10 BIRDS OF TUNISIA 



G. cenops, Whitaker (Bull. 13. 0. C, vii, p. 18), from South 

 Marocco. 



G. g. whitakeri, Hartert (Die Vog. der Paliiarkt. Fauu. p. 33), from 

 North Marocco and possibly North Algeria. 



Regarding G. minor we know nothing of a positive nature, beyond 

 what has been told us by Verreaux himself {opus, cit.) and Loche 

 (Expl. Sci. Alg. Ois. i, p. 122), and the only specimen of it I have 

 been able to examine, is in the British Museum Collection. It is 

 not a very good one, and hardly available for comparison. I had 

 expected to find Verreaux's type in the Turati Collection at Milan, 

 which possesses so many of Loche's specimens, but together with 

 Professor Martorelli, the Director of the Museum, I searched in vain 

 for it there, although we found a specimen labelled G. minor, which 

 had apparently been obtained in Germany, and is merely a small 

 example of G. glandariiis. 



Of G. cenops the only examples at present known appear to be 

 those obtained by myself, four in number, from the Great Atlas Moun- 

 tains in South Marocco ; three, including the types, are in my own 

 collection, and one in that of the British Museum. These somewhat 

 resemble specimens of G. hyrcanus from Persia, but differ to a cer- 

 tain extent in coloration as well as in size. It is interesting to 

 find two closely allied forms so widely separated in their habitat. 

 Further particulars regarding G. cenops were given in the Ibis for 

 1898, p. (306. 



Dr. Hartert is of opinion that G. minor and G. cenops are but one 

 and the same bird, and this is quite possible, although I do not find 

 that Verreaux's description of the former entirely agrees with that of 

 the latter, especially in the wing measurement, which in G. minor is 

 given as 143 mm., or just about an inch less than it is in G. cenops. 

 Further specimens are evidently required to settle this point. 



G. g. lohitakeri, a Jay from North Marocco, and probably North 

 Algeria, which Dr. Hartert has done me the honour of naming after 

 me, is a form which resembles G. cervicalis in its white cheeks and 

 thi-oat, its black crest, aud grey back, but lacks the rich rufous 

 colouring of the nape and neck of that species, while in size and other 

 respects it more nearly resembles G. glandarius from Europe. A 

 specimen of this form, obtained by Captain Savile Eeid near Tangier, 

 exists in the British Museum Collection, and the Tring Museum 

 possesses several examples of it.
