A CORNISH FAUNA. 
The Sandy Eay {Raia circulwris). I record this Eay in deference 
to the authority of Mr. Conch, hut I much doubt whether it 
is not an accidental variety of the Homelyn. 
The Torpedo {Raid, torpedo). The Cramp Eay. The Electric 
Eay. Is not uncommon, and yet is rarely observed, because 
most fishermen cut it away as soon as they see it. 
The Sting Eay {'Irygon pastimca). The Eire-flaire. Is of rare 
occurrence. 
The Eagle Eay {Myliohatis aquila) is recorded as having occurred 
once off the coasts of Cornwall. 
PETROMYZIBM . — (the Lampreys.) 
The Sea Lamprey {Petromy%on marinua.) Common. 
The Lampem (P. A river fish. Is said by Mr. Couch 
to be “ Common,” and no doubt it is so in the eastern part 
of the county. With it, should, apparently, go the Silver 
Lamprey and Planer’s Lamprey ; but I am now making my 
conclusions from written descriptions and not from observa- 
tion, and cannot therefore speak with confidence. 
The Mud Lamprey {Ammocmtes Iranohialis). The Pride. Blind 
Lamprey. Common. 
The Mixine {Oastr'olranohua cmcua). The Borer. The Hag Pish. 
Eare. 
Lancelet {Amphioxus lanceolatus). A tiny fish, and very rare. 
All small fish of the deep sea are rare. They escape 
observation. 
I have now closed my list, having foEowed, as I have before 
said I should, as closely as possible the classification adopted by 
Mr. Couch. The advantages to be gained by my doing this 
seemed to me to outweigh the advantages of a more modern 
method. I have cited, wherever I could, the scientific names 
given by TarreE as rendered by Couch. Where this has been 
impossible, I have added the name of the naturalist whose nomen- 
clature I have adopted. A list of this sort can never be perfect, 
and if I have fairly foEowed in the footsteps of my predecessor 
(who did the work; I have but revised it) I shaE be quite 
content. 
It seems to me that a practical value of local icthyology lies 
in its teaching us of our supply of fish as an article of food, and 
I can say with confidence that very few people, indeed, know the
