poidæ, viz., the Oncæidæ, Sapphirinidæ and Corycæidæ. Of course 
the animals which at times may be infested by the present Cope- __ 
pod must also be pelagic in habits; but of what kind they are, it — 
is impossible at present to decide. At my request, Mr. Nordgaard 
informs me, that in the same gathering in which the present 
Copepod was found occurred, in addition to Calanoida and other 
pelagic Crustacea, some small Medusæ and Ctenophora, as also 
plentiful of Chætognathi and Pteropoda.
