Abstract
During the spring of 1951, the U.S. Fish and Wildlife Service undertook the removal of sea otter, Enhydra lutris (L.), from the Aleutian Island of Amchitka, for the purpose of restocking range from which the animals have long been exterminated. The decision to undertake this activity was influenced by the nature of military operations planned for the island later the same year. The capture and removal of the otter were under the supervision of Mr. Robert D. Jones, Biologist, U.S. Fish and Wildlife Service. Heavy losses among the animals shortly after capture made the venture unsuccessful. Many deaths were concurrent among animals in the wild state. The writer was asked to investigate the causes of disease in the sea otter, and it is the purpose of this paper to report the results of these investigations.

Abstract
According to the work of Rausch (1953) , two species of helminth parasites, Porrocaecum decipiens (Krabbe, 1878) and Microphallus pirum (Afanas'ev, 1941), are pathogenic for the sea otter, Enhydra lutris (L.) , on the Aleutian Island of Amchitka. In continuation of investigations of sea otter mortality on Amchitka during the latter part of May and early June, 1952, the writer made an attempt to obtain information on the life cycles and developmental characteristics of these parasites. It is the purpose of this paper to report the results of these observations.
