the chimpanzee the head is thickly clothed with hair, the face 
is flesh-colored, and the ears are smaller. Both these animals 
(which are in the London Zoological Garden) are carnivorous, 
catching and eating sparrows and pigeons. It is stated that 
this is never done by the chimpanzee. Dr. Sclater provision- 
ally refers these animals to the Anthropopithecus calvus of Du 
Chaillu. 
Zoological News.— Cg^lenterata.— Dr. H. V. Wilson 
records {J. H. U. Circ, No. 70) that in Cereactis bahantensis 
the mouth occasionally grows together in the middle, leaving 
oval and anal openings at the ends. He also found a single 
larva of Manicina areolata, which exhibited the same pecu- 
liarity. In this connection reference is made to Sedgwick's 
celebrated paper on Metameric Segmentation. 
In the same place Prof J. P. McMurrich gives a list of the 
Actinaria of New Providence, enumerating fourteen species, of 
which Cereactis bahamensis, Bunodes tceniatns, Aulactinia stel- 
loides, and Gevimaria isolata are new. The fact is also re- 
corded that Aulactinia stelloides passes through an Edwardsia 
stage when eight nusenteries are present and the longitudinal 
muscles are arranged as in that genus. 
ENTOMOLOGY.' 
Observations on Ants, Bees, and Wasps.'— Sir John 
Lubbock has published the eleventh part of his observations. 
He is of opinion that, though there may be nests of Formica 
sajigidnea without slaves, an experiment which he has made 
seems to indicate that the slaves perform some important 
functions in the economy of the nest, though it is not yet de- 
termined what that function exactly is. 
With regard to Ant-guests, he points out that Dr. Wasman 
has confirmed his observations, in opposition to Lespes, that, 
while ants are deadly enemies to those of other nests, even 
of the same species, the domestic animals maybe transferred 
from one nest to another, and are not attacked. Attention 
IS next drawn to Professor Emery's observations on mimicry 
With regard to the color sense, Professor Graber has con- 
firmed Sir John's observations on Ants and Daphnias, by
