Didelphis virginiana virginiana Kerr
Opossum
Didelphis virginiana Kerr. Anim. Kingd., p. 193, 1792.
Type locality.—Virginia
Description.—Slightly smaller than a house cat; body in older animals heavy and fat; tail long, naked, scaled and prehensile. Ears large, naked and black with white tips; muzzle elongate and pointed; color of fur variable; overhair usually white and underfur white tipped with black; guard hairs long and coarse but underfur soft and dense; forefoot with opposable thumb; females with abdominal pouch.
Remarks.—The opossum has been introduced from the eastern United States into California and Oregon and has become well established in those states. Recent records from Clear Lake, Skagit County, and South Bend, Pacific County, indicate that the opossum is now resident in Washington and it may be expected to increase and spread ([Scheffer], 1943). The animals may also enter the area about Walla Walla from Oregon. The source of the opossums which have appeared in Washington is not yet known.
Of this animal, Dr. Carl [Hartman] (1923: 347) has written:
"In the popular mind, the generation of no animal is so shrouded in mystery as that of the opossum. Throughout the country, among both whites and negroes, deeply rooted tradition has it that the opossum copulates through the nose and that the female blows the fruit of conception into the pouch. Other myths relating to details of the reproductive process in this species are current among the people.
"The growth of such legends need not surprise one, however, for the early birth of the embryos and the use of the pouch as an incubator certainly challenge the imagination. These phenomena attract the attention because they are unique, differing from the familiar method of rearing the young obtaining among the higher mammals, including man. Familiarity breeds contempt; the ordinary ceases to be marvelous. Thus on account of its rareness and its 'different' character the opossum, our only marsupial, figures in the folklore to a prominent degree."
