278 Capt. Lynes on the Ornithology [Ibis, 



Part III. 

 Results and Conclusions. 



The Ornithological novelties, Sitta r. atlas, Eritliacus r. 

 atlas, and the breeding o£ Eremopldla a. atlas and Parus 

 ater atlas, are perhaps smaller '' results " than might have 

 been expected ; on the other hand, to fill in a blank area on 

 the (Ornithological) map of Marocco, to extend the range o£ 

 some of the subspecies as Coal-Tit and Shore-Lark, hitherto 

 known only in the Great-Atlas, and others as the Skylark, 

 not known to breed in Marocco, to confirm certain diagnoses 

 founded on small material, and to add some grist to the mill 

 of museums from which we enjoy many privileges, is, I feel, 

 ample reward (or excuse !) for my i>leasant holiday. 



Before passing on to the systematic catalogue with which 

 I proi)Ose to conclude this paper, and though aware that 

 these trifles of fresh knowledge of the Class best fitted for 

 natural dispersal, is a mere drop in the ocean of fact still 

 required before any stable theory can be founded, I am loth 

 to leave the subject of geographical distribution without a 

 word or two, if only to pick up the few threads of speculation 

 written by the illustrious Hooker nearly 50 years ago on 

 the origin of the Maioccan Mountain-Flora*. Sir Joseph 

 Hooker, reviewing the botanical results of his expedition 

 in 1871 to the upper regions of the Great-Atlas, while 

 remarking that "we only possess a fragment of its Flora, 

 and future exploration may largely modify our conclusions 

 " found that : — 



(a) " nothing indicates any special connection between 



the Floras .... of the higher zones of the Great- 

 Atlas, Algerian-Atlas, and Sierras of Andalusia." 



(b) " the absence of distinct generic types is most marked/' 



[(■) "in species .... the Mountain-flora of the Great-Atlas 

 differs widely from that of the Andalusian Sierras, 

 despite their comparatively small separation and the
