Diagnosis.—A small, stout, aquatic or terrestrial salamander (largest Illinois spec- imen 104 mm. in total length), fig. 30, with- out costal grooves; gular fold poorly de- veloped; cranial crests present; vomeropal- atine teeth in two longitudinal series; dor- sum yellow-brown, olive-green, or red- brown and sharply cut off from yellow of venter and lower sides; scattered black specks above and below; one or two dorso- lateral rows of small red dots, some of which are not margined with black or at least not completely encircled. The eft, a peculiar terrestrial stage found only in this salamander, differs from adults, which are aquatic, by the absence of fins on the tail, by the absence of secondary sexual charac- ters, and by the presence of a granular or warty skin and darker groundcolor. Variation.—Efts are difficult to sex, but the depth of the pits in the temporal region (hedonic glands) serves to identify at least some males. Adults in breeding ponds are easily sexed. The male possesses greatly en- larged hind legs with horny material on the inner sides, a swollen cloaca, and conspicu- ous dorsal tail crest during the breeding season, in addition to the deep hedonic pits at all times.
