6. Notice of a rare Asiatic Pigeon. By Frederic Moore. 



The bird which I beg leave to bring before the Meeting belongs to 

 that group of Pigeons typified by the common Rockdove {Columba 

 livia, L.), being an intermediate species between it and the C. leu- 

 conota, Vigors, and has hitherto been known only as an inhabitant 

 of the mountainous and rocky parts of Dauria and Songaria, in Cen- 

 tral Asia. The specimen under examination was procured in Ladakh 

 by Captain Richard Strachey, and is the 



Columba rupestri s.

Description of Specimen from Ladakh. — Head, throat, and ear- 

 coverts darkish ash-colour ; the feathers round the neck glossed 

 with changeable dark green and reddish-purple ; middle of breast 

 vinous-brown ; upper part of the back, fore part of the wing, the 

 base of the secondaries, the tertiaries, and the lower part of the 

 breast pale ashy-grey ; primaries and speculars ashy-brown ; ter- 

 tiaries and the greater coverts with a subterminal black band ; lower 

 part of the back, rump, fore part of wings beneath, and sides of 

 body white ; abdomen and under tail-coverts ashy-white ; upper 

 tail-coverts and base of tail for three inches, ash-colour, the tail with 

 a black terminal band and a broad subterminal white band : the 

 latter band does not lessen in width, or curve to the tip of the outer- 

 most feather, as in C. leuconota, but is almost even, curving slightly 

 only towards the base of the outer feather ; the base of the outer 

 web of the outermost tail-feather is also white. Bill and legs smaller 

 than in C. leuconota, livia, or intermedia. 



Length of unmounted specimen 1 1|- inches ; of wing 9 inches ; tail 

 5^ inches, with its outer feather J inch less ; tarsus 1 inch ; mid toe 

 and claw 1^ inch ; hind toe and claw y^ths of an inch ; bill to frontal 

 plumes -^-ths, to gape -^ths of an inch. 



This species was also recently observed in Ladakh by Dr. A. 

 Leith Adams, as appears from the following note in his " List of 

 the Birds of Cashmere and Ladakh," published in the 'Proceed- 

 ings' of the Society for the present year {vide anted p. 187), wherein 

 it is stated that "flocks of a pied variety of C. livia (if indeed
