290 Mr. J. II. Guruey, Jan., on the Ornithology of Ahjeria. 



habits certainly resemble those of the Chats, except that it 

 perches less on stones, and runs much more ; and in particular 

 it bears no resemblance to the genera Calandrella, Alauda, and 

 Galerida, with which it is usually associated. Its flight is far 

 from swift, and often very undulating; as it descends, after 

 poising itself a few moments in the air, its quivering wings 

 bend slightly forwards, and its body seems to sink ; but these 

 manoeuvres are doubtless confined to the spring. It has a 

 pleasing song, although its notes are weak. Length 5| to 

 6| inches ; expanse 13 inches. Food small black and yellow 

 seeds and flies. 



83. Ammomanes regulus, Bp. 



I only shot one specimen of this species, in the Mzab. It 

 comes exceedingly close to A. pallida (Cab.); but I am confirmed 

 in referring it to this species by Dr. Tristram. 



84. Otocorys bilopha (Temm.). Desert Horned Lark. 

 This was in some respects the most interesting bird which I 



met with in the course of my rambles ; and I regret that I was 

 prevented from bringing home a specimen. It was only met 

 with at Tilremt, halfway between Laghouat and Gardaia. 



85. Galerida cristata (L.). Crested Lark. 



Having, at my father's suggestion, compared Crested Larks 

 from Algiers and Blida with Spanish examples in Mr. Saunders's 

 collection, and others from dificrent parts of Europe, the Al- 

 gerian bird is found to have darker plumage, a smaller crest, 

 a smaller and diff'erently shaped bill, and a more rufous rump. 

 The black of the tail is also much stronger and deeper. 



86. Galerida abyssinica, Bp. Abyssinian Crested Lark. 

 Found in the Sahara, and identified for me by Dr. Tristram. 



87. Galerida macrorhyncha, Tristr. : Megalophonus ran- 

 doni, Loche. Long-billed Crested Lark. 



I first remarked this species at Ain-Oussera (where Capt. 

 Loche obtained it) on the 12th of IMarch, at which time they 

 were paired. It seems to be confined, like the Calandra, to level 

 plains, whereas Galerida abyssinica is found in the hills. They 

 walk with the crest up ; and when one has been on the ground,
