452 THE ZOOLOGIST. 



Muscicapa grisola. — One pair of Spotted Flycatchers was 

 noticed in some small gardens on the North Front at Gibraltar 

 in May. A few specimens were also seen at Arosa Bay in the 

 same month. 



Hirundo rustica. — The Swallow was common everywhere, and, 

 though naturally only observed at Arosa Bay in the spring, it was 

 still present at Gibraltar in the first week of November. At 

 Algeciras this bird was nesting, and had full clutches of eggs on 

 April 8th. 



Chelidon urbica. — The Martin was as common as the Swallow, 

 and occurred for the most part with it ; in Sardinia, as far as my 

 scanty observation permitted, it seemed much the commoner of 

 the two species. 



Cotile rupestris. — The Crag- Swallow was noted in three locali- 

 ties only. First, it was seen on a hill on the Spanish mainland 

 facing the North Front in the month of November, at an elevation 

 of about 500 ft. At Ronda, a town about eighty miles inland from 

 Gibraltar, having an elevation of 2500 ft., and divided into two 

 parts by a deep narrow gorge called the Tajo. This gorge is 

 about 1000 ft. in depth, and there, in company with the Common 

 Swallow, this species was observed in hundreds. The birds 

 seemed to be very tame, and, besides frequenting the gorge, flew 

 in and out among the houses just as the Common Swallows do. 

 At Aranei Bay, in Sardinia, a few pairs were observed at the end 

 of April hawking about after their prey down at the sea-level, as 

 well as up the sides of the hills, and in the valleys. This bird 

 was plentiful at Gibraltar in November and December, 1899. 



Carduelis elegans. — Many Goldfinches were noted at Arosa 

 Bay in March, and all were then paired. In May they had ap- 

 parently considerably diminished in numbers, probably, however, 

 many having gone elsewhere to breed. At Algeciras, in Novem- 

 ber, a few specimens were observed, and a flock of five hung 

 about the rock at Gibraltar for a few days in March. 



Serinus hortulanus. — The Serin was fairly common at Arosa 

 Bay in May, where it was then nesting. 



Ligurinus chloris* — Greenfinches were very common at Arosa 

 Bay. 



Passer domesticus. — Though fairly common in the towns and 

 villages about Arosa Bay and at Algeciras, Sparrows were scarce
