Of the 600 new species of Crustacea, about 200 are oceanic 

 species, of many of which, even the genera or families are un- 

 known. The ocean swarms with minute Crustacea, and it is 

 seldom that a hand-net is thrown in good weather without 

 bringing up some novelty. In some seas they are so nume- 

 rous as to colour the ocean red over many square miles of sur- 

 face, as was observed off the South American coast, near Val- 

 paraiso. These are the red or bloody waters that have been de- 

 scribed. When thus numerous, these animals are often called 

 whale's feed ; and it is believed that they are actually the 

 food of the " right whale." Each animal is not over a 12th 

 of an inch long ; yet they swarm in such numbers as to afford 

 subsistence to these monsters of the deep. The fibrous net- 

 work of whalebone, in the roof of the whale's mouth, is fitted 

 to strain out these animals from the water, which passes 

 through, and is ejected by the spout-holes. Many minute dis- 

 sections have been made of these and other Crustacea, and 

 some interesting physiological facts brought to light. As the 

 species are often transparent, nearly all the processes of life, 

 even to the motion of every muscle and every particle that 

 floats in the blood, are open to view. 



The Anatifa (a species of barnacle) has been traced through 

 its metamorphoses, from the young state, when it resembles a 

 Cypris, and swims at large with distinct compound eyes, to 

 the adult animal ; and its connection with Crustacea is placed 

 beyond doubt. 



The collection of corals at the National Gallery is one of 

 its principal attractions. The great beauty and variety of these
