A new Laniarius, L. /agdeni, from Ashantee, has been described 
by Mr. R. B. Sharpe. 
Mammals.—An examination of the uterus of the four-horned 
antelope, made by W. F. R. Welden, showed that it is divided into 
two compartments by a partition extending one inch into a passage 
internal to the os uterus. The Fallopian tubes are very small. 
The placenta is exactly intermediate between the completely diffuse 
one of Moschus, and the complexly cotyledonary apparatus of the 
sheep, for example, on the other. Each foetus has twenty-two to 
thirty cotyledons, 
he lesser koodoo (Strepsiceros imberbis) differs from S. kudu, 
not only in its smaller size, but in the absence of the fringe of 
long hair down the neck in front, and in the much more com- 
pressed spiral of the curvature of the horns. Mr. Holmwood, 
British Consul at Zanzibar, states that it occurs on the Juba river, 
exactly under the equator, in groups of three or four. A stuffed 
example from Somali land is in the British Museum. 
EMBRYOLOGY." 
ON THE AVAILABILITY OF EMBRYOLOGICAL CHARACTERS IN THE 
CLASSIFICATION OF THE CHORDATA.—The development of a me- 
dian axial cord, differing essentially from cartilage, and which 
seems to arise from a strand of cells constricted off longitudinally 
justified by facts. Lankester insists for this reason that the term 
Vertebrata be abandoned, and that the word Chordata be substi- 
tuted for the name of the phylum, so as to express a fundamental 
truth in scientific taxonomy. 
It has been insisted that embryological data are not available 
for the purpose of discriminating classes, subclasses, etc., and,
