by comparison with their numbers in England. At Gibraltar this species is very much more common than in the places mentioned above.
P. hispaniolensis.—In Sardinia this species replaces the Common Sparrow, and is fairly numerous.
Fringilla cœlebs.—The Chaffinch was common everywhere except in Sardinia, where I did not observe it.
Linota cannabina.—The Linnet was common at Arosa Bay in May.
Pyrrhula europæa.—One Bullfinch was observed at Algeciras in November.
Emberiza miliaria.—The Corn-Bunting was fairly common at Arosa Bay.
E. cirlus.—A few Cirl Buntings were seen at Arosa Bay.
E. hortulana.—The Ortolan Bunting was seen a few times at Arosa Bay in May, where it was nesting.
Sturnus vulgaris.—Starlings occurred at Arosa Bay, but in remarkably small numbers, considering how well suited the country appeared to be to their wants. Elsewhere they were not seen.
Pyrrhocorax alpinus.—One specimen seen at Ronda.
Garrulus glandarius.—Except at Arosa Bay—in the woods around which they were fairly common—Jays were not observed.
Pica rustica.—The Magpie was fairly common at Arosa Bay.
Corvus corone.—The Carrion-Crow was by far the commonest of this family seen at Arosa Bay, where it swarmed everywhere.
C. corax.—There was at least one pair of Ravens breeding on the rock at Gibraltar, and probably others were there also. At Aranei Bay these birds were very common.
Alauda arvensis.—Sky-Larks were extremely common everywhere except in Sardinia.
A. brachydactyla.—The Short-toed Lark was noted only at Ronda.
Cypselus apus.—The Swift was very common at Gibraltar, where it first made its appearance during the last days of March. It was also common at Algeciras and about Arosa Bay.
C. melba.—The Alpine Swift was only noticed twice—a pair at Ronda in April, and a single specimen near the signal station at the top of the rock at Gibraltar in May.
