196 MR. FRASER ON THE MOLLUSKS OF FORMOSA. [Feb. 14, 
A letter was read, addressed to the Secretary by Prof. J. J. Bian- 
coni, of Bologna, stating that, in the course of researches upon the 
osteology of the extinct genus Apyornis, he had come to the con- 
clusion that that form belonged to the Vulturide, and not to the 
Struthious birds. 
Mr. Alfred Newton exhibited a specimen of Porzana carolina, 
lent to him by Mr. H. S. Eyre, who had shot it, in October last, on 
the Kennet, near Newbury. Mr. Newton remarked that though 
the species of the family Rallide were, as compared with other birds, ° 
very short-winged, yet experience showed that in their flight they 
were gifted with considerable powers of endurance. For instance, 
the common Corn-Crake (Crex pratensis) had been known to occur 
once in the Bermudas, and several times on the eastern coast of the 
United States, as well as once in Greenland, where the species now 
exhibited had also been observed. In the British Museum, too, 
there was an example of T'ribonyx ventralis, which was obtained by 
the Antarctic Expedition, when at sea, between Tasmania and Auck- 
land Island. 
Mr. Fraser read the following list of species of Mollusks re- 
cently collected by Mr. R. Swinhoe in Formosa, stating that the 
list had been furnished to him by Mr. Cuming, C.M.Z.S., and was 
that of the collection spoken of by Mr. Swinhoe in Proe. Zool. Soc.
