ON THE DISTRIBUTION OF THE GENERA. Sine 
Pacific to Bering Sea, and from Nova Scotia to Davis Straits, to north of 
Iceland to Norway and to Finmark. 
Lycodopsis :— Has a range, in present determination, from the Panamic area 
northward to California, Puget Sound, the Aleutian Islands and to Japan. 
Lycodes : —Tnhabits the Pacific from the Panamic to California and 
Bering Straits, and the Atlantic from off Cape Cod, Newfoundland, and 
Greenland to north of Iceland, Norway, Finmark, and to the Kara Sea; also 
found off the Azores, and the Cape Verdes, and in the Straits of Magellan. 
On the charts the distribution of this genus in a measure suggests extension 
of range from the Atlantic through the Arctic and Bering Straits into the 
Pacific and down the western coasts of North America. 
Phucocetes : — Thus far identified only from two localities, off the Bay 
of Panama and in Magellan’s Straits. 
Lycodapus : — Now known from the Panamic, Bering Sea, and off 
California and Lower California. 
Lepophidium : — With a range including the Panamic to California, and 
the Caribbean and Gulf of Mexico to South Carolina and to Bahia, Lepo- 
phidium is one of the best supports of the theory of a transisthmian 
water-way. 
Mixonus : — The small number of the localities, Panamic, off the mouth 
of the Amazon, and off the Canaries, in connection with the great depths 
at which the species are found, raises doubt whether the genus if better 
known would support the idea of a Panamic connection with the Atlantic 
as well as the positions of the ascertained localities would indicate. 
Dicrolene: —In evidence from the Panamic to Mexico, from the Carib- 
bean and the Gulf of Mexico to off New York, off the Canaries, in the 
Arabian Sea and the Bay of Bengal. In its known distribution this is one 
of the best of the genera to be used in confirmation of the theory of a 
passage westward from the Caribbean, as also of one eastward from the 
Mediterranean. 
Porogadus : — This genus occurs in the Panamic, in the Gulf of Cali- 
fornia, off New York, off North Australia and off Borneo. It has not yet 
been identified from the Caribbean. 
Monomitopus : — Another of the genera most available in discussions of 
probable mid-Atlantic connections with the Pacific and the Indian Ocean. 
Reported from the Panamic, the Caribbean and the Gulf of Mexico, the 
Canaries, the Azores, the Arabian Sea, and the Bay of Bengal.
