TWENTIETH ANNUAL REPORT lat: 
The large California sea lion (Zalophus californianus) con- 
tinues in good health. It has been in the Aquarium eight years. 
The young sea lions deposited by Messrs. Travilla Brothers re- 
main in good condition. 
Three new species of tropical fishes from Key West, Florida, 
have been discovered in the living collections of the Aquarium 
during the past eighteen months. One of these, a large serranid 
(Dermatolepis marmoratus) Osburn and Mowbray, was de- 
scribed in Zoologica, February 25, 1915. Another, a grunt 
(Haemulon crysopterum) Mowbray, was described in the Bul- 
letin of the Zoological Society for November, 1915. The third, 
an angel fish (Angelichthys townsendi), Nichols and Mowbray, 
was described in the Bulletin, American Museum of Natural 
History, October 8, 1914. 
A penguin (Spheniscus humboldti) from the coast of Chili 
was presented early in July by Mr. W. O. Swatridge of Brook- 
lyn. This aquatic bird was a decided attraction through the 
summer and autumn. It was kept in the sturgeon pool during 
the daytime, where it had a small raft on which to rest. At 
night it occupied an open pen on the gravel roof. It fed entirely 
on fresh fish cut in small slices, refusing all other kinds of food. 
It became very tame, following its keepers anywhere about 
the building when called. The bird appeared to be thriving and 
enjoying life but it died suddenly in December. 
A very large lobster taken by the fishing schooner Stranger 
from a depth of 100 fathoms on the tile fish banks was received 
in October. 
It measured thirty-eight and one-half inches from end of 
large biting claw to tip of tail, and weighed fifteen and three- 
quarter pounds, the crushing claw having been lost and replaced 
by a new one only five inches long. Like other specimens from 
deep water it did not live long in captivity. This lobster was 
presented to the Brooklyn Museum. 
Through the courtesy of the United States Bureau of Fish- 
eries the fish hatching exhibit at the Aquarium was kept in 
operation during the greater part of the year; fish eggs of 
several species having been furnished from government hatch- 
eries. The young fry were delivered to the State of New York 
as usual. *
