EUROPEAN ALECTO. 
Rays simple; tentacules of the back very slightly rough- 
ish, the joints elongate, contracted at their middle part, 
the last internally produced. 
This species is found in the Kuropean ocean, and is not 
uncommonly dredged up on the south coast of Devonshire. 
If it be the same with 4. decacnemos of Pennant, of which 
there is little doubt, it likewise inhabits the western coast 
of Scotland.
