THE BIRDS OF ALGERIA. 13 



not so inseparably associated with that tree. An 

 example I shot at Lambessa in the Aurcs was 

 much paler in colouration than the average. 



14. The Corn Crakp: Crex pratemis, Bechstein, 

 is a resident in Algeria, but nowhere common, the 

 country not being suited to its requirements, 

 especially in summer. Taczanowski saw it only 

 on one occasion. 



15. The Spotted Crake Crex porzana^ Linnaeus, 

 is chiefly a winter visitor to Algeria, and at that 

 season is very widely distributed. Taczanowski 

 states that it is to be met with everywhere, but its 

 summer range is undetermined. 



16. Baillon's Crake Crex bailloni (Vieillot), is 

 locally a resident throughout Algeria in all portions 

 of the country suited to its requirements. In the 

 Sahara sub-region, as might naturally be supposed, 

 it appears to be only a winter visitant. 



17. The Little Crake Crex parva (Scopoli), is 

 a local resident in Algeria, but is not included by 

 Taczanow^ski nor Canon Tristram. I only met with 

 this species in the oasis of Biskra in the Sahara 

 sub-region, where it was apparently breeding. 



18. The Water Rail Ral/its aquaticus, Linnccus, 

 is a resident in Algeria, but is largely increased in 

 numbers in winter by migrants from Europe.
