neiv Species of StarUngs. 477 



The bird which it is proposed to call after my friend Dr. 

 Robert Collett was presented by him to the British Museum 

 in 1886^ and I have refrained from describing it up to this 

 time in hopes of meeting with some additionalspccimens, as the 

 locality of the one in question is not known. Having, how- 

 ever, now finished my studies of the Old-World Starlings, I 

 have come to the conclusion that Dr. Collett's specimen really 

 belongs to a distinct species, which may be diagnosed as 

 follows : —
