TAIL-SPOTTED GOBY. 
Gohius attenuatus, C. 
This species is found in the same places with the two last 
named, to which, chiefly on account of its colour, it bears 
considerable likeness; but it is much more rare than either of 
them. The length scarcely exceeds two inches, and the general 
shape almost uniformly slender from head to tail. The snout 
is even shorter in front of the eye than either of the others, 
but the eye is not quite so high. Under jaw protruded. The 
dorsal fins are further apart; second dorsal and anal low, and 
the latter begins opposite about one third the length of the 
former, both ending together. Tail straight. In the example 
described the ventral fin was divided, but this may have been 
produced by accident. 
The colour was uniform chesnut brown, lighter on the belly; 
dorsal fins and tail with reddish bars; anal fin pale; a dark 
ocellated spot at the root of the tail, but no mark or stain of 
this sort on the side, as in the other tail-marked species.
