376 DEEP SEA FISHES. 
The genus has been located in the Panamice, off Mexico, off California, in the 
Caribbean, in the Gulf Stream off the eastern United States and the Grand 
Banks, southeast of Greenland, European coasts to the Mediterranean and 
the northwestern coasts of Africa, off the Azores, in the Bay of Bengal, and 
north of Australia. 
Halosaurus : — Important in its bearing on the Central American connec- 
tion, remote as concerns that of the Mediterranean, and fair in relation to 
migrations from ocean to ocean by way of the Antarctic. The locations 
are the Panamic, the Caribbean and the Gulf of Mexico to off New Eng- 
land, the mid Atlantic, the Azores and Cape Verdes to Gibraltar, the 
Arabian Gulf, the Bay of Bengal, off the Philippines and Japan, and in 
the Antarctic. 
Notacanthus : — About equally remote in its bearings toward migrations 
from or to the Atlantic or the Pacific by way of either the Arctic Ocean, the 
Antarctic, or a Central American strait. The localities include the Panamie, 
off South Carolina to the Grand Banks, south of Greenland and Iceland, off 
the Canaries, west of Magellan’s Straits, off New Zealand, and off south- 
western Australia. 
Uroconger : —Good evidence concerning a Central American strait, and 
fair in relation to that from the Mediterranean eastward, credited to the 
Panamic, the Caribbean and the Gulf of Mexico, the Canaries, Arabian 
Gulf and Bay of Bengal to the China Sea, Borneo and New Guinea. 
Congermurana : — Though it extends far toward the south the distribution 
of this genus in the main favors both of the straits with which we are here 
concerned ; the following localities are on record: Panamic, Gulf of Califor- 
nia, Hawaiian Islands, Caribbean and Gulf of Mexico, mid south Atlantic, 
Mediterranean Sea, Bay of Bengal, Japan, East Indies, Australia, the Fijis ; 
New Guinea, New Zealand, and the Antarctic. 
Ophichthys : — Accepting the genus in its more inclusive sense it may be 
placed with those which are used to establish the former recent existence of 
straits eastward from the Panamic and from the Mediterranean. The locali- 
ties are numerous; the range includes the Panamic to southern California 
and to southern Chili, the Caribbean and the Gulf of Mexico to Cape Hat- 
teras and to Montevideo, off the entire coast of Africa, the Mediterranean, 
the Arabian Gulf, the Bay of Bengal, Japan, East Indies, Australia, the 
Fijis, and other localities of the Indian and western Pacific Oceans. 
Cryptopterus : — Being shoal water species and very closely allied on the
