Distribution in Colorado. — Known only from wooded areas in valleys of South Platte and Arkansas rivers (Fig. 27). Comparison.—From L. b. teliotis, a sub- species of the desert Southwest and the Pa- cific Coast, L. b. borealis differs in larger cranial size, larger ear with pronounced basal lobe, and generally duller color (G. S. Miller, Jr., 1897:111). Measurements.—External measurements of two males, and mean (and extreme) measure- ments of eleven females, all from the vicinity of Lawrenc

Measurements.—External measurements of two males, and mean (and extreme) measure- ments of eleven females, all from the vicinity of Lawrence, Douglas Co., Kansas, are (Cock- rum, 1952:77): 103, 110, (109-124); 48, 47, (50-60); 9, 9, (9-10); 12, 12, (12-13). Cranial measurements of two males and three females from the same locality include (Cockrum, op. cit. :87): greatest length of skull, , , , , ; condylobasal length, ,, , , ; zygomatic breadth, , , , , ; in- terorbital constriction, , , , , ; breadth of braincase, , , , , ; length of maxillary toothrow, , —, , , ; length of mandibular toothrow, , , , , Remarks.—My knowledge of the distribu- tion of L. borealis in Colorado is based en- tirely on records in the literature; specimens upon which these reports were based no longer are to be found. According to Lech- leitner (1969:55), there are published records of red bats from Boulder and Larimer coun-
