birds. In one of these he rejects the generic name Banner- 

 mania recently proposed by Mathews and Iredale for a 

 Pacific Petrel, as well as Cymochorea Coues, which was 

 revived by the same authors. He also discusses and 

 criticises the changes proposed by Lord Rothschild and 

 by Mathews & Iredale in the matter of the names of the 

 Frigate-birds and Petrels. 



With regard to the Waxwiiig (^Ampelis or Bombycilla gar- 

 rulus), which has been hitherto generally treated as a widely 

 ranging but unvarying species from western Europe through 

 Asiato eastern North America, Oberholser believes that he can 

 distinguish three races — a darker European {B. g. garrulus), 

 a somewhat paler central Asian {B.g. centralasice Poljakov), 

 and a still paler and more greyish American (B. g. palli- 

 diceps Reichw.). He also controverts the decision of the 

 Committee of the B. O. U. in regard to the usage of the 

 generic name Ampelis for the Waxwing, and believes that 

 he is correct in the use of Bombycilla. A further examina- 

 tion of this question is desirable so that a definite and final 

 conclusion can be reached acceptable to all ornithologists. 



During his trip to Labrador in the summer of 1915, 

 Dr. C. W. Townsend obtained a pair of Chickadees or 

 Tits which he found to be a hitherto undescribed race 

 and named Penthestes hudsonicus nigricans. In the winter 

 of 1916-17 a great southward migration of Chickadees took 

 place into the region about Boston, and Dr. Townsend had 

 the satisfaction of recognizing his Labrador form among the 

 migrating birds. In a short paper relating this he comments 

 as follows : — " It is not often that the discoverer of a new 

 race in a distant land is so fortunate as to have that race 

 return his visit in his own home.'' 



A paper on rather novel lines is that of Mr. H. Mousley, 

 who has made a number of detailed observations on second 

 nestings and laying. He finds that when the first nest and 

 eggs are taken, about 70 per cent, of the birds make a second 

 nest and about 30 per cent, two subsequent nests ; that the 

 new nest is made and the second clutch laid, on an average
