IN FEATHERS AND FUR.

It has a very heavy, long sort of a fringe all around the shell, of 
an orange color. This fringe is composed of tentacles, and is con- 
stantly in motion, twisting and waving about in the water. This 
lovely little creature has a curious fashion of making itself a sort 
of nest, by fastening together shells, bits of coral, sands, and other 
materials, by a silk thread, which it can spin, with* its. delicate little 
foot. 
Coral is the favorite material for the nest, and when done the 
droll little home looks like a rough heap of broken coral. But though 
rough outside, it is beautifully lined with silk hangings, and the 
delicate little beauty lives as comfortably as any one. Taken out 
of his nest, and put into a dish of sea w r ater, the Lima will swim 
about in a very lively way. He swims like the Pecten, by opening 
and closing his shells, thus^ making a jerky sort of progress through 
the water. 
Here's- another curious little 
fellow, who lives in two shells. He 
belongs to the Cock e family. Ycu 
see in this picture the little fellcw 
who lives there is at heme, and his 
(curious foot is stuck out. He has 
but one foot,, but that is as many 
as he wants. I don't suppose he 
would know what to do with two. 
He lives in. the sand and mud, just 
under the water on the sea-shore, 
and that odd little foot is a very 
useful organ,

he thrusts the 
into the sand, and then, contracting it into a kind of a hook, the 
whole animal is drawn a little way into the earth. Another jerk, 
and he goes farther in, and so he goes on till he is entirely buried, 
with the exception of a tube, which he keeps cut to breathe 
through. 
But that is not the only use of the foot. He can leap with it, 
and has been known to jump out of a boat after he was caught. 
To do this he bends his foot into a hook, presses it firmly against 
the board or ground, and straightening it out with a jerk, away he 
goes like a shot.
