Mr. D. A. Banner man : First Impressions [Ibis, 
G. t. superflua , according to Whitaker, inhabits the 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 Gafsa, while G. t. Carolines is a 
rufous form inhabiting the rocky inland plains of the south¬ 
east of Tunisia. 
Until we have a very large series from Tunisia of these 
Larks we cannot add anything to the distribution as given 
by Mr. Whitaker in his 4 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 iD 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 Roth¬ 
schild have already carried this out as regards the Algerian 
species and subspecies. 
As I did not collect any Larks I can add nothing 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 tliehlce) 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 Alaudidse; the genera Alcemon , 
Chersophilus , Alauda , Ammomanes , Calandrella , Melano - 
corypha , Rliampliocorys , 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, particularly as regards the members of the genus 
Galerida.
