In June and July pocket gophers (Thomomys talpoides tenellus) were trapped in the vicinity of the Research Station. Study of the chromosomes of these animals, using the colchicine-marrow technique indicated a 2n number of 46. Of these, 8 pr. are metacentric, 4 pr. submetacentric, 8 pr. subtelocentric, and 2 pr. telocentric. There is a metacentric X chromosome and a dot Y chromosome. This subspecies has two less chromosomes that T. t. rostralis of the Laramie area. Project Number 143.
