Harwood (1932:65) examined for endoparasites nine _E. fasciatus_ along with many other reptiles and amphibians collected near Houston, Texas. Most of them were infested and five kinds of helminths were identified. Two of the skinks were infested with _Oswaldocruzia pipiens_, a spirurid nematode that was also present in various other lizards, snakes, toads and frogs from the same region; four had _Comocercoides dukae_, an oxyurid nematode also present in various lizards, snakes, turtles, and frogs; one had in its intestine _Oochoristica eumecis_, named as a new species by Harwood, and found only in _Eumeces_; one contained _Cysticercus_ sp. in its body cavity, present in great abundance as white globular structures .6 mm. in diameter (Harwood states that possibly these were larvae of _Oochoristica_). One skink contained _Mesocoelium americanum_, a dicrocoelid trematode which was found also in the brown skink (_Scincella laterale_) and DeKay's snake (_Storeria dekayi_). The ectoparasites of these skinks consist mainly of chiggers. Wharton (1952:135) lists three species; _Trombicula alfreddugesi_, _T. splendens_, and _T. gurneyi_. The first species is the common pest chigger of humans and domestic animals in the United States, and south through tropical America. Wharton lists 136 known hosts which are fairly evenly divided among mammals, birds and reptiles; he lists four kinds of frogs and toads. _Trombicula splendens_ is a similar and closely related species which has been recorded from thirty-eight vertebrate hosts including mammals, birds, reptiles, and a tree-toad. _Trombicula gurneyi_ belongs to a separate subgenus and it was originally recorded from _Eumeces fasciatus_ which seems to be one of the principal hosts. Two of these mites, _T. alfreddugesi_ and _T. gurneyi_, were on skinks collected on the Reservation, and nearby areas. A four year study of the chiggers in this general region by Loomis (MS), Wolfenbarger (1953) and Kardos (MS) has clarified the ecological relationships of the several kinds of chiggers present, including their local distribution with respect to vegetation, soil type, moisture and temperature, host preferences, and seasonal occurrence. At the quarry, Rat Woods and the pond rock pile, the chigger population consisted chiefly of _T. alfreddugesi_, while at Skink Woods _T. gurneyi_ was also abundant. In some local situations where they are among the most abundant of vertebrates the skinks probably are important as hosts of _T. gurneyi_. An individual skink may have dozens of chiggers on it at one time but usually there are fewer.
