" The colour was a uniform liglit-bluisli grey, skin covered 
with minute hooked spines, hooks pointing backwards. A 
row of mucous ducts extended from the tail to the head, 
their apertures, four-tenths of an inch apart, forming the 
lateral line which branches off at the head into symmetrical 
curves. These ducts are about half an inch in length, and 
communicate obliquely with a longitudinal canal just under 
the skin, lined with a dark pigment membrane. On dissect- 
ing the fish, the liver, consisting of two lobes, each 5 feet in 
length, weighed 35 pounds.

" In the stomach was found a pultacious mass, along 
with portions of the cat-fish, cod, and haddock, and a large 
cod-hook wath a part of snood attached. The usual spiral 
valves were observed in the intestine. The claspers at the 
base of the ventral fin showed this to be a male fish ; and 
an elongated testis, covered by a delicate membrane, ex- 
tended on each side of the spinal column the whole length 
of the abdominal cavity. Some of the more interesting por- 
tions of the viscera are now in good hands, — Mr Turner, 
who was present at the dissection, having possession of
