CONTRTIÎUTTONS TO THE ORNIS OF RAOUALIX. 57 



able fact in view of tlio facts tliat tlu; liazel-i^ronse is a very 

 stationary bird and lluis must have been isolated in Saglialin for 

 considerable ages, and that in other parts of the Palcearctic region 

 the species has developed into two different races. 



According to Nikolski the hazel-grouse is a very common bird 

 in Saghalin, witli which Professor Ijima's observation is in accord. 



89. Falco meniflits Gerini. 



Chipesani: 1$, Oct. 1. 



This species is not recorded in Nikolski's work. 



90. Accipiter nisun (Linné). 



Mou til of Susuya River : Id^, May 18. 

 Chipesani: 1?, Oct. 18. 



Nikolski did not observe any sparrow-hawk in Saghalin. 



The male specimen in this collection has no white neck 

 spot, but otherwise agrees with dark Swedish specimens of a 

 similar age. It seems most probable that the sparrows-hawk 

 breeds in Saghalin, and perhaps it may be proved in tJio future 

 that it represents a separate race, should the white neck spot 

 be always absent in the males at least. 



91. JPandion haliaëtus (Linné). 

 Chipesani : 1 Ç , Sept. o. 



Nikolski has also recorded the ilsh-hawk from Saghalin, 

 but has said that it is not numerous there.
