the admiring observer. The Bullfrog Bometimes attains the 

 length of twelve inches, though the common size is from 

 four to six. It is not this species, but another, the Spring 

 Frog (liana fonlinalis), that is eaten as a delicacy, and, 

 nnlike the Bullfrog, it is herbivorous. If we intend to keep 

 frogs at all in our Aquarium, we shall find the prettiest, 

 especially in its young state, to be the Marsh Frog (liana 

 paluslris). It is also called the tiger, leopard or pickerel 

 frog. 



The Water Lizard (Triton millcpunctatus), crimson-spotted 

 Triton or Eft, is found all over the State of New York, 

 especially in mountain brooks and lakes, and is capable of 

 withstanding a very low temperature, as it has been 

 observed under ice an inch thick. The female is entirely 

 smooth, and the male, in breeding seasons, is furnished with 

 a brilliant coat, and wears a crest upon his back, as is 

 seen in PL VI., Fig, 2. This crest disappears later in 

 the season. The newts are intelligent animals ; indeed, 

 more so than fish, and arc easily tamed. There are 

 several other species found in this State, but the above 

 is the most common. When we intend to keep these 

 creatures, it will be found best to have a portion of 

 rockwork projecting above the surface of the water 

 so that they may get out into the air, as they are fond 

 of doing. Another common New York species, the Sala- 

 mandra rubra of naturalists, may be introduced into an Aqua- 

 rium with advantage, as it is only about five inches long 

 and of a bright crimson, spotted with black. Its color, which 

 very much resembles that of the gold-fish, contrasts 

 well with the darker species and the green vegetation.
