The Illinois population differs slightly from samples from more western localities in the smaller average number of vomerine teeth, in the poorly developed cirri, and in the usual irregularity of the rows of mid- dorsal dark spots. Nevertheless, the sam- ples from western Illinois are homogeneous, quite distinct from the eastern E. I. lotiffi- cauda, and the differences noted are not due to intergradation with the eastern form. Thirteen specimens from Adams County show the following variation: snout-vent length to mm.; total length 88 to 133 mm.; 13 costal grooves in 3 speci-. Fig. 36.—Distribution of Enrycea long'icauda. Vertical hatching indicates the presumed range of E. I. longicauda; horizontal hatching, the presumed range of E. I. melanoplriira; cross- hatching, the area of intergradation between the two subspecies; solid circles indicate local- ities represented by specimens examined dur- ing this study; open circles, localities repre- sented by published records believed to be valid. The lower map shows the total range of the species in the United States. mens, 14 in 10; toes of adpressed limbs overlapping by 1 costal fold to a separation of 2 folds; combined vomerine tooth counts 14 to 30 (average ) ; cirri present in 1 specimen, nasolabial tubercles in 12; scat- tered ventral flecks in 11 specimens, immac- ulate venters in 2. Intergrades of melanopleura X longicaudi have been discussed under the subspecies loiujicauda. Samples from Pike and Greene counties display some characters of longi- cauda but the melanopleura influence is sol pronounced that these specimens would keyj out as melanopleura. Habits.—This subspecies is similar to thej eastern long-tailed salamander in habitsJ The only difference that seems worthy ofj notic
