as of Daudin. The species of Circus and Leitcospiza are 

 carefully disentangled, the Grey and the White Goshawk 

 being referred to the latter genus, and considered distinct 

 species rather than colour variations, though they some- 

 times interbreeJ. Similarly many difficulties are cleared 

 up with regard to Astur appruximans, now shown to be 

 correctly named Urospiza fasciata. A new subgenus, Para- 

 spizias, is proposed for Accipiter cirrhocephalus. Hiera'etus 

 is used as the generic name for Nisaetus morphnoides, which 

 is considered to be merely a subspecies of the Palsearctic 

 H. pennatus, and Cuncuma is used for Haliaetus leucugaster. 

 Butastur teesa is given as doubtfully Australian. Ictiniastur 

 is proposed as a new subgenus for Milvus sphenurus of 

 Vieillot. 



The new subspecies in this Part are Circus assimilis 

 quirindus from Celebes, &c., and Accipiter cirrhocephalus 

 qiKSsitandus from northern Australia, while Leucospiza novee- 

 hollandice alboides is suppressed. 



Many of the Watling drawings come to be considered iu

Miller on new Generic Types. 



[Three new Genera of Birds. By W. De Witt Miller. Bull. Amer. 

 Mus. N. H. New York, xxxiv. 1915, pp. 515-520.] 



The new genus Slringonux is proposed for Bubo blakistuni 

 Seebohin as a type, and for its ally B. doerriesi, irom 

 Japan and from eastern Siberia respectively. Rlr. Miller 

 points out that these Owls are really most nearly related to 

 the Fish Owls, Ketupa, but quite distinct from these as well 

 as from Bubo. 



For the Neotropical Goatsuckers Hydropsalis lyra (Bp.) and 

 H. segmentata (Cass.), the new genus Uropsalis is pi'oposed, 

 the first-named species being the type. In the graduation 

 of the tail and the form of the wing these species are 

 markedly distinct from H. creagra, the type and only other 

 species of the genus Hydropsalis. A third genus, Chryserpes^ 

 is proposed for the peculiar Haitian Woodpecker, Chloro- 

 nerpes striatus (Miill.) of Shar])c's * llaud-list.^
