Mammals -- Washington (State)
_Remarks._--Shrew-moles are present on Destruction Island, a small
island in the Pacific off the coast of Jefferson County. These moles are
large, and are like _gibbsii_. It is thought, however, that this
resemblance is due to convergent evolution rather than a once-continuous
range with _gibbsii_. It is significant that a shrew (_Sorex trowbridgii
destructioni_), the only other native land mammal on the island, differs
from its mainland counterpart in much the same way as does _Neurotrichus
g. gibbsii_ from _Neurotrichus g. minor_.
=Neurotrichus gibbsii minor= Dalquest and Burgner
_Neurotrichus gibbsii_ minor Dalquest and Burgner, Murrelet, 22:12,
April 30, 1941.
_Type._--Obtained on the University of Washington Campus, Seattle,
King County, Washington, by W. W. Dalquest on May 19, 1940; type in
the Museum of Vertebrate Zoölogy.
_Racial characters._--Size small; tail short; foreclaws light and
weak as compared to those of _gibbsii_, with ventral surfaces
curved.
_Measurements._--Eighty-five specimens (males and females) from
Seattle, King County, average: total length, 107.0; length of
tail, 35.3; length of hind foot, 15.0.
_Distribution._--The lowlands of western Washington. Marginal
records are: Mt. Vernon (Jackson, 1915: 97), Cottage Lake (W.W.D.)
and Yacolt (M. V.Z.).
Genus =Scapanus= Pomel
Moles
[Illustration: FIG. 23. Coast mole (_Scapanus orarius orarius_) left

B-18637.)]
Moles are of stocky build and have cylindrical, rounded bodies. The eyes
are tiny, nearly concealed in the fur. They have no external ears. The
legs are short; the forefeet wide, spadelike, and armed with powerful
claws. The fur is erect, not posteriorly directed. The color of the fur
is deep bluish or brownish slate. The short, nearly naked tail is pale
pink or whitish. Moles of this genus are found only along the Pacific
Coast of North America from southern Canada south into Baja California.
