Only ou the cruiacc of the Avadia arose any risk of confusion with haddock, 

 and here, more especially in the case of the southerly stations, where examples of 

 haddock ova were in the majority. 



The charts show very distinctly the distribution of the cod egg's. We find them 

 always over the banks, and as a rule in greatest numbers where the banks shelve down, 

 but never distributed over great depths. 



Cod larvae occur very sparsely; only on the ^Newfoundland banks have we at 

 Station 83 a fairly good yield of 216. the sizes here varving between 3 and 10 mm. 

 and ranging for the greater part between 4 and 6 mm., i.e., comparatively newly 

 emerged fry. 



Haddock larva; were found only on the cruises of the Acadia, especially the 

 second, off Nova Scotia and ou the Newfoundland banks. They are very few in 

 number ; only sixteen for both cruises together. The size varied between 3 and 15 mm. 



Cod and haddock have, as we know, a very wide area of distribution in the 

 northern hemisphere. The haddock ranges from the bay of Biscay as far as Spitz- 

 bergen; on the American side, Avhere, by the way, it is not so numerous, down to cape 

 Hatteras. 



In Euroi^ean waters, the haddock spawn from January to June. 



The cod has more or less the same distribution as the haddock, penetrating, 

 however, also down into tke Pacific. It spawns at the same time. Spawning has,
