the volador of Joidaii. The species with the second ray of the pectoral 

 divided is thus left without a name, and we suggest that of Uxocvctus 

 vinciguerrcu in honor of our excellent friend, the ichthyologist of the 

 Museo Civico at Genoa, who was the first to show the correct applica- 

 tion of the name rondeleti. 



Of this species we have examined three examples. One, which may 

 be regarded as the type of Exocwtus vincigiierrce (No. 21870, U. S. Nat. 

 Mus.), is from the open sea south of Newfoundland. Two others are in 

 the museum of the academy. One of these is 6^ inches long, from the 

 Gulf of Mexico (Dr. J. Carson), and the other, Scinches long, from St. 

 Martin's (Dr. E. Y. Eijgersma). 



The young of this species, like that of jE7. exiliens, has the paired fins 

 marbled. The first rays of the pectoral are also separated by a broad 

 membrane in the young of this, as of other species.

The Exoccetii.s volitans of Linnaeus is based on the Exocoetus of Artedi. 

 The locality of the specimen described in detail by this author is not 

 stated. There is no evidence that it came from the Mediterranean. It 

 is evident from the numbers of the fin-rays that Artedi's example did 

 not? belong to the species called volitans by Cuv. & Val. As the rays 

 «f the dorsal and anal are each stated to be eleven, the name volitans 

 must be reserved for one of the species with the anal fin long. The 

 ventral fins are said to be white, which fact excludes from considera-
