both the Lado and the Cape foi-ms, in whicli they ai-e wanting. 

 The presence of posterior horns, coupled with the abortion of the 

 fi-ont hoi'n, is therefore a distinctive feature of the present foi-ni, 

 whicli might appi'opriately be called the Foui'-horned Girafle. 



Entering somewhat more fully into the details of the featui'es 

 pi-esented by the skull of this foi-m, it may be mentioned that, in 

 addition to the great size of the posterior, or occipital horns, it is 

 characterised by its generall}^ large dimensions, and more especi- 

 ally by the great length and massiveness of the main horns, of 

 which the extremities ai-e expanded in a knob-like manner. The 

 length of the horns, measvn-ed from the surface of the skvdl 

 between their bases, is 7 inches, against 5| inches in a male

skull of the Baringo Girafi'e collected by Sir H. Johnston. In a 

 gii'affe-skull from the Sudan in the Bi-itish Museum tlie horns 

 are, however, nearly as long as in the pi-esent specimen, but are 

 much more slender. In the Transvaal skull the basal length is 

 25 inches, against 24| inches in the aforesaid specimen of the 

 Baringo race. It is thus lai-ger than most, if not all, giraffe- 

 skulls from East Africa. On the other hand, it is exceeded in 

 this i-espect by the type, and only known, female skull of the 

 Nigerian G. c. peralta, of which the basal length is 26| inches. 

 This affords an indication of the very large dimensions presum- 

 ably attained b}^ the last-named race.
