PLATE XXII. 



Fig. I. — Dermatitis in Reindeer Fawn. 



This condition follows the penetration of larvae of the warble fly (Oedcmagcna tarandi). 



Fig. 2. — Screw Worms (Phormia terrae-novae) on Reindeer Skin. 



Infestation is common at the time of year when warble grubs are leaving the backs. When 

 infested with a large number the animal usually dies, hence the necessity for following the 

 methods advocated for prevention.
