604: Zoological Proceedings of Societies, 



scribed under the generic name oi Kinyxis^ to which two species 

 were already referrible. A discussion subsequently ensued on the 

 subject of the circular succession of affinities and on analogies, in 

 which Mr. Vigors and Dr. Horsfield took part. 



March 27. — Mr. Yarrell exhibited a specimen of the Anas 

 rufina^ Pallas, from the neighbourhood of Yarmouth. The occur- 

 rence of this second British specimen confirms the opinion ad- 

 vanced by Mr. Vigors at the meeting on January 29, 1826, that 

 the species is entitled like other occasional visitors of these islands 

 to a place in our Fauna, Mr. Yarrell also exhibited a specimen 

 of a hybrid Bird between the Pheasant and the dark Dorking 

 variety of the common Fowl. 



Mr. Vigors entered into some general observations on the geo-, 

 graphical distribution of Birds, especially with reference to the 

 forms met with in New Holland. He proposed to continue the 

 subject at future meetings. 



Ai)ril 10. — A Paper On the Orang-Otang of Borneo : by John 

 Harwood, M.D., F.L.S., &c. was read. Some observations on the 

 same subject were made by Mr. Brookes, in the course of which 

 he explained the principal differences between the skeletons of the 

 Chimpanzee and the Simia Satyrus^ L. 



At the request of the Chairman, Mr. Gray adverted to the cha- 

 racter assigned by M. G. Cuvier to the genus Basiliscus^ Laur. 

 He remarked that the description of the teeth appeared to have 

 been taken from the Lacerta Jmboinensis, L. On examining the 

 specimens preserved in the British Museum, the teeth of this 

 species were found to agree with those of the Iguanidce ; the 

 teeth of the Basiliscus Americanusy Laur., on the contrary, corres- 

 pond precisely with those of the Agamidce, The two species 

 were consequently referrible to distinct genera. To designate the 

 former, he proposed to retain the generic name of BasiliscuSy 

 while to the latter the name of Lophura would be given in a paper 

 on the above-mentioned families, which he was preparing to lay 

 before the Club. 



Mr. Westwood exhibited living specimens of the Aphanisiicus 

 emarginatus^ Lat., a rare British Insect, and of the larva of a 

 species of Cicindela^ L,, both recently taken by him, the latter
