204 Address delivered at the sixth and last 
to the Fauna of South Africa, by Dr. Andrew Smith, a zealous 
corresponding member of the Zoological Society. In a paper 
published in the sixteenth number of the Zoological Journal, 
that gentleman describes five new species of the family oF 
Vespertilionidze respectively belonging to the genera Ptéropus, 
Rhindlophus, N¥¢cteris, and the Vespertilio of modern authors. 
He has also added a new species to the interesting form of 
Chrysochloris, of which only one had hitherto been known; 
two to the Mangista of Olivier ; a new species to each of ae 
genera Myoxus, Scitrus, Lepus, and Bathyér gus, among the 
Glir es; and one to Phocee na among the Cetacea. In addi- 
tion to these species belonging to w ell known groups, he has 
characterised two new animals, which he looks upon as exhi- 
biting such modifications of form as to demand separate places 
in our systems. ‘The first of these, which is nearly allied to 
Sorex, he describes under the generic title of Macroscélides * 
the second, which he conjectures to follow immediately after 
Mas, under that of Déndromus. 
To Mr. Douglas, whose social intercourse with us for the 
last few months has added so much interest to our meetings, 
and who has just left us, under the most favourable auspices, 
to retrace his steps over the western part of North America, 
we are indebted for the description of a new species of Cérvus, 
C. leucurus, discovered by him in the Rocky Mountains. He 
has also given, in the Yoological Journal, a more accurate de- 
scription “thari we have hitherto possessed of that interesting 
animal mentioned so frequently by the American writers, the 
O'vis montana of the same country. It were much to be 
wished that the example set by this enterprising naturalist 
would be more generally followed by scientific travellers, of 
giving their own descriptions of the animals they discover. In 
* M. Isidore Geoffroy St. Hilaire has since described this interesting 
genus with more detail in a paper in the Annales des Sciences Naturelles for 
October last. Specimens recently obtained from the Cape of Good Hope 
have enabled that promising naturalist to detect in it the Sorex Araneus 
maximus capénsis of Petiver, the figure of which had previously been 
regarded by modern writers as a mere caricature, so little did it resemble 
any animal with which they were acquainted. M. Isidore Geoffroy justly 
regards the acquisition of this new form among the Insectivora as of con- 
siderable importance, inasmuch as it furnishes the first example discovered 
of the fifth type in this group, and enables the zoologist to complete the 
exposition of the analogies existing between the Rodéntia, the Mar supialia, 
and the Insectivora. These analogies may be exhibited in a tabular view, 
as follows : — 
Marcheurs, Rat. Dasytirus. Sorex. 
Fouisseurs. Pore-épic. Phascélomys. Talpa. 
Nageurs. Castor. Chironéctes. Myzale. 
Grimpeurs. Ecureuil. Petairus. Tupaia. 
Sauteurs. Gerboise. Kangarus. Macroscélides.
