Color in life (field No. 03535), upper parts of body and head light brown, lower parts white; fins 
tipped with black; upper and lower borders of caudal also black. Another example, 4.5 feet long and 
similarly marked, was seen in the market of Honolulu. 
Color in alcohol, pale brown above, the lower portions white; a brown longitudinal band along 
side from below front of first dorsal backward over base of ventral; upper surface of pectorals and 
ventrals brown like the back; upper extremity of dorsal, broadly and abruptly blotched with black; 
margins of caudal narrowly black, the greater part or outer half of the lower lobe black; outer 
portion of anal black; lower tip of pectoral blackish, the upper edge or marginal portion also blackish 
or dusky, and the lower tip of ventrals broadly blackish. Description from a male 31 inches long 
taken at Honolulu. 
This shark is a common form throughout Polynesia. We have a number of examples from 
Honolulu, three of which were collected in 1889 by Dr. Jenkins. The species was also found at 
Samoa by Jordan and Kellogg. It. may be known at once by the inky black tips to its fins.

This description from an example 27.5 inches long, field No. 03747, taken at Honolulu. Type, 
No. 50612, U. S. Nat. Mus. We have 4 other examples also from Honolulu, one a foetus, besides 
2 from the same locality collected by Dr. Jenkins in 1889. Specimens were also secured by the 
Albatross in 1902 at Honolulu and at Hanalei Bay, Kauai.
