35. •Phylloscopus bonelli bonelli fVieill.)- 



Cf. Niir. Zwil. xviii. p. 504. 



Bonelli's Warbler was common at In-Salah (April 18 to 'Z'Z), ami in the river- 

 beds of the southern Oued Mya region daring the end of April and l)cginniiig of 

 May. 



36. *Acrocephalus streperus streperus (Vieill.). 



Cf. N,n'. Znol. xviii. p. 50-t. 



On May 14 to 16 these Reed- Warblers were common and lustily singing in the 

 reeds of the Lake of El-Golea. In the very thick Arunilo donax it was, however, 

 very difficult to retrieve any specimen we shot, and so we secured only two, both 

 adult males. These had the testicles quite small, not in the least swollen, and 

 were, probably, not breeding there, but still on migration, notwithstanding the late 

 date. 



37. *Acrocephalu8 schoenobaenus (L.). 



Of. Nov. Zonl. xviii. p. 504. 



This species too was very common round the Lake of Rl-Golea in the middle of 

 May. They were singing, but the se.xual organs of the specimens we shot were not 

 ill llu^ least enlarged, and 1 doubt, tluTcfore, if they were breeding in the Sahara. 



In lUO'J Mr. Kothschild and 1 were convinced that this bird was breeding at 

 Lake Fetzara, but so far the eggs have not been [irocnrcd, and thus jiroof is still 

 wanting. 



[Acrocrplialax anindiiKu-fHx {\i.),\\\(i Great Reed- Warbler, was not met with 

 this year. Tristram (see Sale-catalogue of Eggs collected in Algerin, 1H.5,S, ji. 0) 

 says that it is found in Algeria wherever there are tall reeds and swamps, and lie 

 took eggs in the " province of Constantine " on June 1.") and 22.] 



3s. *Hippolais icterina (Vieill.). 



Cf. A'"i). Ziiu!. xviii. p. ,004. 



A male and female were shot in the gardens of El-Golea on May 13 and 14, 

 evidently on passage. 



3'.». 'Hippolais polyglotta (Vieill.). 



Cf. Niii\ Zniil. xviii. p. ."i05. 



A male was obtained on May 1, in the southernmost Oued Jlya, 6ii km. north of 

 Aiii Guettara, doubtless on [)assage. 



4u. 'Hippolais pallida opaca Cab. 



Cf. Niw. Zoid. xviii. p. .505. 



A female shot in the southernmost Oued Mya, 6o km. north of Am (tuettara. 

 May 1, doubtless on migration. Larger than //. j). reiseri (? wing 695), slightly 

 darker, and with the same, but a more powerful song. 



41. Hippolais pallida reiseri Hilgert. 



Cf. Nm: Ziid. xviii. p. 505. 



This bird, which is still scarce in collections, was not rare during the last days 

 of our stay in In-Salah, singing merrily in the datc-palius iuitl ponu'gnuiates. A few
