ON THE DISTRIBUTION OF THE GENERA. 373 
Phyciculus : — The points at which species of this genus have been cap- 
tured support the idea of a strait from the Caribbean fairly well, and they 
favor that of one from the Mediterranean but little less. Panamic, off 
Lower California, in the Caribbean and Gulf to off New York, off the Cape 
Verdes and the Canaries, in the Bay of Bengal and off Japan, Australia, and 
New Zealand. 
Bregmaceros : — Such a range as that indicated by the localities Panamic, 
off Acapulco, Caribbean and Gulf, Arabian Sea, Bay of Bengal, China Sea, 
Philippines, and Amboyna, and middle of the Indian Ocean is entirely 
tropical and is favorable to an outlet westward from the Caribbean, but 
somewhat less so to one in the same direction from the Red Sea. 
Mucrurus : — There are few genera with broader ranges than appears in 
the following localities for Macrurus: Panamic to Bering Sea, Chili, Straits 
of Magellan, Hawaiian Islands and southward to New Zealand and Australia, 
Caribbean and Gulf of Mexico to Nova Scotia, Davis Straits, Iceland, Farées, 
Finmark, Norway, British Isles to the Mediterranean, Azores and Cape 
Verdes, Pernambuco to Patagonia, Arabian Sea, Bay of Bengal to Celebes, 
Japan and eastward to the mid-Pacific, Madagascar, and the Antarctic. 
Favors Arctic, Antarctic, or torrid routes from ocean to ocean about equally. 
Trachyrhynchus : —n its distribution there are as yet no locations near 
the Caribbean; the genus has been secured from the Panamic, south of 
Iceland, off the Farées, off Portugal, in the Mediterranean, and off New 
Zealand. 
Monolene : — Hardly any of the genera favor a Panamic strait, either by 
relationship of species or by localities, more than this one. The known 
range is from the Panamie to Mexico and from the Caribbean and the Gulf 
of Mexico to New York. 
Symphurus :— Both the list of localities given for this genus and the 
close affinities of the species favor either of the two straits under considera- 
tion. Species have been obtained in the Panamic to California, in the 
Caribbean to off New England and to Montevideo, in the Mediterranean to 
off the Soudan, and in the Bay of Bengal to the Arabian Sea. 
Slernoptyx : — Antarctic localities render the distribution of Sternoptyx 
less important in a discussion of outlets from the Caribbean and the 
Mediterranean than that of many of the other genera. The list includes 
the Panamic, off California, the Hawaiian Islands, the Caribbean and Gulf 
of Mexico to the Newfoundland Banks, the mid-Atlantic to off Morocco
