REPORT OF COMMISSIONER OF FISH AND FISHERIES. [142] 



RECAPITULATION. 



The following is an approximate statement of the number of species 

 and subspecies, now known, belonging to each of the principal faunal 

 areas. No species is counted twice, but in case of the numerous species 

 which range over several faunal areas each is referred to that area 

 which is supposed to be most properly its home, or to that in which its 

 occurrence has been longest known. In regard to many species such 

 an assignment is simply arbitrary, and in this fact lies the chief ele- 

 ment of error in the following list. Thus many Arctic shore fishes 

 belong to the Bassaliau fauna of New England, while many West In- 

 dian species occur northward more or less frequently as far as Cape 

 Cod. No faunal region on our coast is bounded by sharp lines:
