_Top_: A shell of _T. o. ornata_ (× ½) as it was found at the Damm Farm June 1, 1956. A serious injury (probably resulting from burns) had exposed a large area of dead bone on the carapace. _Center_: Same shell with some of scutes removed. _Bottom_: Same shell with dead bone removed to expose regenerating epidermis and bone. Note that the injury involved several of the neural bones; the turtle probably died as a result of this injury but not before regeneration was approximately one-half completed. _Terrapene ornata_ seems to concentrate its breeding season (laying, incubation, and hatching of eggs) more nearly in the middle of the warm season than does _T. c. carolina_. This concentration probably is an adaptation for breeding in open habitats where, under environmental temperatures less equable than in forest, eggs would develop more rapidly and hatch sooner but would be less able to survive winter temperatures. Males of _T. o. ornata_ become sexually mature when younger and smaller than females and rarely grow as large as females. Nichols (1939a:20) indicated the reverse to be true of _T. c. carolina_; Nichols further indicated that growth continued some six to eight years after puberty. Most individuals of _T. o. ornata_ attain maximum size within two to three years after puberty. Although it is difficult to be certain about the adaptive value of color and pattern, it seems that in box turtles, as in many other kinds of animals, patterns and colors most nearly blending with those of the habitat have some selective value in providing concealment from enemies. The pattern of linear radiations in _T. o. ornata_ closely resembles the patterns formed by light passing through grasses and associated vegetation and camouflages the turtle. In a similar manner, partial or complete loss of radial markings in _T. o. luteola_ seems to provide concealment in habitats where vegetation is sparse and where blending with the substrate is of survival value. The patterns of blotches and broken radiations in most of the subspecies of _T. carolina_ likewise provide camouflage by tending to match patterns formed by the light passing through a leafy canopy.
