November 6 - Have been trapping for mice, etc., since last was 
written* Got one specimen of the kind of Perognathus so common at 
Santa Rosalia, and three more of the small species. Made another trip 
out to Santa Eulalia. Explored several mines in that vicinity for bats, 
but found none, Was told there are bats in some mines farther away, and 
which I did not have time to visit. Saw a Virgo dotm by the river this 
afternoon, same as one seen in Aleraeda when I first came here, I did 
not succeed in getting it, 
November 7 - Got about 15 specimens today. At last I caught same 
of the genus Perodipus 1 have been looking for, They live here as at 
Santa Rosalia in the soft sand often in the dry bed of the river, and 
are never found on the higher stony ground while both species of 
Bipod certs are never found elsewhere, She Perodipus and large Dipod ar/s 
make well defined runways which often run from one hole to another 20 
yards or more away. Got also two more specimens of the small Perognathus. 
November 8 - Got 9 specimens this morningj 4 large Perognathus. 2 of 
the Perodipus. and 5 Sltcagys. 
November 17 - Since last ms written I worked here with fair success 
until 10th, Got altogether 7 small Per ogna thus and some more of the 
larger species. Besides other things. The evening of the 10th I took 
the north bound train for Gallego, about 76 miles from here to look for 
prairie dogs between the latter place and laguna, the first station 
south from it. When I took the train here a dust storm ms blowing from 
the north and it had turned quite cold, I reached Gallego a little be- 
fore midnight and found a station and a few (4 or 5) Mexican hovels 
near it. The station was very small, I got permission to sleep in a 
little room used as waiting room and warehouse. When I awoke next morn- 
ing, I found the ground covered several inches deep in snow. I managed 
to get s (mb breakfast of tortillas, meat, and coffee, and started out to
