the dark form from the coastal regions {L. e. algeriensis) nor the light desert form 

 {L. e. elegans), and that therefore it must be L. e. dochoni. A comparison with 

 our series proves this surmise to be correct. Our nine skins cannot be separated 

 from our twenty-three Maroccan skins, mostly from the districts around Mazagan, 

 Mogador, and the south-western Blaroccan Atlas. 



These birds were found on the plain west of Lalla Marnia, which is to a 

 great extent covered with masses of bushes of Zizi/j/hus lotus, and the two shot on 

 the 29th were got near the road in isolated Zizyphns bushes. 



On April 27 a clutch of five eggs was taken, one of which K'ot broken by the 

 Arab boy who fetched it out of an almost impenetrable thorn-bush. 



So far north we should have expected L. e. algei-iensis, which we only know, 

 so far, from the neighbourhood of Tanger, Alger and Lac Fetzara, and from 

 northernmost Tunisia. It will be most interesting to get more data about the 

 distribution of these Shrikes, and especially the two closely allied forms 

 L. e. algerieusis and doc/soni. 



36. Lanius senator senator L. 



Common near Gran and at Tlemcen. A female shot at Tleracen, on April 26, 

 has still a good many feathers of the underside with (more or less arrow-shaped) 

 bars. Also seen near Ain Sefra, where it probably nests. A S was shot at the 

 latter place on May 15. Common near Sai'da, where a clutch of four fresh eggs 

 was taken on May 19, and another of seven hard-set ones on the same day. 



37. Pycnonotus barbatus barbatus (Desf). 

 Heard on Djebel Khar, near Oran, April 12. 



38. Muscicapa hypoleuca hypoleuca fPall.). 



(" Muscicapa atrkapiUu " auct.) 



A male was shot near Oran on April 15. A number of females (or grey 

 males) were observed at Ai'n Sefra on May 7, two females were shot which 

 probably belong to M. h. hypoleuca, but as the females of M. h. speculigera — 

 notwithstanding the difference between the adult males — are probably not in 

 all cases separable from those of M. h. hypoleuca, we can only suppose that they 

 belong to the latter. 



39. Muscicapa striata Pall. 

 (" Muscicapa grisola " anct.) 



Flycatchers, evidently on migration, were shot at Lalla Marnia (27. iv. 1913) 

 and Ain Sefra (1.5. v. 1913). 



(Later on, at Hammam Rhira, during the last days of May, we proved beyond 

 doubt, by taking several clutches of eggs, that the Grey Flycatcher nests in 

 Northern Algeria. We have said before (Tex.'. Zool. xviii. p. 503) that we could 

 not distinguish a series of breeding birds from North and Central European 

 examples. We have now once more examined the birds shot on the breeding 

 ground in Algeria, and we find that they average rather small, the wings of the 

 males ranging only from 83-S6-5, those of females 81-85 mm., while in Europe 

 the wings of males vary from 84-90, females 82-87 mm. This would point to the
