PLEURONECTES.] PISCES (OSSEI) MALACOPT. 465 



in advance ; between them an osseous ridge, passing upwards behind to 

 unite with the lateral line : gill-opening large ; opercle small, of a tri- 

 angular form ; subopercle and interopercle much developed : lateral line 

 very much arched above the pectoral, afterwards straight, and carried on 

 to quite the end of the caudal : scales large ; those on the eye-side of the 

 body with their free edges finely ciliated, communicating a roughness to 

 the touch ; those on the opposite side smooth, with their margins entire ; 

 scales on the lateral line with a slightly elevated oblong tubercle : dorsal 

 commencing about half-way between the extremity of the snout and the 

 upper eye, and carried on very nearly to the caudal ; greatest elevation 

 of the fin a little beyond the middle, where it equals one-third of the 

 depth of the body; most of the rays simple, some of the longest only 

 divided at their tips ; the first four or five nearly free, the connect- 

 ing membrane being very low : anal commencing in a line with the pos- 

 terior lobe of the opercle, and answering to the dorsal ; before it a blunt 

 point : caudal oblong, rounded at the extremity, its length rather more 

 than half the depth of the body ; all the principal rays, except the two 

 outermost, branched : pectorals inserted a little below the middle of the 

 depth, and in a line with the commencement of the anal ; very unequal ; 

 that on the eye-side rather more than half the length of the head ; the 

 opposite one more than one-third shorter ; first ray very short ; third and 

 fourth rays longest : ventrals entirely in advance of the pectorals, and 

 appearing like a portion of the anal, only double, from which they are 

 separated by the vent:

{Colours.) Upper side light reddish brown, here and there mottled and 

 spotted with dusky and darker brown: under side white. 



First observed by Mr. Jago on the coast of Cornwall, where it has 

 been since represented, by Mr. Hanmer and Mr. Couch, as very common. 

 Occasionally met with on other parts of the southern^ as well as on the 

 western, coast. The specimen from which the above description was 

 taken occurred at Hastings. In Cornwall called a Lantern-Fish.

LENGTH. Five to six inches. 



DESCRIPT. (Form.) Oblong-oval; the body narrowing behind more 

 gradually than in the last species, and not so suddenly contracted before 

 the caud'al; thin and somewhat pellucid: greatest breadth, dorsal and 

 anal fins excluded, one-third of the entire length : head one-fourth of the 

 same, excluding caudal : profile slightly .emarginated before the eyes : 

 gape moderate; jaws nearly equal; lower one obliquely ascending; both 

 with fine velvet-like teeth : eyes placed as in the Whiff, but not so large 

 in proportion : lateral line arched above the pectoral, afterwards straight : 

 scales large, thin, very deciduous; their free edges finely ciliated, and 

 emarginated ; those on the lateral line with an oblong tubercle as in the
