continued so until the end of September, when birds became 

 few, the last being noted on 21st OctoI)er. 



When we were navigating the Suez Canal numbers of 

 holes in the banks looking like Sand-^Iartius' burrows were 

 observed in August. 



Crete. — First seen 27th March, plentiful l]th April, No 

 note later. 



Athens. — 13th April, plentiful on migration. 



Lemnos. — On migration, 23i'd August-Gth September. 



Malta. — First seen on migration 29tli IMarch.

The Crag-jMartin was found locally plentiful near Platea 

 in mid-December, and in Crete it apparently Avinters and 

 has a remarkably early migration. 



In Crete on 11th February a single Crag-Martin flew 1)}% 

 evidently travelling. On 20th February tlie species had 

 ])ecome plentiful about Suda village, and the last two in- 

 dividuals were seen there on 23rd February. This apparently 

 completed the passage of the Crag-Martins, all, it was con- 

 sidered, being birds which had wintered in the mountainous 

 interior of Crete, and not in Africa, which suggests that they 

 do not breed in Crete, but no visit was made to the interior.

Egypt. — The following remarks necessarily include both 

 races, as they were not recognised apart in the field. 



The Nightjar was distinguished from all otiier migrants 

 by having the greatest duration of passage, and considering 

 tiiat except when disturbed the birds are only to be seen in the 

 twilight, it was remarkable how much in evidence they were. 

 The passage started at the end of August. Tn September 

 Nightjars were plentiful, in October even more so; in 

 November their numbers decreased and 23rd November is 

 the last record. The crepuscular feeding-habit of the 

 Nightjar rather lends itself to the suggestion that its times 

 of flight might diff"er somewhat from those of the Passeres.
