144 THE SHORE FISHES. 



One specimen, 5f inches long without tag or locaUty. 



In these specimens, there are numerous small round, grayish spots on the 

 nape in front of dorsal ; in other respects they agree with current descriptions. 

 In some of our young examples there are coarse reticulations of blue lines on the 

 cheek between the hues running downward from in front and from behind the 

 eye. The color of the young is well described by Snodgrass and Heller. 



TEUTHIDIDAE. 



Teuthis triostegus (Linne). 

 Chaclodon triostegus Linn£, Syst. Nat. ed. 10, 17.58, p. 274. 



Eight specimens each about 1? inches long from Manga Reva, February 3, 

 '05. M. C. Z. 29414 (3 specimens). 



Our specimens agree with Street's account (Bull. 7, U. S. Nat. Mus., p. 67) 

 of Acanthurus triostegus in the color markings with the exception of those on the 

 tail. They also agree with specimens from Samoa in Jordan and Seale's collec- 

 tion labeled T. triostegus. All of our specimens have at least traces of a bar 

 across caudal peduncle and one across base of caudal fin. In most of them the 

 former bar is more distinct; in one instance the bar across base of caudal is 

 more distinct; in one instance the bar extends across caudal peduncle on one 

 side of the specimen and on the other side only partly so. 



Teuthis umbra Jenkins. 

 BuU. U. S. Fish. Coram., 1903, 22, p. 477. 



Two examples, Nos. 3181 and 3164, M. C. Z. 29677, 8i and 6i inches long, 

 from Cook Bay, Easter Island. 



Comparing these specimens with a specimen from Hawaii, we find them 

 identical in color, except that the white on the base of the caudal is not so evident, 

 but it is very faint in the Hawaiian specimen. The profile between the snout 

 and front of eyes is a little more concave in our specimen ; the caudal fins are 

 similar in emargination. 



For purposes of comparison we give the following measurements of our 

 specimens and of the Hawaiian specimen. 



No. 3181 has, head 3.77 in length without caudal; depth 1.70; eye 4.09 in 

 head; snout 1.19; interorbital 2.81 ; dorsal IX, 25; anal III, 22. 



No. 3164 has, head 3.68 in length; depth 1.66; eye 3.77 in head; snout 

 1,30; interorbital 2.83; dorsal IX, 25; anal III, 23,
