ON THE DISTRIBUTION OF THE GENERA. 373 



Phi/dcuhs : — The points at which species of this genus have hoen 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. Panumic, 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. 



Brcgmaccros : — Such a range as that indicated by the localities Panann'c, 

 off Acapuico, 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. 



Macruriis : — 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, Faroes, 

 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. 



Trachyrh^nchus : — In its distribution there areas yet no locations near 

 the Caribbean ; the genus has been secured from the Panamic, south of 

 Iceland, off the Faroes, off Portugal, in the Mediterranean, and off New 

 Zealand. 



Monoleiic : — Hardly any of the genera favor a Panamic strait, either by 

 relationship of species or by localities, mcn'e than this one. The known 

 range is from the Panamic to Mexico and from the Caribbean and the Gulf 

 of Mexico to New York. 



Si/mplmrus : — 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. 



S/eniojJtyx : — 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, oft' California, the Hawaiian Islands, the Caribbean and Gulf 

 of Mexico to the Newfoundland Banks, the mid-Atlantic to oft' Morocco
