POECILOPSETTA, Gthl\ 



17. Poecilopsetta maculosa, n. sp., PI. VII., fig. 1. 



D. 56. A. 46. V. 5. C. 18. 



Height of the "body about If in the total, without candal ; lengtli 

 of the head a little more than 3|. The length of the snout is abont 

 half the major diameter of the lower eye, which latter is neai-ly one- 

 third the length of the head — the upper eye being markedly larger. 

 The eyes are on the right side, the lower hardly in advance, the upper 

 strongly encroaching on the dorsal profile : they are separated by a 

 fiat scaly space, the breadth of which is nearly equal to the length of 

 the snout. The mouth-cleft is oblique and narrow, the maxilla being 

 hardly more than one-fourth the length of the head : the jaws ai-e 

 equal in front and equally developed on both sides, as are the teeth, 

 which are villiform and in a crowded row in both jaws. The gill- 

 membranes are broadly united below the throat. 



The head, body, and caudal fin are covered with minute thin cycloid 

 scales : the lateral line has a wide curve above the pectoral fin. The 

 dorsal fin begins above the middle of the eye and extends to the base 

 of the caudal peduncle : its rays, like those of the anal fin, are simple, 

 the longest being less than one-fourth the greatest body height. The 

 caudal fin is large and hastate, its len^h being nearly one-fourth the 

 total. The right (coloured) pectoral is rather more developed than 

 the left, but is not longer than the eye. The ventrals are quite equal, 

 opposite, and symmetrical, and are about as long as the eye. 



Colours : right side silvery -grey with numerous large, well-defined, 

 more or less oval blotches, varying from dusky grey to jet-black — the 

 black blotches, in regular alternation with lighter ones, forming a 

 rino- round the circumference of the body ; pectoral with a black blotch, 

 caudal with two — one above, the other below : left side with several 

 longitudinal series of black blotches along the middle of the body, and 

 with a series round the circumference of the body, corresponding blotch 

 for blotch with those on the coloui'ed side. 



Length nearly 3'75 inches. 



Loc. Bay of Bengal, Station 162 ; 145-250 fms.

 Closely resembling P. maculosa, but \'Bry easily distinguished by 

 the following differences : — The height of the body is only about one-
