A second communication fi'ora ]\Ir. Sala'ix related to a 

 new species of Petrel. 



In. the collection of birds made by !Mr. Hawkins on the 

 Chatham Islands were two sjjecimens of an CEffrelata be- 

 longing to a species allied to (E. cooki, but wliich differed 

 in several marked characters. The skins were not quite 

 adult, but were marked male and female"; the birds were 

 shot on the south-east island on the 8th of jNIay, 1892. 

 !Mr. Salvin proposed to describe the species as follows : —

CE. cooki affinis, sed minor ; rostro breviore et magis robusto : 

 supra pallidior, tectricibus alarum mediis cinerascentibus 

 albo limbatis. rectricibus lateralibus magis cinereis ; axil- 

 laribus et tectricibus alarum secundariis subtns nigris : 

 rostro nigro, pedilius carneis, digitis et palamis plerum- 

 que nigris ad basin carneis. Long, tot a circa 12"0 poll., 

 alee 8*3. caudte rectr. med. 3'8, rectr. lat. 3"2, rostri a 

 rictu 1''6, tarsi r2, dig. med. cum ungue To.

 last Meeting of the Club, as well as examples of its 

 nearest allies. 



Mr, Haktert also exhibited the skin of a Goose, supposed 

 by him to be a hybrid between Berrucla hrenta and Anser 

 albifrons. 



Mr. Henry Seebohm gave a short explanation of a theory 

 propounded by Dr. Nicholski, of St. Petersburg, to account 

 for the variation in the shape of birds' eggs. 



]\Tr, W. Pl. Ogilvie-Grant made some remarks on the 

 classification of the Game Birds and on the changes of the
