_Rhithrodontomys inexspectatus_ Elliot, Field Columb. Mus.
zoAśl. ser., 3:145, February, 1903, type from PAitzcuaro,
MichoacAin.
_Reithrodontomys fulvescens toltecus_, Howell, N. Amer. Fauna,
36:51, June 5, 1914, part.
_Range_.--Central MichoacAin; limits of range unknown.
_Specimens examined_, 15: nos. 100278-100292, distributed by
localities as follows: 3 mi. N PAitzcuaro, 6,800 ft., 6; 3 mi. NW
PAitzcuaro, 6,700 ft., 3; 2 mi. W PAitzcuaro, 7,600 ft., 2; 2 mi. W
PAitzcuaro, 7,700 ft., 4.
_Remarks_.--Howell (1914:51) made _R. inexspectatus_ Elliot a synonym
of _R. f. toltecus_ and perhaps we should follow him in this. The
facts are that in our large series from the vicinity of PAitzcuaro, the
upper parts are more reddish than in _R. f. toltecus_ from the valley
of MA(C)xico, and more reddish than in _R. f. tenuis_ if we correctly
interpret Howell's (_op. cit._,:45) description of _R. f. tenuis_. In
the color of the underparts the series is, to us, indistinguishable
from topotypical _toltecus_ and therefore has more reddish underparts
than _R. f. tenuis_, as we know _R. f. tenuis_, from Howell's (_loc.
cit._) description. In size, the series from PAitzcuaro is intermediate
between _R. f. tenuis_ and _R. f. toltecus_ but nearer the latter.
