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

 Ninox terricolor, Ramsay, but apparently distinct and un- 

 described. By J. H. GURNEY. 



THE Norwich Museum has recently obtained, through Mr. 

 Whitely of Woolwich, three specimens of ari 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 of Ninox 

 ierricolor, but is of considerably larger dimensions thau 

 those given by Mr. Ramsay for that species.
