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.)

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 Omithorhynchus and the spines 



of Echidna present this ordinary type of slope. 



2. Marsupials. 



3. Bodents. 



4. Insectivores. 



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



Ovidae ; Antilopidaj (except those mentioned below) ; Cer- 

 vidse ; Capra ; iSuidse (except one form noted) ; Camelidoe 

 and Girattida? (peculiar and noted more particularly below) ; 

 Hyracoidea : so far as observed, all present the Ordinary 

 Type.
