A CONTRIBUTION TO THE ICHTHYOLOGY OF 



BERMUDA. 



BY JOHN TREADWELL NICHOLS. 



The American Museum of Natural History has recently 

 received a collection of Bermuda fishes taken personally by 

 Mr. Louis L. Mowbray over a period of several years. Mr. 

 Mowbray is so thoroughly familiar with the piscifauna of that 

 locality that he is especially well qualified to judge what ma- 

 terial from there will prove of interest; and it follows that this 

 collection supplements, to a considerable extent, what is known 

 of Bermuda fishes. It contains seven species which appear to 

 be undescribed, as follows : 



Family Muraenidae. 

 Gymnothorax brunneus, sp. nov. 



Close to Gymnothorax (Lycodontis) funebris, but with different denti- 

 tion, less deep, dorsal origin further back, eye apparently smaller in 

 specimens of same length. The type, our only specimen, No. 7309, 

 American Museum of Natural History, was collected at Bermuda by Mr. 

 Louis L. Mowbray. It is 344 mm. in total length. Head 2.8 in trunk, 

 tail 0.7, depth 6.9. Gape 2.1 in head, snout 5.5. Eye 1.8 in snout, equal 

 to interorbital. 



Jaws curved, not quite closing. Long, depressible, simple canines in 

 jaws, and two or three (the longest) in a single row on vomer. An outer 

 row of smaller sharp, more or less unequal, retrorse teeth in jaws. Dor- 

 sal beginning over front of gill opening. Fins rather low. 



Color uniform dark chestnut brown, including fins which are unmarked. 

 Back and dorsal especially, of this specimen, thickly dotted with small 

 pale encrustations.
