ound by digging
away a mound thought to be that of the pocket gopher, _Thomomys
sturgisi_. A trap set in one direction in the tunnel caught the mole; a
trap set in the other direction in the tunnel was later covered with
soil, evidently by a gopher. After the capture a thorough inspection of
the area revealed no "raised" tunnels, typical of _Scalopus_. A series
of _Thomomys_ was taken in this area in sets placed in tunnels found
under similar mounds. This locality was near the headquarters of the
Club Sierra del Carmen in a parklike stand of oak timber in a canyon, at
an elevation of 4950 ft. as recorded by our altimeter. The plant
association was judged to be characteristic of the Upper Sonoran
Life-zone, not far below the beginning of the Transition Life-zone. The
area was heavily grazed by goats, hogs and horses and had little grass
or other ground cover under the trees. The soil in this canyon was not
deep and consisted of a rocky, marly mixture, pale red in color,
evidently produced by weathering of the reddish volcanic rocks
bordering the canyon.

The Sierra del Carmen is a high, igneous range, surrounded for the most
part by Lower Sonoran plains and desert. Zoologically, these mountains
are poorly known. Few collectors have been in the area; most of these
have been afforded accommodations through the Club Sierra del Carmen
(Carmen Mountain Hunting Club), the members of which have been
especially interested in assisting naturalists. Several kinds of
mammals are known only from this "biological island" including the
pocket gopher mentioned above and the shrew, _Sorex milleri_. The
finding of a mole in the higher elevations of this range suggests that
moles may occur in other mountainous areas of Mexico.

In studying _Scalopus aquaticus texanus_, I noted that Allen (Bull.
Amer. Mus. Nat. Hist., 3:221, April 29, 1891) based the original
description on a single, unsexed specimen taken in Presidio County,
Texa
