T he Zoology of the Marine Invertebrates of New Brunswick has 
been, in one section at least, well studied. The Island of Grand 
Manan, lying near the mouth of the Bay of Fundy, with the tides 
and currents of the Atlantic washing its shores ; having numerous 
outlying islands with sheltering bars and reefs, which thus give every 
variety of bottom, affords exceptional facilities for the study of 
marine life. That its advantages are appreciated by American 
scientists is evinced by the fact that not a summer now passes with- 
out one or more parties, either representing some university or work- 
ing upon their own account, visiting the Island for the purposes of 
dredging and study. Some years ago a very complete catalogue of 
the invertebrate life of the surrounding waters was prepared by Di*. 
Stimpson and published among the Smithsonian “ Contributions.” 
He enumerates some sixty-four (64) species of Radiates, one hundred 
and forty-two (142) of Molluscs, and one hundred and seventeen 
(117) of Articulates, many of which were new species. Friar’s Bay 
also, lying between Eastport and Campobello, and swept by the tide 
pouring through Lubec Narrows and around the North of Campo- 
bello, has been thoroughly dredged and the results published from 
time to time ; but with these exceptions the Zoology of the Marine 
Invertebrata of the Southern coast of Ncav Brunswick is compara- 
tively unknown. 
Passamaquoddy Bay, the “great pollock water” of the Indians, 
has never, so far as I have been able to learn, j^revious to this year, 
been sounded by the naturalist’s dredge. Lying at the South- 
Western corner of Charlotte Co., with a length of fifteen and breadth 
of seven miles, it receives the water of four rivers and many smaller
