4. On some new or imperfectly known Fishes of India and 

 Burma. "By Surgeon-Major Francis Day, Inspector 

 General of Fisheries of India. 



[Received November 25, 1872.] 



Amongst the numerous species of fish which I have lately obtained 

 at Bombay, Calcutta, or Kurrachee, the following appear to be un- 

 described or but little known. 



Gobius masoni, sp. nov. 



D. 6 | -j. P. 19. V. i- A. 10. C. 12. L. 1. 34. L. tr. 11 *. 



Length of head |, of caudal £, height of body ^ of the total 

 length. Eyes, diameter f of the length of head, 1 diameter from 

 the end of snout, and g a diameter apart. Upper profile of the head 

 rounded, its width equal to its height or to its length without the 

 snout. No crest on the head, glands, or barbels. Cleft of mouth 

 rather oblique, the lower jaw somewhat the longer ; the posterior 

 extremity of the maxilla extends to below the middle of the orbit. 

 Teeth, a large recurved canine on the outer side of an enlarged row 

 in the lower jaw. Fins : dorsal spines filiform, the longest two thirds 

 as high as the body below it ; second dorsal fin highest posteriorly, 

 where it equals that of the body ; anal similar to the second dorsal ; 

 caudal wedge-shaped ; ventral not extending so far as the vent, its 

 basal membrane well developed ; none of the pectoral rays silk-like. 

 Scales anterior to the middle of the first dorsal fin much smaller than 

 those on the remainder of the body, which are ctenoid and in eleven 

 rows between the base of the second dorsal and the anal fin ; they 

 are extended over the upper part of the cheeks and opercles. Colours : 

 deep olive, with numerous small blue spots along the side, each in 

 the centre of a single scale ; an ill-defined dark band passes from the 

 eye to the tail. First dorsal with its upper two thirds violet, tinged 

 with yellow, its lower third deeply spotted with black ; second dorsal 

 with a violet and yellow margin, its lower three fourths spotted with 

 black, most densely superiorly ; anal dark, with a few small round 

 white spots between some of the rays ; caudal darkish with irregular 

 blotches, and having its upper margin stained with yellow ; yentrals 

 nearly black, with an orange edging ; pectoral without marks. Under 

 surface of the throat black. 



Hab. Bombay. 



I have named this fish after my friend J. Wood Mason, Esq., of 

 the Indian Museum, Calcutta. 



Gobius ocellatus, sp. nov. 



D. 6 | i. P. 20. V. J, A. 10. C. 12. L. 1. 32. L. tr. 8. 



Length of head f , of caudal fin \, height of body \ of the total 

 length. Eyes somewhat superior ; diameter ^ of length of head, 

 1| diameter apart and also from the end of the snout. Head 



* By "L. tr." in the Gobies I signify the number of horizontal rows existing 

 between the origin of the second dorsal and the anal fin.
