602 Surface Fauna of the Bay of Fundy. 
it would be well to include them with true oceanic genera in this 
connection, I undertake this comparison with more enthusiasm, as 
it has been my good fortune to examine and publish notices of 
nomadic animals which have been collected in high latitudes by 
Lieutenant Greely, and since it has been possible for me to study 
the marine life of Grand Menan and the islands off the coast of 
New Brunswick.’ 
A study of the surface life of the Bay of Fundy reveals inter- 
esting facts in the theory of the Arctic relationship of the life of 
these regions. | 
Nomadic animals which live in the high seas, generally upon 
the surface of the ocean, are known as pelagic animals, and consti- 
tute what is called the pelagic fauna. While this fauna is pre- 
eminently the fauna of the ocean and is found best marked at a 
great distance from the land, it often happens that winds and cur- 
rents sweep its members into our bays and harbors, and we in this 
way become familiar with it. Like all large bays with open access 
to the ocean, the Bay of Fundy has a pelagic fauna. It is, in fact, 
the same or nearly the same as the pelagic fauna of the coast of 
Greenland. 
Animals which are strictly pelagic are never limited to the 
coast, to the littoral fauna, or to the sea bottom. They never become 
attached, but crawl about, or rest upon the sea floor, A large number: 
of marine animals have young which resemble pelagic organisms 
in these nomadic habits. They also wander about and are carried 
hither and thither by ocean currents independent during their youth 
of the coast or the sea bottom. As they reach maturity, however, 
they sink to the sea floor, and there remain, either attached or 
limited in their movements toa small area. These young or larve, 
as they are called, may also be included in the pelagic fauna as long 
as they preserve this free-swimming feature. This larval and 
adult pelagic fauna differs in different regions of the ocean, and 
that of the Bay of Fundy differs in a marked manner from that of 
the bays of southern New England. : 
A study of the pelagic fauna of the Bay of Fundy shows that it 
has a boreal character. While it is in many respects like that of 
1 I have already elsewhere (Bull. Mus. Comp. Zool., vol. xiii,, No. 
6) considered the boreal relationships of the medusan fauna of the Bay 
of Fundy.
