below the chin. Females and immature males are sometimes 

 difficult to distinguish, but in E. personata the underparts 

 are generally a much brighter yellow. The latter species 

 has not been found in China. 



STRIX RUFESCENS. 



Three examples from Nagasaki of this variety of S. ura- 

 lensis are so dark and rufous as to appear specifically distinct. 

 The lighter bars across the first primary and the two centre 

 tail-feathers are almost obsolete. This form probably re- 

 places S. uralensis in the main and south islands of Japan. 



BUBO BLAKISTONI, Seebohm, anteh, p. 42. (Plate VI.) 

 An immature example of an Owl obtained in the neigh- 

 bourhood of Shanghai by Mons. Heude is in the museum 

 of the Jardin des Plantes at Paris. It was determined 

 by Mr. Sharpe (Ibis, 1875, p. 255) as Bubo coromandus, and 

 adult examples since received from the valley of the Yang- 

 tse-kiang have confirmed his decision. It had been de- 

 scribed as Bubo sinensis (Heude, Ann. Sc. Nat. Paris, ser. 5, 

 xx. article 2), a name apparently taken from Daudin (Traite 

 d'Orn. ii. p. 209), who appears to have founded it upon an 

 Eagle-Owl from China, which Manduyt (Encycl. Meth. Orn. 

 ii. p. 73) says differs from our bird, but does not state in 

 what respect. This bird is perfectly distinct from the Japan 

 Eagle-Owl, Bubo blaldstoni, of which a figure (Plate VI.) is 

 now given. 



PANDION HALIAETUS. 



Two examples of this bird, one a female from Hakodadi 

 (No. 2061) obtained in October, and the other obtained by 

 Mr. Ringer at Nagasaki, agree in size with the typical 

 form, and measure 19 J and 19 inches in length of wing. 



AQUILA PELAGICA. 



A fine example, not quite adult, of this magnificent Eagle 

 from the eastern part of Yezo shows the enormous deve- 

 lopment of bill in this species, the height of the bill being 

 greater than that of the skull. It also confirms the inter- 

 esting fact, pointed out by Baird, Brewer, and Ridgway, that 

 this species has fourteen tail-feathers.
