240 POPULAR HISTORY OF THE AQUARIUM. 



Limpet wliich was placed iu his jar. Living in this se- 

 eluded style, and seldom moving about in search of prey, 

 the poor little animal would find it difi&cult to procure the 

 necessary food, if it were not for an instrument with which 

 he is provided. The outer foot-jaw is largely developed, 

 and furnished with a network of hairs, which, when thrown 

 out, form, in returning, a spoon-shaped sieve, which, letting 

 the water escape, brings into the mouth all the animalcules 

 within its grasp. I should have said the onter pair of foot- 

 jaws, for there is a pair of them. They are shaped like 

 scythes, and used alternately. Those who have seen the 

 movement describe it as beautiful, and resembling those of 

 the cirrhi of the Balanns ; but, in the latter case, the action 

 is simultaneous in both members. 



Galathea strigosa. 



A very pretty and merry Aquarian, with a form between 

 that of Crabs and that of Lobsters. It uses the tail freely, 

 jerking its body up and down the sides of the tank, and 

 looking as if it had the power of crawling on perpendicu- 

 lars. It is very prettily marked with stripes of blue between 

 the red.
