muzzle with a small whorl or star, and the hair passes in two 

 streams along the nasal up to the frontal area, diverging on its 

 way in a fan-shaped fashion, to coalesce on either side with the 

 hair round the orbits and that of the face and neck. In many- 

 forms, chiefly those with short hair, a clearly defined " parting " 

 is found in the middle line of the nasal and frontal regions ; in 

 those with longer and thicker hair no such " parting " is visible. 

 At about the junction of the frontal and parietal bones there is 

 commonly a further whorl or star, at which point further diver- 

 gences of hair-streams take place. This, which 1 would call for 

 convenience the Ordinary Type, can be seen in many hair-covered 

 mammals, especially those in which the hair is rather short. (See 

 fig. 1, Red Deer.)

HORSt 



Types of heads showing hair-slope on frontal and nasal regions, arrows 

 indicating general direction of slope. 



1 need do no more than enumerate those groups of animals 

 which conform to the Ordinary Type. 



1. Monotremes. — The fur of Ornithorhynchus and the spines 



of Echidna present this ordinary type of slope. 



2. Marsupials. 



3. EODENTS. 



4. Insectiyores. 



5. Ungulates.— Among the representatives of this great order, 



Ovidse ; j^ntilopidae (except those mentioned below) ; Cer- 

 vidse ; Capra ; Suidse (except one form noted) ; Camelidaj 

 and Giraftidae (peculiar and noted more particularly below) ; 

 Hyracoidea ; so far as observed, all present the Ordinary 

 Type.
