logicse, vol. iv. p. 144)^ I find that it runs so much into 

 G. isabellina, that it cannot well be separated from it. 



Galerida isabellina. 



A female, from Ogadel in June. This approaches closely 

 dark specimens I have of this Crested Lark from Tunisia. 



Galerida macrorhyncha. 



Seven skins of S an^ ? , from Mesfioua.Enzel, Isseremont, 

 and Tameshlot, in May and June. These are a dark rufous 

 form of the G. macrorhyncha type of Lark. 



Alauua arvensis. 



Two, (J and ? , from Schaf-el- Akab, end of February ; 

 the bird must, however, occur further south. 



CaLENDRELLA BrtACHYDACTYLA. 



A good series of S and ? , from Uled Aloo, Mequinez, Wed 

 Enger, and Dukalier, in March and April. Apparently not 

 occurring later in the south. 



Calandrella minor. 



A good series, ^ and ? , from Mazagan, Dukalier, Sierzet, 

 Enzela Imera, and Eas-el-Ain, between April and June. 



Melanocorypha calandra. 



A good series of S and ? , from Sebu river, Hawara, Ulcd 

 Aloo, and Dukalier, in March and April. Apparently not 

 met with later down south.

Resembles O. elwesi, but differs from that species in having 

 the upper wing-coverts of a uniform sandy-brown colour, 

 the same as the back, and not vinaceous, while the hind 

 crown and nape are of a rich rufescent hue, and the upper 

 throat of a pale sulphur-colour. The black of the lower 

 throat and of the cheeks is distinctly separated by a yellowish- 

 white patch, as in 0. alpestris, while the general colour of 

 the upper parts, the black band over the base of the bill, the 

 bill itself, and the long hornlets are all as in O. penicillata.
