Since Ave last mentioned this important book (see above, 

 p. 199) another part lias reached us. It continues the 

 account o£ the Order A.ccipitres, and contains the species of 

 the subfamilies Accipitrmce and Buteonina', with the greater 

 ])ortion of the Aquiliiue. As in the former Parts the details 

 on all the species are copious, and the illustrations of the 

 nests excellent. 



79. Oherhulser on the Forms q/Collocalia fucipliaga. 



[A Revision of the Forms of the Edible-nest Swiftlet, CollvcaUa fuci- 

 ohiKja. By Harry C. Oberholser. Pr. U.S. Nat. Mus. vol. xlii. p. 11.]

 divisible into two sul)families, the Merophue and the Nycti-
