250 Mr. D. A, Bannerman on an Orn/tholoffical 



Oliva, and were met with in tlie north of the island in all places 

 favourable to them, even in the interior. In 1905 he found them 

 at Rio de las Palmas. This is the first mention of this species 

 west of the central range of hills. 

 1913. In the route which I followed [vide Map, in Part I. PI. II.], starting 

 from Puerto Cabras and crossing to Toston on the north-west 

 coast, we first met with these Chats between Caldereta and 

 Oliva, several being seen there. We next found them in he 

 Tamarisk valley of La Pena [vide Part I. PL III. fig. 1], and 

 particularly towards the upper part of this barranco [vide Part . 

 PI. IV. fig. 1]. In this diied-up water-course Saxicula d. 

 dacotice was plentiful, but once the ascent to Betancuria had 

 begun we saw no more of the Chats until we had crossed the 

 dividing range and gained the plains. At Antigua I saw 

 single young bird which had evidently been reared in the 

 neighbourhood. None were seen near Puerto Cabras, but we 

 again noticed them near the beach at Gran Tarajal. 



From these notes it will be seen that these interesting 

 Chats are now pretty well distributed over the island, but 

 curiously enough they have, so far as we know^ never yet 

 crossed the dividing strait to Lanzarote. There is almost 

 always a strong breeze blowing in the eastern islands, and as 

 these small birds find such difficulty in battling with the 

 wind, it is probable that this is the chief factor in confining 

 their distribution to the one island. For some account of 

 their habits see Part I. of this paper, pp. 47-8. 



A good, series was obtained from various parts of Fuerte- 

 ventura.

This Chat is confined to the outlying islets of Montana 

 Clara and AUegranza. A full description and account of 

 this interesting new subspecies is given in Part I. of this 

 paper {vide supra). 



A series was obtained, in Montana Clara and AUegranza 

 showing several stages of plumage. 



Bill black; iris dark hazel; legs black.
