D. vi/11 ; A. 9; P. 16; V. i/5 ; C. 16. About 37 scales between 

 the axil and the hypural joint, and 17 between the anterior dorsal and 

 anal rfiyn. 



Depth 57 in the lenp^th to the hypural joint; head 8'9 in the same. 

 Eye slightly shorter than the snout, whicii is 35 in the head. Interorbital 

 space about 4 in the eye. Breadth between the pectoral bases equal to 

 the depth. Depth of the caudal peduncle 2, pectoral 1 in the head. 



Head largely naked, with a few scales on the upper portion of the 

 operculum, and one or two very indistinct ones between the mucigerous 

 ridges on the cheeks. All surfaces of the head bear raised lines of papillae 

 which are regular!}^ airanged and disposed as shown in the accoinpanying 

 illustration; in addition, series of small pores extend around the e3'e and 

 preopercular margin. Eyes close together, superolateral, separated by a 

 narrow bony interorbital area. Snout obtuse and rounded. Nostrils 

 tubular. Mouth vei'y oblique, the maxilla not reaching the vertical of 

 the anterior margin of the eye. Mandible projecting beyond the upper 

 jaw ; its lower surface with numeious mucigerous ridges. A band of 

 small pointed teeth in each jaw, which is three or four rows wide anteriorly, 

 and becomes gradually nan-ower laterally ; the outer teeth are slightly 

 laiger than the others. Palate toothless. Tongue rounded, slightly 

 notched in the middle line, and largely free. The s[)ace between the gill- 

 openings is twice as wide as the eye; exposed edge of the shoulder girdle 

 smooth and shai-p. 



Body subcyiindi'ical anterioil}-, compressed posteriorly. It is covered 

 with moderately large cycloid scales, which increase in size backwaids, a 

 row along the median line of the caudal half being slight)}' largei' than 

 the others ; the scales extend forward on the nape to just behind the eyes, 

 and cover the breast and base of the pectoral fin. Vertical series of muci- 

 gerous papillae extend backward from behind the pectoral to the caudal 

 base, between which some horizontal lows are interspersed. Genital 

 papilla well developed. 



First dorsal low and rounded, the fifth spine subequal to the i)OBt- 

 orbital portion of the head. Dorsal rays increasing in height to the 

 penultimate, which reaches backward to the upper caudal rays. Anal of 

 similar form to the second dorsal, but shorter and slightly lower. Pectoral 

 large and rounded, not quite reaching the vertical of the vent. Ventrals 

 inserted before the pectoral, completely united, and reaching about two- 

 thirds of theii- distance from the vent. Caudal elongate, obtusely pointed. 



Colour. — Brown, each scale with a darker border, and a lighter 

 median band along the middle of the sides posteriorly. Some indefinite 

 broad, darker cross-bands are present on the back and sides ; one descends 

 from the base of the spinous dorsal, a second narrower one from the 

 anterior dorsal rays, and a third broad one from the hindei- portion of the 

 soft dorsal ; two others are present in front of the dorsal fin. The vertical
