subspecies mostly obtained in Colombia, and many of tliem 

 by Mr. Chapman himself. 



In some cases a review of all the subspecific forms of a 

 species are given, and this undoubtedly makes a paper of 

 this sort of much greater value to those who have to consult 

 it later. This is notably the case with the Sparrow-hawk, 

 Cerchneis sparverius, of which seven forms are recognised 

 from various parts of South America. 



Coale on the Trumpeter Swan. 



[The Present Status of the Trumpeter Swan (Olor buccinator) . By 

 Henry K. Coale. Auk, xxxii. 1915, pp. 82-92, pis. vii.-x.] 



The Trumpeter Swan, first made known to ornithologists 

 hy Dr. John Richardson " from the interior of the fur 

 countries ^' in 1831, seems to have become very rare of late 

 years; in fact, in the opinion of many members of the A.O.U. 

 who discussed the matter at a meeting held in New York 

 City in the fall of 1913, this magnificent bird is rapidly 

 Hearing extinction. 



Mr. Coale has in this paper reviewed the literature on the 

 subject, and has instituted enquiries among the various 

 museums and institutions in the United States and Canada, 

 as to the numbers of examples there preserved. He finds 

 that in the whole of North America there are preserved in 

 museums only sixteen specimens which have authentic data. 

 These were collected between the years 1856 and 1909. 



It looks as if the Trumpeter would very shortly share the 

 fate which has already overtaken the Passenger Pigeon, 

 unless some efforts are made to preserve it.
