NOTE— FISHES. 



Occurrence of the Short Sunfish and Torpedo off the East Coast.^ 



A remarkably fine example of the Short Sunfish ( Oi-tliagorisciis niola L.) was brought 

 into Grimsby recently, caught in the North .Sea. Also a Torpedo {Torpedo 

 hebetans); this last taken in a trawl from the .Silverpit, off the mouth of the 

 Humber. It measures 18^ in. in length, by 10 in. at its greatest breadth. On removing 

 the skin the two batteries, or electric organs, were exposed on each side between the 

 head and pectoral fins. These have, superficially, a honeycomb appearance, being 

 formed of vertical hexagonal cells, filled with a clear gelatinous substance — these 

 organs are connected with the brain by nerves of extraordinary size and capacity. 

 Both these fish are now mounted in the small museum attached to the station of 

 the Marine Fisheries Society at Cleethorpes. — ^Joiin Cordeaux, Great Cotes, 

 Ulceby, Jan. 13th, 1890.
