REPORT ON THE SHORE FISHES. 29 



Lophonectes yallus, n. sp. (PI. XV. fig. B). 



D. 87, A. 71, L. lat. 68. The height of the body is two-fifths of the total leugth 

 (without caudal), the length of the head two-ninths ; the snout is short, shorter than the 

 eye, the diameter of which is a little less than one-fourth of the length of the head. Eyes 

 separated by a very narrow ridge, the lower somewhat in advance of the upper, the 

 upper not encroaching upon the upper profile. The mouth is oljlicpoly directed upwards ; 

 the maxillary extending to the front margin of the eye and etpalling it in length. 

 Adult males with pointed tubercles on the snout ; two on the sides, and one at the 

 mandibular symphysis. The dorsal fin commences opposite the anterior nostril, and is 

 continued to nearly the root of the caudal. In the adult the five anterior rays are pro- 

 longed into more or less long filaments. Left pectoral longer than the right, or as long 

 as the head without snout. Ventrals separate : the rays of the left are arranged in the 

 same line as the anal, the rio-lit ventral beino; shorter. The curve of the lateral line is 

 sub-semicircular and short. Brownish, marbled with darker. Vertical fins irregularly 

 and finely dotted with black. Ventrals with a black spot. Length of specimens, 2^ to 5^ 

 inches. Station 162; 38 fathoms. Ofli' Port Jackson ; 30 fathoms. 



LcBops, n. gen. 



Body oblong ; head small ; cleft of the mouth very narrow, with the dentition much 

 more developed on the blind side than on the coloured. Teeth vilHform, in narrow bands ; 

 palatine and vomerine teeth none. Dorsal fin commencing above the front margin of the 

 eye. Scales small, thin, deciduous. Eyes on the left side. This genus appears to rejjre- 

 sent Pleuronectcs in the Southern Hemisphere. Arafura Sea. South-Eastern Australia. 



LcBops parviceps, n. sp. (PI. XV. fig. A). 



D. 104, A. 86. The height of the body is contained twice and two-thirds in the total 

 length (without caudal), the length of the head five times and one-third. The snout is 

 very short. The eye rather large ; its diameter being contained thrice and one-third in 

 the length of the head. A very narrow ridge, longitudinally grooved, sej^arates the two 

 eyes, the lower being conspicuously in advance of the upper. The mouth is directed 

 upwards, and the maxillary of the left side extends scarcely to below the anterior margin 

 of the eye. The dorsal fin commences opposite to the front margin of the ujaper eye and 

 is continued to the root of the caudal, the rays being of moderate length.- Caudal 

 rounded. The left pectoral rather longer than the right and as long as the postorbital 

 portion of the head. The rays of the left ventral are arranged in the same line as the 

 anal, the right ventral being entirely on the right side. The lateral line makes a very 

 short semicircular curve anteriorly, and is straight for the remainder of its course. The 

 colour appears to have been uniform bro^ai. Arafura Sea. South-Eastern Australia.
