FIG. 2. A bare area along the rock fence at northern edge of pasture at Damm Farm. Ornate box turtles could nearly always be found foraging in cow dung here and in similar areas along other fences (June 28, 1958). [Illustration: PLATE 18] FIG. 1. A ravine in the southern part of the pasture at the Damm Farm (June 28, 1958). Small springs at the heads of such ravines produced marshy conditions at their bottoms and provided drinking water, in the form of shallow pools, for box turtles for at least part of the year. Banks of ravines provided suitable sites for the construction of nests and forms. FIG. 2. A mulberry tree on the bank of a ravine near northern edge of Damm pasture (June 28, 1958). Box turtles frequented the area beneath the tree when fruit fell to the ground in June and July. The ravine shown here filled with water after being dammed in June, 1956. [Illustration: PLATE 19] Representative stages in the spermatogenic cycle of _T. o. ornata_ (all specimens obtained in Douglas County, Kansas, 1955). FIGS. 1 to 5, respectively, are sections of seminiferous tubules obtained on May 17, June 14, July 15, Aug. 31, and Oct. 4. FIG. 6: seminiferous tubule of immature male (plastral length, 88 mm.), six years old, obtained on June 30. FIG. 7: section of epididymis from mature male obtained on April 17, three days after turtle emerged from hibernation; mature sperm form a continuous dark mass in center of epididymis. FIG. 8: sperm in uterine portion of oviduct of female obtained on April 18, 1954. Figs. 1 to 6 and 8 were photographed × 430, and were enlarged 1.4 times. Fig. 7 was photographed × 35, and was enlarged 1.4 times. [Illustration: PLATE 20] FIG. 1. Left ovary of mature female, prior to ovulation, May 15, 1956 (× 1). FIG. 2. Fresh corpus luteum, June 2, 1956 (× 4½). FIG. 3. Testes of mature male, August 31, 1955 (× 1). FIG. 4. Testes of mature male, April 14, 1956 (× 2). FIG. 5. Left ovary of subadult female (seven years old, plastral length, 114 mm.) that would have matured in approximately one year (× 1½). FIG. 6. Left ovary of juvenal female (11 years old, plastral length, 95 mm., × 1½). [Illustration: PLATE 21] FIG. 1. A trial nest cavity excavated by a gravid _T. o. ornata_ at the Damm Farm on June 8, 1956. The cavity was situated at the edge of a grassy area on the upper rim of a ravine embankment. Twelve-inch ruler shows scale. FIG. 2. A depression, resulting from an old post-hole, showing the openings made by three box turtles as they left their hibernacula in April, 1956 (photographed May 15, 1956). Twelve-inch ruler shows scale.
