1. ACCIPITER RUrOTIBIALIS^ Sp. n. 



This may be briefly described as a form of A. vircfatus, 

 from which it diflfers in its uniform chestnut under tail- 

 coverts and chestnut thighs. A. virgatus has the thighs 

 always much paler rufous or ashy, with more or less remains 

 of dusky cross-bars. The measurements are very small like- 

 wise. Total length 9-3 inches, culmen 0-4, wing 5-95, 

 tail 4*2, tarsus 1-8. The young male sent by Mr. Whitehead 

 is moulting direct from its striped plumage into the chestnut- 

 breasted plumage of the adult ; this seems never to be the 

 case with true A. virgatus, of which the Museum now pos- 

 sesses a large series. It likewise shows uniform rufous thighs. 

 It will probably be found that .A. rnfotibialis is a mountain 

 form of A. virgatus, peculiar to Kina Balu. Mr. Gurney 

 agrees with me that A. rufotibialis is recognizably distinct 

 from A. virgatus.
