310 ACCOUNT OF A RIBBON FISH. 
This specimen is dft. 5in. long, and has Ift. maximum depth. 
The body was of a silvery gray, and the dorsal fin and tail red. 
Another example of the occurrence of the Deal Fish is given 
by Mr. Charles St. John, in his Field Notes and Tour in Suther- 
landshire. 
The following description is quoted from that work :—“ Length, 
3 ft. 6 in. ; depth, 7 in. ; greatest thickness, between half and 
three-quarters of an inch ; colour, bright silver, with one very 
thin crimson fin running the whole length of the back. The 
tail very transparent, fan-shaped, and of a bright crimson. A 
large flat eye and a small mouth, which the fish had a peculiar 
power of elongating to a considerable extent.” We have seen a 
very good coloured drawing of this individual by Mr. St. John, 
and understand that it was taken alive, hooked through the back 
by a common haddock hook.
