SQUILLA. 
157 
legs with, six long teeth ; abdomen above with eight longi- 
tudinal rows of small prominent crests. 
Cornwall, first recorded as found in the British seas by 
Professor Bell, who obtained a specimen from Mr. Couch, 
which was procured about a couple of leagues from the 
shore, where the bottom was rocky with some spots of 
sand. When alive it is of a very pale yellowish-grey. 
Mediterranean specimens attain the length of six or seven 
inches. 
Dr. Lukis found on the coast of Guernsey a species of 
Phyllosoma , which he has described under the name of P. 
Sarniense. The species of this remarkable genus, when 
alive, are transparent like crystal, and are very flat ; the 
legs are very long and slender, while the eyes are on long 
stalks. A species of the genus has been met with in the 
Mediterranean, but it is in the tropical seas that these 
curious creatures occur most abundantly ; the eyes are blue, 
and contrast 'strikingly with the glassy transparency of the 
rest of the body. Dr. Lukis informed me in the summer 
of 1856, that three living specimens of this glassy Stomajood 
had been taken floating near the surface.
