398 Mr. D. A. Bannermaii : Fh'st Impressions [Ibis, 



G. t. stiper/iaa, according to AVhitaker, inhabits tlie central 

 division of Tunisia and the less desert-like districts of the south. 



G. t. deichleri is an isabelline form which inhabits the 

 semi-desert inland country of southern Tunisia and does not 

 occur apparently north. of Gnfsa, while G. t. carolince is a 

 rufous form inhabiting tlie rocky inland plains of the south- 

 east of Tunisia. 



Until we have a very large series from Tunisia of these 

 Larks we catniot add anything to tlie distribution as given 

 by Mr, Whitaker in his ' Birds of Tunisia.' It seems desir- 

 able to ascertain the range of each particular form of both 

 the long-billed and short-billed Crested Larks with more 

 precision than has been done in the past. A list of actual 

 localities from which the various races have been obtained 

 would greatly help in defining the territory inhabited by the 

 six races up to now described. Dr. Hartert and Lord lioth- 

 schild have already carried this out as regards the Algerian 

 species and subspecies. 



As I did not collect anv Larks I can add nothino; to the 

 discussions which have already taken place, but should I 

 return to Tunisia I shall certainly obtain a series wherever 

 I go. That representatives of both the long-billed (Galerida 

 cristata) and short-billed (^Galerida theklcr) species are very 

 abundant I can testify from the tour I took in the northern 

 and central parts of the Regency, and I did not enter the 

 southern desert zone at all, where the Larks are of even 

 greater interest than those from the north. 



Tunisia is indeed a wonderful country for Larks of many 

 species. Apart from the several forms of Crested Lark (of 

 which there are at least six and possibly more), Whitaker 

 enumerates no fewer than fifteen other species and subspecies 

 belonging to the family Alaudida3 ; the genera Akcmon, 

 Chersopliiliis, Alauda, Ammomanes, Calandrella, Melano- 

 corypha, liliamplwcorys, and Otocorys, all being represented 

 by one or more forms. Unquestionably there still remains 

 good work to be done in determining the exact range of 

 these birds, particularl}'^ as regards the members of the genus 

 Galerida.
