Certainly more than one species of Lark and Pipit were 
seen, but who would dare to name a Pipit from a passing 
car ! The return journey to Tunis added no fresh species to 
my list, save a couple of Ravens flying high overhead. The 
Moroccan Raven (Corvus corax tingitanus ) is an extremely 
abundant resident in Morocco, Algeria, and Tunisia. Once 
more we disturbed the Little Owls, which had returned to 
the same olive-tree from which we had already frightened 
them, and by 5 p.m. we were again in busy Tunis. 
Two days after returning from Dougga I made, in company 
with the Editor of 4 The Ibis,’ a delightful trip by car to the 
Arab city of Kairouan, thence journeying south to El Djem, 
the most southern point we reached, and thence again to Tunis 
via Susa, an insignificant port on the coast. 
Though birds were not the prime object, of our journey, 
the expedition afforded us an opportunity of seeing for the 
first time (at any rate as far as the writer was concerned) a 
number of interesting species, and we obtained a good first¬ 
hand knowledge of the varied types of country through 
which we passed. Whitaker, in the Introduction to his 
4 Birds of Tunisia,’ notes that “ Tunisia has been divided by 
geographers into three natural divisions or regions, each of 
these differing from the other two in its climate, hydrography, 
and topography, and consequently in its flora and fauna.” 
In the excellent map provided in his book these three regions 
are differently coloured, and the divisions can thus be. seen 
at a glance. Whereas Tunis itself lies at the north-east of 
the northern division, the towns we set out to visit are all 
situated in the central division, that which lies between the 
Atlas Mountains and the southern region of the Chotts and 
deserts. 
It was not until we’ had passed through the broken chain 
of mountains, which run in a north-easterly direction from 
El Oubira to Hammamet, and had gained the great plains 
which stretch almost uninterruptedly to Kairouan, that we 
noticed the change in the avifauna. North of the mountains 
we had seen only the usual species which frequent the more 
fertile parts of the Regency, such as Goldfinches, Brown
