the sixth is an old adult male the
teeth of which are so much worn that only a few traces of the
reddish-brown pigment remain. His testes were 5 mm. long. These
specimens are from an area of intergradation between _S. v. obscurus_
and _S. v. monticola_. The length of the maxillary tooth-row in these
six specimens averaged 6.23 (6.1-6.4) millimeters. Comparison with
average measurements of 6.6 and 6.8 in samples of _S. v. obscurus_, and
of 5.9 in a sample of _S. v. monticola_ (Findley, 1955:64, 65) reveals
the intermediate size of the specimens from the Mesa Verde. The gap
between habitat suitable for _Sorex vagrans_ on the Mesa Verde and the
nearest record-station for _S. v. monticola_ to the south and west in
the Chuska Mountains is wider than the gap between the Mesa Verde and
the nearest record-station for _S. v. obscurus_ to the north and east,
one mile west of Mancos, 75971, 7000 feet, or at Silverton. On
geographic grounds the specimens from the Mesa Verde are referred to _S.
v. obscurus_. The two specimens from Morfield Canyon were trapped on
November 4, 1957, and are grayish above and silvery below. Their pelage
contrasts markedly with the dorsally brownish and ventrally buffy pelage
of the September-taken specimens from Prater Canyon.
Myotis californicus stephensi Dalquest California Myotis
_Specimens examined._---Total, 3: Rock Springs, 7400 ft., 69243,
69246, August 21 and 22, 1956; 4505 Denver Museum, within the Park
(exact locality not recorded), R.L. Landberg, July 27, 1931.
The specimens from Rock Springs were an adult male and a non-pregnant
adult female. Both were shot over the road in pinyon and juniper. The
specimens are referred to _M. c. stephensi_ on account of their
paleness, _stephensi_ being paler than _M. c. californicus_ from east of
Mesa Verde in Colorado.
Myotis evotis evotis (H. Allen) Long-eared Myotis
_Specimens examined._--Total, 4: Chickaree Draw, Prater Canyon,
8200 ft., MV 7841/507, probably in the summer of 1935; Rock
Springs, 7400 ft., 69241, August 23, 1956, and 69249, August 18,
1956; Museum, Headquarters, 6950 ft., 69251, August 24, 1956.
An adult male (69241) was taken in a Japanese mist net stretched fifteen
feet across a dirt road where it entered the stand of pinyon and juniper
at the south edge of the burn on Wetherill Mesa between 7:20 and 8:30
p.m.; at the same place and time I captured five other bats of four
species: _M
