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.
