species derived from distant regions, are, as Goode has pointed out, 

 powerful and rapid swimmers. Few of the species which have been 

 described as peculiar to Bermuda have remained so long. Both Stole- 

 phorus cfioerostomus and Siphodoma jonesi were once believed to be 

 peculiar to Bermuda, but only a year or so ago the U. 8. Fish Commis- 

 sion expedition to Porto Eico found both these species there. The 

 Bermuda representatives were in all probability derived from the West 

 Indian region, Ulaema lefroyi also is now known from many of the 

 West Indies, and the Florida Keys. 



The classic on the general Natural History of the Bermudas is Jones, 

 Wedderburn, and Hurdis ('59) ; while more recently Verrill (: 02) has 

 published a most valuable and interesting volume dealing with the 

 history, scenery, etc., of the island and on the faunistic changes due to 

 man. In (: 01) Verrill also published a paper dealing with the fauna ; 

 this contains a short article on the fishes. The birds and several 

 groups of invertebrates have been treated in a volume by Jones and 

 Goode ('84). An interesting popular account of the fish markets of 

 Bermuda was published by Goode ('76*') in "Forest and Stream," 

 Gllnther ('79) has listed the species of fishes taken by the naturalists 

 of H. M. S. Challenger near the islands. 



In the present paper the notes on distribution are obtained partly from 

 " The Fishes of North and Middle America," by Jordan and Everman, 

 which I have found very valuable in this connection, and partly from 

 specimens in the vast collections of the Museum of Comparative 

 Zoology.
