604 Surface Fauna of the Bay of Fundy. 
inhabitants of the Gulf of Mexico. As the study of animals which 
are not nomadic teaches that those of the Bay of Fundy are most 
closely allied to the inhabitants of the colder waters of the Arctic, 
soit is with the surface life. Both tell one and the same story, that the 
assemblage of life in the sea which constitutes the fauna of the Bay 
of Fundy is Arctic in its affinities. To demonstrate the Arctic 
character of the free-swimming life of the Bay of Fundy would 
seem to necessitate a minute comparison of faunal lists from the two 
localities. It is not wholly necessary for our present purposes, 
however, to make such an extensive comparison. Some of the 
more striking instances of floating boreal life will suffice. 
Of all floating animals the jelly fishes are well suited for this 
study. Among the Medusze we have marine animals, as well known 
as any, from which to test our theory. The following may be 
mentioned as some of the Medusæ of the Bay of Fundy which are 
markedly Arctic. The large and beautiful Cyanea arctica, one of 
the most stately forms of discophorous jelly fishes, is pre-eminently 
an Arctic genus. Callinema, first described by Professor Verrill, 
another large Medusa of the same group, and has never been 
seen south of Cape Cod. Among Hydromeduse the beautiful 
Turris episcopalis is boreal in its distribution, and rarely gets south of 
the coast of Maine. Staurophora and Halopsis are northern genera. 
The beautiful “ sea necklace,” Nanomia cara, one of the most exqui- 
site genera of marine animals, has been seen in the icy waters of 
Robeson’s Channel by Arctic navigators. It is rarely seen south 
of Cape Cod, in Narragansett Bay, but at Grand Menan hundreds 
of specimens, some of which were four feet in length, were taken 
from the landing places, and at other points on the shore. 
If we, in fact, take the faunal lists of the Meduse of the Bay of 
Fundy and compare them with those from Greenland and neigh- 
boring waters, we find, as far as our knowledge goes, a strong 
resemblance between ie medusan life in the two regions. of 
course there are genera occurring in the waters of Greenland 
which are not to be found in the Bay of Fundy, and vice versa, but 
that does not change a belief in a general statement that the marine 
animals of the two localities resemble each other in facies. If we
