Observations on the Genus Cocreba. 489 



COLUMBA PALUMBUS. WoOcl-PigeOU. 



San Cristobal. — On March 21st flocks were seen among 

 the ilex and the lower pinsapos, but our observations during 

 the April visit being confined to higher elevations on this side 

 of the mountain, we did not notice whether they remained to 

 breed. (I'hey nested abundantly in the Goto Doiiana.) 



Sierra Nevada. — Not seen. 



Streptopelia turtur. Turtle-Dove. 



San Cristobal. — On April 24th at 11 a.m. six migrant 

 Turtle-Doves were resting on an esparto-grass plateau 

 at 4000 ft. 



Sierra Nevada. — Not seen. 



Caccabis rufa. Red-legged Partridge. 



For the complete status up to date of the Red-legged 

 Partridge in these parts the reader should refer to ' Un- 

 explored Spain.' The Sierra is not the true home of the 

 species in Andalucia, and yet two pairs were seen right up 

 among the mists and snow of the Sierra Nevada at 8500 ft., 

 and another at the summit of the Dornajo, 7000 ft. 



In San Cristobal the Red-legged Partridge was not 

 observed above 3000 ft.

 Collection at South Kensington ; upou a hundred and 

 fourteen in my own collection ; and upon two hundred and 

 eighty-four in the Hon. Walter Rothschild's collection at 

 Tring, which he was kind enough to place at my disposal.
