On Buteo solitarius. 



Dr. Sclater^ in his account of the birds collected in the 

 Sandwich Islands during the visit of the ' Challenger' to 

 Hilo Bay, published in the P. Z. S. for 1878, p. 346, and 

 subsequently in the 'Zoology of the Voyage of H.M.S. 

 Challenger/ pt. 8, p. 93, mentions, under the head of Buteo 

 solitarius, that "two specimens were obtained, but one of 

 them was subsequently lost." The specimen supposed to have 

 been lost has since come to light ; a ticket had been attached 

 to it (apparently through some inadvertent error) which 

 bears an inscription to the following effect : — " $ . Yedo Bay, 

 Japan. Eyes brown ; " and this led to its being misnamed 

 "Buteo japonicus." Both specimens are preserved in the 

 British Museum, and both are undoubtedly referable to 

 B. solitarius. 



The following are the principal measurements of this 

 second specimen, and they are very nearly identical with 

 those of the female already described and figured in the 

 ' Zoology of the Voyage of the Challenger,' viz. : — 



in. 



Wing 11-8 



Tarsus 2-8 



Middle toe 5. m 1-8 



Culmen, exclusive of cere Tl 



Speaking of the first specimen as no. 1, and of the second 

 as no. 2, I may state that the latter agrees with the former 

 in the scutellation of the tarsus and foot, in the form of the 

 bill, aud in the emargination of the inner webs of the four 

 first primaries; it also agrees in markings and coloration.
