the Little Atlas. Unlike the Great Tit and Bine Tit, it was 

 never seen outside the forests. Its notes seemed to me 

 much more like those of the Great Tit than those of our 

 English Coal Tit.

The Ultramarine Tit was fairly common wherever we 

 travelled, when there were trees of any sort. It was com- 

 mon and, I think, breeding at Biskra in a garden on the edge 

 of the desert at the beginning of March, and I found a nest 

 in a wild olive at H. Meskoutiue at the end of March, while 

 in the cedar-forest on the Little Atlas it was common and 

 breeding up to the highest altitudes.

 Les Glacieres. 



The Algerian and Tunisian form of the Creeper, as I have 

 already stated (op. supra cit.), differs from typical Certhia 

 hrachydactyla Brehm from Germany chiefly in its darker, 

 more " black-and-white/' and less rufous upper side and its 

 more heavily marked flanks. 



C. b. dorutheee Hartert from Cyprus is even less rufous on 

 the upper side than the Algerian form, while the flanks and 

 under tail-coverts are greyish brown instead of rufous brown. 



I may add that there is no need to compare this Algerian 

 form of C. brachydactyla to see that it is altogether different 

 from any form of C. familiaris. 



Creepers were common and breeding in the cedar- forest 

 on the Little Atlas at all altitudes. I found a half-finished 

 nest in a hole in a cedar on May 14.
