(!con<l ilorsal si)ini! large, provided with 17 rather fine .serrations 

 evenly distributed for its entire length, its flexible portion short, its tip scarcely projecting beyond that 

 of tlie first succeeding ray; total length of spine equaling distance fi-ou\ tip of snout to base of upper 

 pectoral ray; rays of second dorsal very short and inconspicuous, the base of tlie first ray reached by 

 the seventh ray of first dorsal; interspace between dorsals e(iual to base of anterior fin; first anal ray 

 under middle of anterior dorsal, its distance from base of iimer ventral ray one-half distance from 

 latter to edge of gill-membrane; inner ventral ray rea<'liing anal origin, the other rays extending well 

 beyond it, the filamentous outer ray reaching base of fifteenth anal ray, it.s length 1.1 in that of head; 

 pectoral wide, extending to ojiposite eleventh anal ray, its length T.45 in head; a small naked jlit on 

 middle line of breast between the outer ventral ravs.
