The Zoologist — May, 1871. 



does not, however, agree with it. In the meanwhile I give it 

 under the same name as my predecessors. 



Galerita cristata, Boie. — Beyond Philippeville I met with this 

 form continually along the whole coast as far as Constantiue, and 

 still farther towards the south. This is the short-beaked form, 

 similar, as far as size and general appearance are concerned, to the 

 Spanish G. striata of Brehm. It is darker on the under side than 

 ours, with large compact spots on the neck and breast : the belly 

 is of a darker colour than in the other forms ; the crest is short. 



G. arenicola, Tristram. — This somewhat larger form than the 

 last is found on the southern slope of the Atlas below Batna. Like 

 the preceding species this one is short-beaked, but it may readily 

 be distinguished by its much lighter sand-colour. It is as much 

 spotted on the breast, which spots, however, do not reach as far as 

 the belly, that part being slightly tinted with a sandy colour. This 

 form is common, but it is the only one of its kind throughout the 

 whole high ground of El-Kantara. 



G. macrorhyncha, Tristram. — This new form first occurred about 

 the middle of our way from El-Kantara to the heights of El-Outaja, 

 our attention being drawn to it by the length and slenderness of its 

 body, by its more sandy colour, and especially by the length of 

 its curved and strongly arched beak. It has a longer crest than 

 the last species, and longer, narrower and paler spots on the breast. 

 This form appears exclusively on the Plain of El-Outaja and on 

 the heights round about, near Biskra, and on the borders of the 

 desert, in the vicinity of the oases. It is like the G. Randoni of 

 Loche, only that its beak is narrower and not so short as that of 

 the latter. 



G. isahelUna, Bp. — Seldom seen far into the desert: we mostly 

 found it on sand-dunes and stone-covered hills. It is the smallest 

 of the genus, with a short and straight beak, and is possessed of the 

 brightest and least uniform colouring. The spots on the breast are 

 very narrow and very bright. The following are the dimensions of 

 the above four species : —
