Bell “dedicated the species to that indefatigable and acute

This species was taken first by Mr. Couch on the coast of 
Cornwall, and Professor Bell is indebted to him for a knowledge 
of it. It was found “ about two leagues off, where the bottom 
is rooky with spots of sand.” 
Squilla desmabestii. — Risso ; Edwards ; Bell, Stalk-eyed Crust, 
p . 354. 
Mr. Couch in his Cornish Fauna of 1 868 records this species

he says that it seems to be the species alluded to by Pennant 
and Turton, under the name of S. mantes.
