Algerian bird and required a new name, and tliey proposed 

 to call it G. c. cartha(jinis (Klein. & Hilg. Orn. Men. 1905, 

 p. 188 : Tunis). In this tliey seem to have been quite 

 correct. 



The bird which Whitaker referred to as arenicola thoj 

 apparently split up, naming those from Gabes to Gafsa 

 Galerida crhtata (jafs>r, (Orn. Mon. 1904, p. 189 : Seggi), 

 while the birds from the region of the Chott el Djerid (Tozer, 

 Douz, Kebilli) they named Galerida cristata reichenoun (Orn. 

 Mon. 1905, p. 189 : Kebilli). Hilgert, in his (Catalogue of 

 the Erlanger Collection^ 1908, pp. 102-104:, again reviews 

 these Larks and upholds the three names. 



Hartert, in his Vog. Pal. Faun. yoI. i. p. xxvi, footnote, 

 states that he considers both gafscc and reiclienoxci to be 

 synonyms of arenicola, which he evidently believes to 

 range from the line El Kantara-Touggourt-Bledet-Ahmar 

 in Algeria eastwards through the deserts of southern Tunisia. 



The British Museum is singularly deficient in Crested 

 Larks from Tunisia and Algeria, but the few we have at our 

 disposal does not prove Hartert to be wrong ! It certainly 

 appears to me that the long-billed Crested Larks from the 

 extreme south-east corner of Tunisia (a district cut oft" from 

 the rest of the desert country by a range of mountains — the 

 Djebel Matmata) is distinct and requires a name, but as we 

 have not sufficient material from this region, I shall refrain 

 from giving it one for the present. Birds from Tatahouine 

 appear to be much more rufescent in colouring than either 

 so-called reichenowi or gafsa\ 



Of the short-billed group Whitaker recognised four forms 

 in Tunisia : (a) Galerida tliehlai major, (b) G. t. saperjiua, 

 (c) G. t. deicJderi, (d) G. t. Carolina'. 



Three of these names still hold good, but the bird which 

 inhabits the north of the Regency extending to the Atlas 

 Mts. which Whitaker called G. t. major, we now know by 

 the name of G. t. harterti — the same form which is found 

 in the north of Algeria. Mr. AVhitaker notes that the bird 

 found at the higher elevations is still darker than his major, 

 so that there may be yet another form.
