144 THE SHORE FISHES. 
One specimen, 53 inches long without tag or locality. 
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 lines running downward from in front and from behind the 
eye. The color of the young is well described by Snodgrass and Heller. 
TEUTHIDIDAE. e 
- ‘Teuthis triostegus (Livé). 
Chaetodon triostegus LINNE, Syst. Nat. ed. 10, 1758, p. 274. 
Eight specimens each about 14 inches long from Manga Reva, February 3, 4 
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 7. 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. 
Bull. U.S. Fish. Comm., 1903, 22, p. 477. 
Two examples, Nos. 3181 and 3164, M. C. Z. 29677, 8¢ and 6z 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.
