180 nUSKY SKTJLPIN. 



the length of the second dorsal, its extent being two inches, 

 while in another fish of the same size it measured only 

 about half an inch. The snout in front of- the eyes in this 

 example with the partially lengthened fin, has also assumed 

 the protruded form of the acknowledged Yellow Skulpin. The 

 difference in colour was only that this example was pale, 

 without the dark tinge on the throat which is seen in the 

 fully-coloured Yellow Skulpin; while several specimens of the 

 Dusky Skulpin, with short dorsal rays, laid by its side, had 

 their colours, as described above, strongly marked. In the 

 month of December none of these fishes contained evidence 

 of roe or milt. The number of rays in the fins of both these 

 fishes is the same.
