other liand, I find that de Winton's O. c. reticulata ' does not 

 appear to intergrade with the ordinary one at all, and should 

 therefore be called a species, O. reticulata, confined to Somali, the 

 EiidoK region, and jNTortheru British East Africa. I may also add

that the more skulls of Giraffes that I examine the more distinct 

 does the Western form, O. c. peralta, appear to be; bat having no 

 further material than the typical skttll, I can as yet add nothing to 

 my original account, 



' In Mr. de Winton's admirable paper on G-iraffes (P, Z. S. 1897, p. 273) all 

 the notes and descriptions of the " Northern Giraffe " based on Mr. Nenmann's 

 •Loroghi Giraffe really refer to G. reticulata, which was described later as a 

 snbspecies (Ann. Mag. N. H. (7) iv. p. 211, 1899). The asserted absence of 

 intergradation in East Africa between tlie " Northern " and Southern Giraffes is 

 therefore to be nnderstood as an absence of intergradation between G. reticulata 

 and the ordinary form.
