Studies on the Helminth Fauna of Alaska. XIV. Some Cestode Parasites of the Aleutian Teal ( Anus crecca L.) With the Description of Diorchis longiovum n. sp.
The Aleutian teal (Anas Crecca nimia Friedmann) has been relatively unavailable for helminth investigations by American workers because its range in North America is restricted to the western-most Aleutian Islands. During some parasitological studies on Amchitka, Aleutian Islands, Alaska, in May and...
