248 FISHES OF THE FIRTH OF FORTH. 



shore. The bipunctatus, independent of external charac- 

 ters, differs widely in habits from the rest of the gobies. It 

 frequents the irost rocky situations, where fun grows in 

 the greatest abundance, and is never found reposing on the 

 sandy bottoms, like the rest of its congeners. It keeps but 

 a short distance from below the surface of the water, appa- 

 rently in a motionless position, assuming, in this respect, 

 much the habits of the Stickleback ; when approached, it 

 gradually lowers itself in the deep, and soon disappears, 

 by making short, though rapid, darts among the fuci which 

 it delights to frequent. 



This species is easily recognised by having more rays in 

 the first dorsal fin than the other British gobies possess. 

 The G. niger, G. minutus, G. unipunctatus, and G. gracilis, 

 have six rays in the first fin. G. albus* has but five, where- 

 as the G. bipunctatus has seven in that fin.
