AMPHIPODA AND ISOPODA OF THE FIRTH OF CLYDE. 27 



Some of the tubes, which were suspected to be 

 those of an Annelid, were put into water over-night ; 

 and in the morning a few of the Amphipods were 

 found swimming free, which led to the discovery of 

 the occupants. The animal can swim about briskly 

 for a time, rolling itself up when it settles down to 

 rest. None of them were seen to return to their 

 tubes. 



The tubes are flat, of a soft leathery consistence, 

 chiefly composed of clay, and deriving strength and 

 flexibility from the secretion of the animal. They 

 are from one to two inches in length, are sometimes 

 bent more or less, and frequently have small lobes 

 or sacs projecting from the lower ends. 



When undisturbed, the creatures are seen to lie 

 with their head just so far out as to bring the red 

 eye into view beyond the margin of the tube, with 

 the antennae spread out, no doubt awaiting passing 

 prey.

Habitat. — Dredged off Skate Island, Loch Fyne, in 

 100 fathoms, bottom soft mud ; two only were met 

 with. 



Genus Phoxus, Kroyer.

Habitat. — Taken at the roots of Laminaria sacchar- 

 ina, in G fathoms, at the Tan Buoy, Cumbrae. This 

 species is very minute. 



In their description of the species, Bate and West- 

 wood appear not to have seen the eyes. These are 

 small, round, and white, having a few red spots 

 placed at regular distances near the circumference.
