PLATE XXII, 
Fig. I. — Dermatitis in Reindeer Fawn. 
This condition follows the penetration of larvae of the warble fly {Ocdcmagcna 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.
