prem<axillfie, coiii3led with the fact that the parietal extends 

 well on to the forehead, suggest that Aberdeen-Angus cattle 

 have in part sprung from a race domesticated in Central Asia. 

 While in two of the skulls of black polled Aberdeenshire cattle 

 hitherto examined the pi-emaxillse have an extensive connection 

 with the nasals, in the skull of a white polled " wild " Cadzow Ox 

 as in a black polled Galloway, the premaxillre bear practically the 

 same relation to the nasals and the lachrymals as in Bos 2^rivii- 

 genius, represented in text-fig. 65.

Front part of a horned Newstead skull in wliicli the premaxilte {F.M.) are short 

 and fail to reach tlie nasals {Na.). 



In most of the Newstead skidls examined the premaxill^e are 

 absent, but when the maxillse are present it is usually possible to 

 say whether or not the premaxillse had reached, or all but reached, 

 the nasals. The}^ probably reached the nasals in at least 90 per 

 cent, of the skulls of the Celtic Shorthorn {Bos longifrons) tyjDe, 

 and in about 70 per cent, of the skulls belonging to long-horn and 

 cross-bred animals. In the Celtic Shorthorn skulls the premaxilla^. 

 though long and almost in contact with the nasals, instead of 

 ending in a wedge-shaped process, are bifurcated and send a 

 process backwards over the maxilla as well as one upwards between 

 the maxilla and the nasal (text-fig. 73). In having the proximal 

 end forked the Celtic Shorthorn skulls agree with the skull of an
