"6 KOVITATES ZOOLOGICAE XXII. 1915. 



30. Crateropus fulvus fulvus (Desf.). 



It is cnrions how very few nests were fonud in the Oned N^a, where the bird 

 is common enough, and those we saw were empty. Only once, on the 25th, a boy 

 brought us three eggs, of which one got broken. 



31. Monticola solitarius solitarius (L.). 

 Evidently nesting near Hammam Meskontine. 



32. Oenanthe deserti homochroa (Tristr.). 



Nesting in small numbers near the Oaed N^a. Hard-set eggs (three oul.v) 

 were found on April 22, others (three and four) quite fresh on April 25. The eggs 

 are not distinguishable from those of Oenanthe hispanicn. Measurements have 

 been given, JS^ov. Zool. xxi. 1914, p. 198, under No. 65! By some unexplainable 

 error these measurements, as well as the two lines at the top of p. 199, were 

 misplaced under No. 65, while they belong of course to No. 63 ! 



33. Chelidon rustica (L.). 

 (Ilirunr/o rustica.) 



34. Hirundo urbica meridionalis Hart. 



Both Vheliihn rustica and Hirundo urbica meridionalis nest in Laghouat, 

 but farther south we have no evidence. In Laghouat //. urbica meridionalis 

 breeds in fair numbers under certain colonnades — several streets, the hotel, and 

 other buildings being colonnaded. C. rustica. breeds in small numbers. 



Both species of Swallows nest also at Sidi Maklonf and in other caravanserais 

 between Laghonat and Boghari, H. u)-bica sometimes in hundreds, C. rustica 

 always in a few pairs only. 



35. Apus melba melba (L.). 



On May 21 we received five fresh eggs, taken from nests under the tiles of 

 some building in Constantine, together with the female taken on a nest. The 

 five eggs were probably from three nests, but as to this no certainty conld be 

 gained. The bird is very pale {"tuneti" Tschusi), but I still doubt whether a 

 North African race can be separated. 



30. Apus apus apus (L.). 



In April a few were seen on the Hiissi-Kobib, but on the 22iid they were 

 quite numerous. 



37. Caprimulgus aegyptius saharae Erl. 



Ou April 24 a pair was found near Gamash, about fifteen kilometres from 

 Biskra. 



We were disappointed not to see a single specimen among the sands of 

 El-Arich nor near Hassi-Kebib, though we had seen and shot young birds in both 

 places in June 1912. In vain were we searching for them and waiting in the
