 Cocos Island. 



Range. East Indies, Polynesia, Hawaiian Islands; Revillagigedo, 

 Clipperton and Cocos islands. 



We have 10 specimens of this species from Cocos Island and one 

 from Clipperton Island. It is another East Indian species taken here-

136. XESURUS PUNCTATUS (Gill).

 (1899), 28 (Socorro Island). 



Range. Pacific coast of Mexico and the Revillagigedo Archi- 

 pelago. 



There appear to be but 3 species of this genus, all inhabiting the 

 eastern tropical Pacific. X. punctatus is a mainland form occur- 

 ring also at the Revillagigedo Archipelago, X. hopkinsi Gilbert & 

 Starks is known only from Panama, while X. laticlavius is exclusively 

 an island form known from the Revillagigedo, Clipperton, Cocos and

Prionurus laticlavius VALENCIENNES, Voyage de la Venus, 337, pi. 7, fig. 2,

 Xesurus clarionis GILBERT & STARKS, Proc. U. S. Nat. Mus. 1896. 445, pi.

 Xesurus laticlavius, JORDAN & EVERMANN, Fishes North and Mid. Amer., n, 



1695, 1898. 



Range. Revillagigedo, Cocos and Galapagos islands, Valen- 

 ciennes, in 1846, figured, and later described, the species Xesurus 

 (Prionurus) laticlavius from the Galapagos Archipelago. We have 

 numerous (37) specimens from Cocos and the Galapagos islands of a 

 species that is certainly the same as that figured by Valenciennes. 

 His figure, however, is very inaccurate, being of a depth much less 

 than that of most of our specimens, none of which also has the longi- 

 tudinal yellow band on the side shown in his figure. 



Gilbert and Starks, in 1896, described and figured the species 

 Xesurus clarionis from the Revillagigedo Archipelago. This species
