Figure 22.—Distribution of PUcotus townsendii Cooper (western section): 1, P. t. fal-lescens; 2, P. t. townsendii. Solid symbols, specimens examined; open symbols, otherrecords; encircled symbols, type localities. Cross-hatching indicates known areas ofintergradation between subspecies (between pallescens and townsendii in California,Nevada, Idaho, Oregon, Washington, and British Columbia; between pallescens andingens in northern Texas, Oklahoma, and Kansas; and between pallescens and australisin western Texas, Chihuahua, and Coahuila). Size averages medium for the subgenus; forearm averages relativelylong. Rostrum averages relatively long, dorsolaterally inflated, andusually not particularly depressed; anterior nares relatively large andusually rounded posteriorly (dorsal view). First upper incisor nor-mally without secondary cusp; upper canine averages less robust thanin northern populations; anterointernal cingular cusp of P* fre
