Greenland to Cape Hatteras. It remains in deep water dur- 
ing the late autumn and winter, approaching the coast in 
May and June for the purpose of spawning, its annual 
appearance being very regular. The number.of eggs de- 
posited in one season by each female is said to be from five 
to six hundred thousand. After spawning they move north- 
ward, following the coast until they are checked by the 
coolness of the water, when they return, and in November 
seek the deep water again. When spawning they do not 
take the hook ; they are then lean; but at the time of their 
departure from the coast they are fat and plump. (Blake.) 
The eggs of the mackerel as well as of the cod are so light 
as to rise to the surface, where they develop. Allied to the 
mackerel, though of great size, are the horse-mackerel and 
the sword-fish, whose upper jaw is greatly prolonged.

The singular Anabas of the East Indies is the representa- 
tive of a small group of fishes called Labyrinthici or laby- 
winth-fishes, in allusion to a cavity on the upper side of the 
branchial cavity on the first gill-arches, containing a laby- 
rinthine organ, which consists of thin plates, developed 
from the upper pharyngeal bones, enabling the fish to live 
for a long time out of water. Anabas scandens Cuvier, of 
the fresh waters of India, will travel over dry land from one 
pond to another, and is even said to climb trees by means 
of the spines in its fins. 
Near the head of the order stands the cunner (Zautogola- 
érus adspersus Gill), whose anatomy is represented by Figs.
