First lesson in zoology : adapted for use in schools . ecunner (Tautogo-labrus adspersus), whose anatomy is represented by Figs.139, 140. Passing over the tautog, the voracious wolf-fish{Anarrhichas), the blennies (BlennidcB), iu which the bodyis long and narrow, and viviparous eel-pout (Zoarces), thecottoids or sculpins, and a number of allied forms, we come TEE BONT FISHES. 163 to the hake {Merlucius Ulinearis), the haddock (Melano-arammus mglefinus, Pig. 167) and cod {Gadus morrhua, Fig. 168), all of which extend northwards from Cape Hat-teras, the cod abounding on both sides of the Atlantic, being a circumpolar fish. The cod does not, as formerlysupposed, migrate along the coast, but seeks the cool tem-perature to which it is adapted by gradually passing in theearly summer from shallow to deep water, and returning asthe season grows colder. It visits the shallow water ofMassachusetts Bay to spawn about the first of NoTember, and towards the last of the month deposits its eggs.

The eggs laid by the cod rise to the surfaceof the water, on which they float. The young fish hatchon the New England coast in twenty days after they are ex-truded. The cod is the most important of all the food-fishes, whether we consirl^r the number taken or the amount ofcapital involved in the cod-fishery. It abounds most on theGrand Banks of ^Newfoundland. The breeding habits ofthe haddock, hake, and pollock are probably like those ofthe cod.

In these fishes the body is very unsymmetrical, thefish virtually swimming on one side, the eyes being on theupper side of the head.
