“Eare. Mr. Oouch says that this is the only species that he 
has met with, and Dr. M. Edwards thinks that the others named 
are Only varieties. The other two are in the AthenEeum at 
Elymouth.” 
It has been taken at Scarborough, and is rare in Ireland.

Bell says, “The male of this species so nearly resembles that 
of E. hryerii that without careful examination they may readily 
t)6 mistaken for each other. The principal distinctive charac- 
ters are to be found in the form and proportions of the antennae, 
^nd the size of the granulations on the surface. 
This is the most rare of the British species of Ebalia. It was 
discovered by the indefatigable and unfortunate Mr. Cranch in 
Elymouth Sound, where, according to Leach, it was afterwards 
observed in considerable numbers.

“Common in the stomachs of fishes, chiefly Cod fishes and 
common Pays, from the depth of 20 to 60 fathoms. They must 
c-bound at these depths, as I have found more than thirty in a

cession was found to contain them.’' 
It has been recorded from the north of Scotland, and on the 
Irish coast.
