74 NOVITATES ZOOLOGICAE XXII. IDItl. 



IT. Galerida cristata macrorhyncha Tristr. 



While during our short stay in 1912 we had only come across G. tkeklae 

 carolinae in the Oued N^a, we found this year the long-billed Crested Lark almost as 

 common. The two species were found close together, thongh generally the carolinae 

 kept more to hammada bordering the river-bed of the Oued Nf a, while macrorhjncha, 

 was met with, as a rule, in the tributary little oneds on its southern side, where 

 the ground was less stony and where much small vegetation had sprung up. Out on 

 the open hammada skylarks were never seen. In habits no marked difference was 

 noticed, though carolinae was seen soaring skywards when singing, macrorhyncha 

 only attempting to do so. 



From G. c. arenicola the G. c. macrorhyncha only differs in its generally darker 

 npperside (e.«pecially the crown) ; while the larger dimensions are only noticeable on 

 an average, when series are measured. 



18. Galerida cristata randonii Loche. 



(See Nov. Zool. xviii. pp. 488, 493.) 



As Mr. Rothschild and I have said before, G. c. ramlonii, if different, must be 

 restricted to the great plains of the Hants Plateaux. When rushing over them in 

 1911 we did not come across any form of G. cristata. In 1914 I decided to go to 

 Ain-Oussera, a wayside caravanserai where, according to Loche's Catalogue of 1858, 

 the type of randonii had been shot. It was there still, but very rare, and we only 

 managed to shoot two males. These, however, together with the old specimen from 

 the Riocour collection marked as randoni, show that this form has the bill stronger 

 and apparently, as a rule, longer, the chest more heavily spotted, the crown (and 

 l)erhaps the whole upperside as a rule) slightly darker. A larger series would also 

 probably show that the wings are a little longer. Our <? from the Coll. Riocour 

 has the wing 116, our two from Ain-Onssera llu'o and 117 mm. 



G. c. randonii was only seen on the clayey steppe, where some corn was trying 

 to grow, while G. theklae hilgerti was not rare along the roads. 



19. Anthus cervinus Pall. 



During the second half of April Anthus pratensis was often, A. trivialis some- 

 times, seen. On April 18 I saw two A. cervinus together, at once recognised by 

 their reddish throats. They were somewhat shy, and after shooting one the other 

 disappeared and was not seen again. 



20. Motacilla flava flava L. 



Flocks of Yellow Wagtails, apparently all M. f.jiam, were noticed almost daily 

 during our stay in the Oued Noa, also on May 5 at Tilrhempt. 



21. MotaciUa flava melanogrisea (Horn.) 



On April 18 a black-headed Wagtail was seen among many M. f. flara. 

 When shot it proved to be a female oi M.f. melanogrisea, with the throat and chest 

 pale whitish yellow.
