Diagnoses of Four hitherto Undescribed Fishes
from the Depths South of the Faroe Islands.
By
R. Collett.
(Road at a Meeting of the Videnskabsselskab, May 3rd, 1904).
The three probably undescribed species of Deep-Sea Fishes
mentioned below, were oblained during the cruise of the fish-
steamer "Michael Sara", in June and July, 1902, conducted by
Dr. Hjort, who has kindly placed at my disposal the entire
collection of fishes made during that cruise and those of the
two previous summers, 1900 and 1901, (with the exception of
such species as are chiefly of economic interest).
A more detailed account of this collection will be published
during the course of the year in "Report on Norwegian Fishery-
and Marine-Investigations", Vol. III
Etmopterus princeps, n. sp.
Allied to E. spinax, but much larger; the scales not "seti-
form”, but forming a short and almost erect spine (the specimens
page - 4 -
are not in good state of preservation, and the diagnosis might
be completed with better material).
Diagn. Head rather broad; length of snout (from mouth)
less than the width across the gill openings.
Scales forming a short radiated spine, its height not ex-
ceeding the base of the scale, and allowing the skin to be every-
where visible between the scales.
Gill openings. The anterior wider than the posterior ones,
the width being about twice the diameter of the Spiracula.
Colour blackish brown; membranous margins of the fins
bluish.
Size large, total length reaching 728 mm.
Hab. Faroe Channel; Faroe Bank. Depth 750-1200 meters.
Temperature at the bottom about + 7° C.
