210 BULLETIN OF THE 
I have had in mind since that time a new visit to these localities to 
gather materials for the publication of a monographic paper on the 
medusz of the Bay of Fundy, but have been unable to make the ne- 
cessary collecting trips for its completion. It is now thought best to 
publish some of the more interesting observations which have already 
been made, as aids to those who may make a more exhaustive local 
study of these animals, or as a preliminary to a more extensive exami- 
nation of animals of this group from these localities. 
While the majority of the medusz here mentioned are from Eastport, 
Maine, and Grand Manan, New Brunswick, a description of a new genus, 
Hydrichthys, from Newport, R. I, is added.* This strange genus is 
parasitic in its hydroid stage on the sides of an osseous fish, and besides 
the unique parasitism presents us the anomalous condition of an at- 
tached hydroid closely related to the well-known Velella and Porpita. 
The form of Nanomia, the anatomy of Callinema, and the peculiarities of 
the various other medusz here mentioned from the vicinity of Grand 
Manan, show how characteristically boreal this medusan fauna is, and 
how much it differs from that of Narragansett Bay. They show how 
rich the field is for an extended research in this region in this kind of 
marine study.f 
The short visit which was made to Grand Manan, and the collecting 
trips to Eastport in 1885 and 1886, have shown me that the medusan 
fauna of the Bay of Fundy and Passamaquoddy Bay, near these places, is 
very characteristic. It differs markedly from that of Newport, and is 
distinctly boreal in its affinities. While this paper was in preparation the 
author has had occasion to study the medusan fauna of the Arctic Ocean, 
and to publish notices of jelly-fishes collected by Lieutenant Ray and 
General Greely in high latitudes. It has been noticed in carrying on 
this work simultaneously that there is a marked similarity in the fauna 
of the Arctic and that of the Bay of Fundy, and it may be said that the 
* This curiously modified hydroid was captured during the summer session 
(1887) of the Newport Marine Laboratory. 
7 The author would here add a notice of his own experience to that of others as 
to the advantages of Grand Manan for marine zodlogical work. While many, per: 
haps a majority, of those who have studied zodlogy in this place, have spoken of 
its many advantages for dredging and shore collecting, few have tried surface 
fishing in these waters. I had been led to suppose from certain sources, that 
revelations with the Miiller net would be small in these localities, but I find 
Grand Manan and Eastport among the best localities which I have visited on the 
New England coast for the collection of pelagic and “surface animals ” with the 
dip-net.
