154 MR. F. DAY ON NEW INDIAN FISHES. [Feb. 13, 



recurved as seen in the G. venenatus, G. viridipunctatus, and other 

 allied species ; but in the G. criniger " ses dents sont petites, nieme 

 les exterieures " (Cuv. & Val). " The teeth are minute, velvety, of 

 nearly equal length " (Cantor). "Teeth small" (Giiuther).

D. 6/i. P. 19. V. f A. i. C. 15. L. 1. 35-38. L. tr. 13. 



Length of specimens from 1 to 4 inches. 



Length of head \, of pectoral ^, of caudal |, of base of first 

 dorsal g, of base of second dorsal ^, of base of anal ^ of the total 

 length. Height of head ^, of body i, of first dorsal ^, of second 

 dorsal ^, of anal \, of ventral \ of the total length. 



Eyes directed upwards and slightly outwards ; horizontal diameter 

 1 of length of head, | of a diameter apart, 1 diameter from end of 



snout. 



Teeth villiform in both jaws, except an external slightly enlarged 

 row in the lower jaw, those in which are considerably recurved in- 

 wards. A few of those in the outer row in the upper jaw are 

 slightly enlarged. 



Fins. First dorsal generally highest anteriorly ; but in some speci- 

 mens the fifth spine is somewhat the longest. 



Colours. These vary, generally greyish brown, with some large 

 irregular blotches along the side, and a slight brownish line along 

 the centre of each row of scales. Under surface of cheeks and 

 jaws lineated with circuitous brownish lines. Cheeks dark brownish. 



Fins. Dorsal generally yellowish, with a greyish tinge, and having 

 several irregular whitish lines along its lower half, also a deep- black 

 blotch with a white margin usually between its fifth and sixth 

 spines. Second dorsal of the same colour, with several rows of irre- 

 gular white spots. Pectoral, ventral, and anal greyish, the last with 

 some white dots. Caudal dark grey, with some lines of dark spots. 



Cantor observes that G. sublitus cliiefly differs from G. biocellatus, 

 C. & v., in its dentition ; but I have fortunately obtained a large 

 number of specimens at Madras, and find that the dentition of the 

 two is identical. His other diagnostic sign, namely the filamentous 

 fifth spine of the first dorsal, is accidental in the specimen and by 

 no means uncommon. 



One very curious diseased specimen of this species was captured 

 November 15, 186/; it is covered with large, hard tubercles over 

 its body and the base of its fins, also over its tongue.
