Other specimens from Iowa are intergrades with _spadix_, or if not with _spadix_, with the animal of northwestern Iowa which in some ways combines the characters of _longicauda_ and _spadix_. For example, no. 2665, Coe College, an adult male from Davenport, has the anterior part of the skull (all that is preserved) heavily ridged as in _spadix_ and in addition, the underparts are marked with the shade of reddish displayed by topotypes of _spadix_ and with some yellowish as seen in _longicauda_. The color pattern, however, is as in _primulina_. A young male, no. C-51, Iowa State College, from Kelley, Story County, has anteriorly truncate bullae as are more frequently found in the _longicauda-spadix_ stock of northwestern Iowa, than in _primulina_. In other respects, the animal, in so far as can be judged from the broken skull, agrees with _primulina_ as it certainly does in color, color pattern, and external measurements. An adult male, no. 499a, Iowa State College, from 2 miles east of Ledges St. Park, in Boone County, in short body, size of teeth, and size of skull, in so far as the broken parts can be measured, resembles _primulina_ more closely than it does any other subspecies. The long tail, long hind foot, wide extent of the light-colored underparts, and extension of the color of the underparts onto the hind feet are more as in _spadix_. Other intergrades with _spadix_ from Iowa are mentioned in the account of _spadix_. The specimen from Swartz, Louisiana, suggests intergradation with _arthuri_ in that the anteromedial part of the tympanic bulla is less inflated than in typical _primulina_. Intergrades with _longicauda_ are available from Riley and Pratt counties, Kansas. No. 7182, Univ. Kans., subadult male in winter pelage, from near Winkler, has a skull of larger size as in _longicauda_ with which race it seems to agree in large size of body, tail and hind foot, although the collector's measurements are lacking. Color pattern and relative proportions of the skull throughout are as in _primulina_. The young male, no. 3495, Univ. Kans., from Pratt, Kansas, agrees in external measurements and large size of skull with _longicauda_, but has the color and color pattern precisely as in _primulina_. The teeth are smaller as in _primulina_. Immaturity prevents judging of its relationships on the basis of relative proportions of the skull.
