legs are slender and about five inches long. This shrimp ranges 

 from New York to Brazil, hut is found also among the tropical islands 



of the Pacific. It 

 lives among the cor- 

 als, the male and fe- 

 male swiramingside 

 by side. The eggs 

 are of a delicate 

 green color, and are 

 carried about at-

 minal appendages 

 of the female. When

 The Feather-Footed Shrimp, (Mysis stoiolcpis, Fig. 57 J, is a 

 little translucent brown creature al)oiit one-half an inch long and 

 may be recognized by the feathery hairs on its legs and antennae, 

 large eyes, and spines on the sides of the body. It has no claws, 

 and the abdomen is " brohen-backed," and somewhat longer than 

 the forward part of the 1)ody. It is most abundant on our coast in 

 winter in shallow muddy or grassy places, and often occurs in great 

 swarms.

 occupying shells has profoundly modified the structure of the body. 

 The abdominal appendages are reduced or wanting, and the sixth 

 pair have become hook-like, allowing the crab to anchor itself with- 

 in the shell. The abdomen is twisted so as to fit into the coils of 

 the shell, while in some species all of the legs on one side are shorter 

 than those of the other, thus giving the body a one-sided api^ear-

 crust, and the eyes are mounted upon long stalks. When disturbed
