The eggs of Oe. deserti hoinochro(t cannot be distingiiislied from those of 

 Oe. hispanica hispanica, though the latter are sometimes somewhat more glossy. 



W>. Oenanthe hispanica hispanica (L.) 



Seen freijueutlj' in the neighbourhood of Orau earlj' in April. Breeding at 

 Ain Sefra, where clutches of eggs were taken on April 1.") and 18. The nests 

 were not on the flat ground in the desert, but on steep banks along the river, or by a 

 roadside, placed in small cavities, but easily visible, and not in deep boles. The 

 eggs are, as a rule, indistinguisliable from those of Oe. deserti Iwmochron. They, 

 measure 19 x 15-5, 19-4 x 140, and IS'T x 14-7; 21-4 x 14-8, 21 x 14'9, 2U-5 x 14-3, 

 20 X 14-8, and 20-5 x 14-8 ; 19-8 x 14-6, 20-2 x 14-8, 20-2 x 14-9, 19-3 x 14-;"), and 

 20 X 15 ; 20 X If), 20-9 x 15-8, 20 x 15-9. and 20-3 x ]5-8mra. Tliey vary thns 

 considerably in shape and size. 



The young in the nest have pale grey down. 



OT. Diplootocus moussieri (Olphe-Galliard). 



By no means rare in the immediate neighbourhood of Tlemcen and on the hill- 

 sides south of that town. 



On Djebel Mekter, at an elevation of about 1600 m., a female was caught on 

 a nest with four fresh eggs. , The latter are of the blue type, which is evidently 

 commoner than the whitish variety. Another nest with four almost fresh eggs was 

 taken near Tlemcen on A])ril 19. This latter nest was placed at tlie foot of 

 a large somewhat overhanging boulder, of a height of 6 ft. The nest on Djebel 

 Mekter stood under some roots on the mountain slope. The female from that 

 mountain has a white chin-spot. 



OS. Luscinia megarhynchos Brehm. 



Cf. Noe. Zool xviii. p. 520. 



Nightingales were observed in the woods of Msila, near Oran, and they were 

 common and singing beautifully in the gardens of Tlemcen, Mansoura, and Agadir 

 (near Tlemcen). Also near Saida the song was enjoyed on May 20, though it 

 rained all day. The wings of a pair from Tlemcen measure about (rather worn) 

 80 and 81 mm. 



09. Troglodytes troglodytes kabylorum Hart. 



Wrens were not very rare, though not exactly common, in the oak-woods near 

 Orau (Msila) and south of Tlemcen. 



70. Chelidon rustica rustica (L.). 

 Swallows were common near and at Oran, Tlemcen, and Saida. They were also 

 seen once or twice at Ain Sefra, where, however, they might still have been on 

 passage. 



The wing of an adult male, picked up dead at Oran on Ajiril 10, measures 

 123 mm. 



71. Chelidon danrica rufula (Temm.). 



Cf. Hartert, \"u(j.pal. Fauna, i. p. 804 ; .V.^ii. Zuul. .wiii. p. 022. 



When motoring through the mountains between Tlemcen and Lalla iMarnia, on 

 April 27, we passed a stone bridge round which a pair of Swallows were flying, 

 which were at once recognised by their rnfous rumps as " Red-rnraped Swallows.''
