06s. On comparing adults of R. leucopygus with R. sociabilis in 

 the Leiden Museum, I noted that the former is a much larger and 

 blacker bird, and is further distinguished by having the base of tail 

 and the terminal band on the same, as well as the upper and under 

 tail-coverts, white. Young birds measured as follows : — J (no. 1 

 of Schlegel's Cat.), wing 13"6 inches, tail 7*9, tarsus 1-85 ; 2 (^o. 2 

 of Cat.), wing 14, tail 8, tarsus 1-9.
