and 2, January and April 1902.] 
Mr. A. C. Bent begins the year with a continuation of 
his illustrated paper on the nesting-habits of the Anatidse 
in Northern Dakota, which is concluded in the April 
number. Mr. James Haynes Hill contributes a short article 
on Loxia leucoptera in captivity ; while the title of Mr. J. 
W. DanieFs paper on the summer birds of the Great 
Dismal Swamp will revive recollections of anti-slavery 
agitation in readers of mature age. Mr. W. H. Kobbe 
investigates the question of the species or races of Herring- 
GuUsj and/ comes to the conclusion that there is no specific 
distinction between Larus argent atus and L. vegceoi Palmen, 
but that L. cachinnans is quite recognisable. We are glad 
to see that he has made good use of the Cat. Birds Brit. 
Mus. vol. XXV., although he has not arrived at quite the same 
conclusions as the author of the section Gavise. Mr. H. B. 
Bigelow's list of the birds observed on the north-eastern 
coast of Labrador is a useful supplement to Mr. L. M. 
Turner's birds of Ungava. The Beport of the Committee 
on the Protection of North- American Birds is of great 
interest, especially Mr. Butcher's portion relating to the 
Gulls and Terns. We may pass over some American papers 
which will be duly noted by the recorder of ' Aves ^ in the 
' Zoological Record ' ; but occurrences of Mareca penelope 
in North Carolina and Long Island, as well as of Nettion 
crecca in the latter, deserve mention on this side of the 
water. — H. S.
