AMPHIPODA AND ISOI'ODA OF THE FIRTH OF CLYDE. 70 



animals seem to depend more for their safety on 

 lying motionless than on trying to escape. I have 

 seldom failed to find them on the pier at Millport 

 by brushing the wall with a hand-net. I have also 

 met with them among the legs of a dead crab. 

 This species has been taken at Falmouth by Mr. W. 

 P. Cocks ; Plymouth Harbour, under stones, Bate 

 and Westwood ; coast of Berwick, the late Dr. 

 Johnston.

Habitat. — Taken under stones between high and 

 low water, Portloy, Cumbrae ; and among algae 

 scraped off the pier at Millport. These small 

 animals can be best searched for by taking the 

 stones home and putting them into a shallow vessel, 

 with sufficient water to cover them and admit of 

 their surface being viewed through a pocket -lens. 

 After remaining a few hours, small animals come 

 out of the crevices and creep along the stone, or 

 swim through the water, or crawl up the side of 

 the vessel, where they can at leisure be readily 

 detected and picked up.

Habitat. — In the month of March no fewer than 

 nine were taken on stones near low- water at Portloy, 

 Cumbrae. My captures of this species had hitherto 

 been chiefly at the roots of Laminaria saccharina.
