A second genus of this tribe of birds was then characterized as 
Genus OcypHaps. 
Gen. char.—Caput crista occipitali elongata. Ale pauld breves, re- 
mige tertid gradatim ad apicem coarctata. Cauda mediocritér 
elongata, et rotundata. Tarsi et digitus intermedius eadem lon- 
gitudine. Digitus internus externo brevior. 
Type, Columba Lophotes, ‘Temm. 
A second example of the genus Pedionomus was described as 
Pepronomus microurus. Ped. a P. Torquato diversus, staturd 
minore, collo haud torque circumdato, caudd feré carente.

Differs from P. torqguatus in its smaller size, in the absence of the 
collar, and in the almost total absence of tail. 
Mr. Gould also brought before the notice of the Meeting a new 
species of Megapodius, from the north coast of Australia, which he 
characterized as M. Tumulus, and read a very interesting account of 
its habits, which tends to confirm the opinion he had previously ex- 
pressed, that Megapodius Talegalla and Leipoa form part of one great 
family of birds, whose range will be found to extend from the Phi- 
lippines to Australia.
