built of mud and had a few feathers in it. At the end of October or beginning of 

 November flocks of about eight to twenty birds appear at tlie sea-side in the neigh- 

 bourhood of Oporto, and remain till about the end of Eebruary or the beginning of 

 March." As stated by the late M. Favier, it is " nearly as common as the House- 

 Martin about Tangier. Sometimes they pass in large flights, crossing the Straits in 

 February and March, returning in October and November." Capt. Savile Reid, during his 

 winter residence in Morocco, states that the species was seen by him in the Laraish Valley 

 on two consecutive warm sunny days, but not at any other time or place. Mr. Tyrwhitt 

 Drake noticed it near Tctuan towards the end of March, but only in very small numbers. 



In Algeria, Loche says, the bird is not very plentiful, but he found it uestiag in the 

 gorges of Chiffa. Malherbe speaks of it as a common bird at Bone, where it occurs in 

 larg'e numbers on migration in December. Canon Tristram states that in the Eastern 

 Atlas it is found as a resident, and he has noticed it in every month from September to 

 July. He also saw two in December in a ravine in the M'Zab country. Mr. W. T. H. 

 Chambers states that he recognized the species in Tripoli on one occasion only, and it 

 struck him to be " an old Nile acquaintance." It is quite possible that his instinct was 

 right, and that the bird he saw was C. ohsoleta, which is the species of the Nile, and 

 not G. rupestris at all. 



Major A. von Homeyer noticed the Eock-Swallow as a bird of passage in the Balearic 

 Islands. There is doubtless some mistake in Schembri's statement that the present 

 species is rather common in Malta both in the spring and autumn migrations, for Mr. C. 

 A. Wright at first stated that he never met witli a single specimen during his long 

 residence in the island. Subsequently, however, he did procure the species from Gozo 

 in March, and he received the following note from the late Professor Leith Adams : — 

 " I have just returned from Gozo : — Feb. 22, ilabato, Gozo. A pair have been sporting 

 about the foot and sunny side of the square all day. Feb. 23. Weather very cold — 

 even snow fell to-day ; but nevertheless I saw a flock of ten sporting about in the gorge 

 of Schlendi. I have noticed this Swallow about Ilabato in summer, but I have not 

 been able to confirm its identity till yesterday. I tliink, perhaps, individuals remain 

 throughout the year in Gozo." 



In Sardinia the late Mr. Basil Brooke recorded the Crag-Martin as common and 

 resident. Count Salvadori has given the following note on his experiences in the 

 island : — " Its name of RoncUne raarina may be derived from the fact that it frequents 

 eaves near the coast. I saw it in January about the Grotta dei Colombi. It is also 

 met with in the interior. I observed many inhabiting the beautiful Grotto of Oridda, 

 near Domus Novas, and also in the rugged rocky mountains. In tlie begiiming of April 

 I saAV some at Mount Ogliastra, near the Flumendosa ; and later (about the middle of 

 April) near Capoterra, at a creek, where they were collecting some clay for building 

 their nests. I do not know anything at all about their visiting the towns, which, as 

 Cara states, positively takes place after the other Swallows have left." 



Mr. J. Whitehead writes concerning the species in Corsica : — " Fairly common
