1889.] Species of Fishes from the Bay of Bengal. 301 



lobe with a similar pore. The interorbital space is nearly flat from side 

 to side, and as broad as the eye is long. Nostrils large. Mouth oblique ; 

 the maxilla reaches the vertical from the posterior border of the orbit. 

 Lips thick, and beset with filiform papillae, the upper lip most thickly 

 so. Villiform teeth in both jaws : in the premaxillie an outer row of 

 sharp curved teeth of which the anterior four are canine-like ; in the 

 mandibles an inner row of distant sharp conical teeth. Preopercular 

 margin finely serrated, with some small spiny teeth at its angle : two 

 weak opercular points. Gill-rakers on the inner edge of first arch 

 bacillate ; on the other arches in the form of sharply- toothed double- 

 crowned tubercles. Scales ctenoid, except on snout and infra-orbital. 

 I All the dorsal spines weak and flexible ; the 1st very small, the 3rd and 



4th the highest and equal to nearly half the body height, lat anal spine 

 almost invisible ; the 2ud a little longer than the eye, and not half the 

 length of the rays. Pectorals large and falciform, in length equal to the 

 head without the snout, or to the body height. Ventrals two-thirds the 

 length of the pectorals. Caudal a sharp-pointed wedge ; its length 5^ 

 to 5;f in the total. Colours in life : back silvery shot with metallic 

 green and red ; belly like burnished silver : a blue blotch on opeixulum . 

 pectorals yellow, the other fins grey suffused with orange. The stomach 

 with its csecum occupies nearly the whole length of the abdominal cavity : 

 its walls are very thick, and in addition to the simple tubular follicles of 

 the mucosa, there are some coiled tubular glands in the submucosa. 

 There are six pyloric appendages. The air-bladder is large and strong, 

 with a long terminal spur and 28 lateral arborescent appendages on 

 each side. 



The largest specimen is 11 inches long. 



Localities : off the Mahanaddi delta in 5 to 9 fathoms ; and off tho 

 Godavari delta in 4 to 5 fathoms. 



Family Traciiinid^. 

 An Uranoscopus which agrees in almost every detail with Uranos- 

 oopus cognatus (XJantor) was taken at two or three stations near shore ; 

 and Ohampsodon vorax (Gthr.^ was found three times in deep water. 



Ubanoscoptis cognatus.

Our specimens have not the pectoral rays tipped with scarlet ; and 

 the 15th dorsal ray seems to be only a branch from the base of the 14th. 

 Some have a small supra-ocular filament. There are 24 vertebrte. The
