" The colour was a uniform light-bluish 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 with 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
