pointed and not longer tlian the eye. The ventral fin nearly 
reaches the long and prominent anal papilla ; dorsal fins separated 
from each other by a short interspace. Reddish-olive, crossed hy 
five broad blackish bands, of which the first crosses the parietal 
region, the second corresponding to the anterior dorsal fin, the third 
and fourth to the posterior, and the fifth occupying the end of the 
tail •, fins marbled with blackish ; lower fins whitish. 
This species is allied to Coitus huhalis^ but distinguished by the 
lesser development of the armature of the head ; the spines, which 
in C. huhalis project as sharp points beyond the skin, being 
covered in the present species by the skin ; also the parietal area 
has a different shape. Our specimen has only six anal rays, whilst 
the Scandinavian authors ascribe eight or nine to this species. On 
account of this discrepancy, I felt some doubt as to the correctness 
of my determination, which, however, was confirmed by Dr Liitken, 
who kindly acceded to my request to compare the Scotch specimen 
with those in the Copenhagen Museum.* 
This is a new addition to the fish fauna of Great Britain. The 
specimen is 2| inches long, and the species generally seems to be 
much inferior in size to the other British species of the genus. It 
was caught off Ardrossan, at a depth of between 15 and 30 fathoms, 
in the month of July. Previously this species had been found on 
various parts of the coast of Norway and near the Faroe Islands. 
Coitus scorpius. Large Bullhead. 
Two immature specimens, between Cloch Lighthouse and Whit- 
ing Bay, from 15 to 30 fathoms. July. 
One immature specimen, between French and Kilbrennan Sound, 
10 to 14 fathoms. March. 
Coitus huhalis. Long-Spined Bullhead. 
A very young specimen; in the Mull of Cantyre, from 60 
fathoms. February. 
An immature specimen ; Sound of Sanda, 20 fathoms. March. 
* Whilst this paper was passing through the press, I received a second 
specimen, If inches long, from the Sound of Sanda, 20 fathoms, which has 
eight anal rays.
