_Range._--Below _Quercus_ belt, probably throughout western half of
state.
_Specimen examined_, 1: no. 100062, 1 mi. E and 6 mi. S TacAimbaro,
4,000 ft.
_Remarks._--The one unsexed subadult measures 5.5 mm. from Ml to M3
inclusive, which measurement is near the minimum that Tate (1933:
table 1, Sec. 5) records for this subspecies but larger than the
maximum that he (_loc. cit._) records for the subspecies _sinaloae_
which occurs to the northward of MichoacAin. Tate (_op. cit._:141)
lists two other specimens from Los Reyes. Our specimen was caught in a
mouse trap set in dry grass between a sugar cane field and a patch of
banana trees.
