The end case exhibits the j^rotesciue fishes from deej) water, 

 ill which they occur to the surprising de])th of over 8,()(X) fathoms, 

 or more than '.V -j miles. They are usually soft in substance, 

 witli hu«ie heads and dwarfish bodies, and are often pro- 

 vided with illuminatin«i: orjz:ans like little electric bulbs, 

 which can be "shunted" off or on by the fish, and enable the fishes either 

 to see their neijihbors or to attract their jirey. A ^rouj) rej)resenting a 

 number of these fishes as they are sujDposed to appear in the gloom of the 

 I)rofound depths, lit up only by their luminous organs, is showTi in an 

 enclosure next to the Paddlefish (iroup mentioned above. 



Before the visitor has completed his review of the hall, he should 

 examine the two wall cases, on either side of the doorway, which explain 

 the characteristic structures of fishes of different groups, and the way 

 in which the groups are related to one another. In one of these wall 

 cases various kinds of fishes have been arranged in a genealogical tree, 

 and the lines and labels give an idea of their evolution.
