from its centre. Snout obtusely conical, its upper profile 

 very oblique and broadly rounded when viewed from 

 above. Upper lip projecting well beyond the preorbital 

 bones when the mouth is closed and well beyond the lower 

 jaw. Maxillary reaching backward beyond the vertical 

 of the anterior margin of the eye. Interorbital space 

 very narrow, forming a shallow groove. Eyes very large 

 and rising high above the profile of the head. Preoper- 

 cular spine curved upwards at its distal extremity to 

 form a spine of the same size as two others on its upper 

 margin; no antrorse spine at the base below. Gill- 

 openings exposed on the supero-lateral surface of the 

 neck, and separated by a space which is much less than 

 that between the outer margins of the eyes; they are 

 much nearer the bases of the pectorals than the eyes, 

 and well above the level of the former. A broad band 

 of teeth in each jaw which is widest anteriorly and 

 extends farther back in the lower than in the upper; 

 palate with large fleshy papillae, but toothless. 



Body not depressed, the caudal peduncle little 

 broader than deep at the middle of its length. Lateral 

 line crossing behind the occiput and curving downward 

 in advance of the pectorals; it is then arched upward 

 above that fin and descends again to the middle of the 

 side behind its tip; the usual cephalic extensions are 

 present, one descending towards the preopercular spine 

 and another to the hinder angle of the eye, but it 

 apparently does not cross the cheek. A small, well 

 developed anal papilla. 



First dorsal spine inserted above the preopercular 

 spine and a little behind the vertical of the origin of the 

 ventrals; all four spines are produced into extremely 

 slender filaments and are longer than the base of the 

 second dorsal; the second is incomplete and the third 

 extends beyond the base of the last dorsal ray. Second 

 dorsal elevated, its median rays longest, but not reaching 

 backward to the hypural joint when adpressed; all are 

 bifurcate and the last is again divided to its base. Anal 

 rays simple, only the last divided to its base; they are 

 lower than those of the dorsal and increase in length 

 backwards. Pectorals rounded, all but the upper ray 

 bifurcate, the median reaching backward to beyond the 

 vertical of the second anal ray; the entire base of the 

 pectoral fin is exposed. Ventral rays branched, the
