D. vi/9 ; A. 8 ; P. 16 ; V. i/5 ; C. 15. 37 rows of scales between 

 the axil and the hypural joint, and 14 between the anterior dorsal and 

 anal rays. 



Depth before the ventrals about 5 in the length from the premaxillary 

 symphysis to the hypural joint ; head without the mandible, 4 in tha 

 sq^me. Eye 5'2 in the head, and 1-8 in the interorbital space ; it is a little 

 shorter than the snout. Breadth before the pectoral bases I'l in the 

 depth; depth of the caudal peduncle 1"3 in its length. 



Head broader than deep, flat above, and almost entirely covered with 

 scales of moderate size ; they extend forward to before the posterior, nostrils 

 on the upper sui'face, and some on the nape are a little larger than the 

 body-scales ; some of the scales on the upper surface of the head and cheek 

 are cycloid, but the remainder are ctenoid ; there are about twenty-one 

 befoi'e the doi'sal fin. No distinct mucigerous system above the eye, and 

 no supi'aciliary scales. Several rows of microscopic mucigerous papillae 

 extend downward from the eye, and two others cross the cheek horizon- 

 tally, while further series are present above and behind the preopercular 

 margin, and beneath the mandible. Preopercular margin free and exposed ; 

 several large open pores are present around its border, along the parietal 

 groove, and above the nostrils. Eye of modei^ate size, superolateral, but 

 not cutting the upper profile ; it is situated within the anterior half of the 

 head. Interorbital space very broad and flat. Snout broadly rounded, 

 its upper profile scarcely interrupted by a knob formed by the posterior 

 processes of the premaxillaries ; mandible projecting, the symphj'sis 

 rounded. Mouth oblique, the maxilla i caching to below the middle of 

 the eye. Nostrils separated, the anterior tubular and overhanging the 

 lip, the posterior with dermal margins and near the eye. Each jaw with 

 a band of villiform teeth, and an outer row of larger conical ones ; in the 

 mandible the outer row is wanting laterally, and is replaced with a row of 

 enlarged inner teeth. Tongue broad, subtruncate and free anteriorly. 

 Gill-openings extending forward to below the hinder margin of the eye.
