Goin and Goin (1951:29-33) have given an excellent brief account of behavior and seasonal schedule in a small colony of _E. laticeps_ near Gainesville, Florida, based on almost daily observations over a period of years. In view of the greatly different climatic conditions, the seasonal schedule is remarkably similar to that of _E. fasciatus_ in Kansas, and it seems that the minimum threshold temperatures required for activity are much higher in _laticeps_. Temperatures of 80° F. or above for several consecutive days seemed to be a necessary stimulus for emergence from hibernation; emergence was in the last week in March or the first week in April in Florida. Hatching was found to take place in late June or early July. Adults were last seen before retiring into dormancy in the latter half of September and young of the year remained active into October some two or three weeks later. The skinks observed all lived in hollow water-oaks. When the population was at an especially high level, in the late summer of 1949, each hollow oak was inhabited by one young and one adult. Territoriality and mutual exclusiveness of adults and even of young seems to be implied. The skinks were seen eating spiders, ants, and cockroaches. Neill (1950:115) mentions one sizable colony of _E. laticeps_ living in a treeless urban area, in Georgia and depending for shelter on piles of metal drums and other industrial equipment. Evidently, however, this was an exceptional situation. In another paper, Neill (1948b:109) described the specialized hibernation site requirements of _laticeps_ in Georgia; the skink retires inside large, rotting pine stumps, especially those that are leaning. He states (1948a:157) that in Georgia, _laticeps_ is most common in the Coastal Plain and is much less numerous above the Fall Line (the line between the Coastal Plain and the Piedmont). Deckert (1918:31) wrote of "_Plestiodon fasciatus_" in the vicinity of Jacksonville, Florida, where only _E. laticeps_ and _E. inexpectatus_ occur: "Inhabits hollow trees, always near water. Blue-tailed ones often live around human habitations." With regard to the ecological traits of _E. inexpectatus_ that distinguish it from _fasciatus_, authors are much less definite, and evidence is somewhat conflicting as the differences are relatively minor. Engels (1949:269) noted the occurrence of _E. inexpectatus_ on two low islands of submarine origin, off the North Carolina Coast, Harkers Island and Shackelford Banks, and he surmised that the absence from them of _E. fasciatus_ and _E. laticeps_ must have some ecological significance, since all three species occur on the adjacent mainland. Most of the island _inexpectatus_ were taken from beneath loose bark of standing trees, while mainland _fasciatus_ was taken from beneath loose bark of fallen trees.
