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 Jourmal, 

 that gentleman describes five new species of the family of 

 Fespertilionidae respectively belonging to the genera Pteropus, 

 Rhinolophus, A^ycteris, and the Fespertilio 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 Mangusta of Olivier ; a new species to each of the 

 genera iVfyoxus, iSciurus, iepus, and Bathyergus, among the 

 Glires ; and one to Phocae^na among the Cetacea. In addi- 

 tion to these species belonging to well 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 

 iSoreXjhe describes under the generic title of Macroscelides * ; 

 the second, which he conjectures to follow immediately after 

 ikfus, under that of Dendromus. 



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 Cervus, 

 C. leucurus, discovered by him in the Rocky Mountains. He 

 has also given, in the Zoological Journal, a more accurate de- 

 scription than we have hitherto possessed of that interesting 

 animal mentioned so frequently by the American writers, the 

 OVis 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 «S'6rex ^raneus 

 maximus capensis 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 Rodentia, the Marsupialia, 

 and the Insectivora. These analogies may be exhibited in a tabular view, 

 as follows.: — 



Dasyurus. *S'6rex. 



Phascolomys. Talpa. 



Chironectes. ikfygale. 



Petaurus. Tupdia. 



Kdngarus. Macroscelides.
