XVIII. — On an Owl from South-east New Guinea, allied to 

 Ninox terricolor, Ramsay, but apparently distinct and un- 

 described. By J, H, Gurnby. 



The Norwich Museum has recently obtained, through Mr. 

 Whitely of Woolwich, three specimens of an Owl of the 

 genus Ninox, collected by Mr, Goldie in South-eastern New 

 Guinea, which much resembles the species described by Mr. 

 E. P. Ramsay in the ' Proceedings of the Linnean Society of 

 New South Wales ,^ vol, iv, p. 466, under the name Oi Ninox 

 terricolor, but is of considerably larger dimensions thau 

 those given by Mr, Ramsay for that species.
