corner of the eye, passing over the nostrils to the end of 

 the nose, where it meets a similar streak on the other side ; 

 on the front of the arm, near the shoulder, is a black streak, 

 which is found in all the varieties of the animal ; the lower 

 extremity of the back is marbled with black, white, or 

 yellow; sometimes the colour of the back is grey or brown. 



Var. B. Differs from the foregoing by the absence of the 

 yellow gold lines on the back. 



Var. C. Common in Italy, Sicily, Provence, and Spain. 

 Has all the upper surface chestnut-red, with brown marks, 

 more or less apparent, and is probably the " Sana mari- 

 tima" of Bisso. 



It passes most of its time in the water, and is found in 

 vast numbers in many marshes and ponds. Its loud croak 

 is known to all European travellers. In many parts of the 

 Continent, such as Prance, Italy, and Germany, its flesh is 

 considered peculiarly wholesome and delicate food. The 

 spawn is iisually attached to plants at the bottom of the 

 water, and is seldom seen on the surface. 



This Prog is found all over Europe, except in the British 

 Islands; throughout the North of Asia to Japan, and in 

 Egypt.
