BULLETIN OF THE UNITED STATES FISH COMMISSION. 
Fish Commission. A representative collection has been presented to the British 
Museum and one retained by the museum of De Pauw University. 
The following list gives full descriptions of all the new genera and species not 
given in my previous papers or that recently published by Jordan & Evermann.® 
Since, in the forthcoming report by these authors a complete list of all the species 
known to be recorded in the Hawaiian Islands, with a full discussion of their syn- 
onymy, is to be given, I have included only those species of which I have examples 
in my collections. The synonymy given is limited to that which will give the 
student into whose hands this paper may fall a ready reference to the most impor- 
tant works treating of the species here listed, or to that which seems necessary to 
discuss doubtful identifications. In the synonymy, localities without parentheses 
are type localities; those with parentheses are localities from which the species was 
recorded by the author cited. 
Illustrations from drawings by Mr. W. S. Atkinson are given of all new species. 
Family I. CARCHARIIDA. 
1. Carcharias melanopterus Quoy & Gaimard. 
Very common at Honolulu. Three were taken by me ifi 1889. It has been known from the 
Indian Ocean and Archipelago, but this is its first record from the Hawaiian Islands. 
Color in life, upper part of body a very light olive, covered with pretty thickly set fine points of 
brown; belly nearly white; tips of all the fins inky black; whole margin of caudal black; pupil and 
iris very light, almost white.

Two specimens (Nos. 245 and 546), 29 and 28 inches long, were obtained. Six examples (one of 
them a foetus) were obtained at Honolulu by Jordan & Evermann in 1901. 
Color in alcohol, dark gray, lighter on ventral aspect; tip of pectoral and tip of lower lobe of caudal 
darker; tip of dorsal and upper lobe of caudal only slightly darker than rest of fin.

Snout 4.5 to base of tail; eye about 3.67 in interorbital space; interorbital space broader than 
length of snout; width of mouth 2 in interorbital; internasal space 2 in interorbital. Body somewhat 
pentagonal in form; length of disk 1.42 in width, the line of greatest width passing about the length 
of the spiracles behind them; anterior margins nearly straight ; tip of snout not projecting, very obtuse;
