described. The geographical, hydrographical, and geological distribution of 
the species enumerated were fully given. 
Mr. F.C. Selous read a paper on the South African Rhinoceroses, based 
upon specimens collected and observations made during nine years’ hunting 
in Southern and South-central Africa. Mr. Selous had come to the .con- 
clusion that in these countries only two well-marked species of Rhinoceros 
existed, namely, the square-mouthed [Rhinoceros simus, and the prehensile- 
lipped R. bicornis. 
June 21, 1881.—Prof. W. H. Frowrr, LL.D., F.R.S., President, in 
the chair. 
The Secretary read a report on the additions that had been made to the 
Society's Menagerie during the month of May, 1881, amongst which special 
attention was called to an African Wild Ass (Hquus teniopus) from Upper 
Nubia, and a White-winged Duck (Anas specularis) from Antarctic America, 
both new to the collection. 
Mr. R. Bowdler Sharpe exhibited a specimen of Podilymbus podiceps, 
stated to have been killed at Radipole, near Weymouth, in the winter of 
1880-1.% 
Mr. W. A. Forbes read a paper on the Petrel called Thalassidroma 
nereis, by Gould. This, he showed, was not a true Procellaria, but must 
form the type of a new genus, proposed to be called Garrodia, most closely 
allied to Oceanites, F'regetta, and Pelagodroma, and constituting with them 
a distinct family of ‘ T'wbinares,” proposed to be called ‘* Oceanitide.” 
Mr. W. A. Forbes read a paper on the conformation of the thoracic 
extremity of the trachea in the “ Ratite” birds, calling particular attention 
to the existence of a highly-developed syrinx in the genus Rhea, in which 
respect it differed from all the other genera comprised in that group. 
A communication was read from Mr. George F. Bennett containing an 
account of the habits of the Hchidna hystrix of Australia, as observed by 
him during three years’ exploration of their native haunts. 
Mr. G. A. Boulenger read a paper on the Lizards of the genera Lacerta 
and Acanthodactylus, prepared after a study of the specimens of these 
genera in the collection of the British Museum. 
Mr. F. C. Selous read a paper in which he gave an account of the 
Antelopes that had come under his observation during a residence of eight 
years in central South Africa. The author exhibited a series of skins of 
the Bush-buck (T’ragelaphus sylvaticus), and pointed out their variations in 
different localities, also specimens of the Poku (Cobus Vardoni) and Speke's 
Antelope (Tragelaphus Spekii).
