55. Bulletin of the Nuttall Ornithological Club. 



[Rullotin of the Nuttall Ornitholonfical Club : a Quarterly Journal of 

 Ornithology. Vol. vii. no. 2, April 1882. 8vo. Cambridge, Miiss.] 



Among the varied contents of the present number the most 

 interesting are perhaps the first portion of Mr. Brewster's 

 memoir of the birds collected in Arizona by Mr. F. Stephens, 

 and Mr. Lucas's notes on the os prominens. In Mr. Stephens's 

 series of 650 skins, '' embracing the results of six months, 

 uninterrupted work/' were examples of many rare Western 

 species, such as Harporhynchus bendirei, H. crissalis, Auri- 

 •parus flaviceps, and Helminthophaga lucice. 



56. Collett on new Norwegian Birds. 



[(hrocincla varia (Pall.) og JEgialitis alexandrina (Linn.), nye for 

 Norges Fauna. Af Robert Collett. Vid.-Selsk. Forh. Christiania, 1881, 

 no. 10.] 



Mr. Collett records the occurrence of an example of Oreo- 

 cincla varia near Stavanger, in October 1879, and of j^gia- 

 litis alexandrina (i. e. jE. cantiana) near Jaderens Rev, in 

 June 1881. The latter was killed by the writer himself out 

 of a flock of five birds, all apparently of the same species. 

 Mr. Collett advocates the usage of Linnseus's term alexan- 

 drinus for what is commonly termed the Kentish Plover. 

 Both species are new to the avifauna of Norway. 



57. Collett on the Ear -formation of the North-European 

 Owls. 



[Craniets og Oreaabningernes Bygning hos de nordeuropfeiske Arter af 

 Familien Strigidse af Robert Collett. Vid.-Selsk. Forh. Christiania, 1881. 

 no. 23.] 



This very useful and instructive paper contains an account 

 of the formation of the organs of hearing in the ten North- 

 European Owls. These are all Buboninse, Strix being want- 

 ing in Scandinavia^ and fall into .six groups, in two of which 

 the cranium is asymmetrical.
