EASTERN NARROW-MOUTHED TOAD
Kansas State Threatened Species
The venter is mottled and the dorsum is brown or tan and usually bears a dark median wedge. There is a single metatarsal tubercle. The toe tips are round and tapered. the toes are not webbed.
The Eastern Narrowmouth Toad differs from the Great Plains Narrowmouth Toad in coloration and from other species in foot structure and coloration.
This small frog is known only from the extreme southeastern Cherokee County within the Spring River drainage basin. Most records are from the Ozarks Plateau; however several recent records indicate that it follows riparian corridors along Brush, Shawnee and Cow creeks to the north and west.

Call is a high drawn-out, insect-like "beeeeeeeeeeee." Many liken it to the bleating of a newborn lamb.

Growth and Longevity:
KU 218746, Cherokee County, Travis W. Taggart, Shane Eckhardt, Kelly J. Irwin, and Joseph T. Collins, 28 September 1991, 37 mm (1 7/16 inches), Collins (1993).
Not known from Kansas.
Collins (1982) extensively surveyed the Ozark Plateau for this taxon and discovered several new localities, doubling the number of known vouchers at the time (from 3 to 6). He suggested that this taxon be designated as state Endangered Species. Miller (1991) studied this frog in the Ozark Plateau and provided additional information on its distribution and habitat requirements.
Further efforts to study these frogs in Kansas should include surveys along Brush, Shawnee, and Cow creeks to better determine the northern and western limits of their range in the state.
