Station 893; 372 fathoms; one specimen. 
N. monstrosa, the type of this remarkable genus, and heretofore the 
only known species, was described from a single specimen, wanting 
most of the antennule and antenne, dredged in Christiania Fiord, in 
20 to 30 fathoms; and G. O. Sars has recently recorded a single muti- 
lated specimen, dredged in 1,215 fathoms, between Norway and Iceland, 
by the Norwegian expedition of 1876.

Syscenus infelix Harger, Marine Isopoda of New England, Report United States Fish 
Commission, vi, for 1878, p. 387, 1880. 
Stations 893 to 895; 238 to 372 fathoms. 
The following tabular synopsis of the known geographical distribution 
and the bathymetrical range, as far as ascertained by the investigations 
on our own coast, gives the principal facts in regard to the distribution 
of the species, and it will also serve as a condensed list of the species 
enumerated in the foregoing pages. In the first column the species are 
checked which are known to occur in the Straits of Florida or anywhere 
in the Caribbean region; in the second, those known in the shallow 
waters (under 30 fathoms) of the south coast of New England; in the 
third, those known from any part of the region from Cape Cod to 
Labrador; in the fourth, those known to occur in Greenland; in the 
fifth, those known on the coasts of Northern Europe or in the eastern 
part of the extreme North Atlantic; and in the sixth, those known from 
the Mediterranean. 
* The Isopoda have been placed in Mr. Harger’s hands for determination, but he has 
very kindly identified for me the few species here enumerated, which, however, are 
only a part of the whole number obtained.
