Behle may be leucodon or they may be laticeps. They are found in rich soil of the grasslands - generally in the wet seepage areas in the swales, but found on the crest of the knolls. The incisors are whitish - more so at the tips and then tinged with straw yellow in middle, darker at base. Of very large size.
