104 UNIVERSITY OF KANSAS PUBLS., MUS. NAT. HIST. Class REPTILIA Order TESTUDINES Family Kinosternidae Kinosternon integrum Le Conte Kinosternon intergrum Le Conte, Proc. Acad. Nat. Sci. Philadelphia, 7:183, 1854 (type locality, Mexico). Remarks.—Three specimens identified as K. hirtipes by Taylor (1938:529) were later reidentified by Norman Hartweg (personal communication) as K. integrum. Examination of 55 specimens of K, integrum from Sinaloa and nine specimens of K. hirtipes from Chihuahua and Durango has revealed at least three characters which serve to separate these two confusing species. In K. hirtipes the plastron is narrower relative to the carapace, the gular is shorter relative to the suture separating the numerals and pectorals, and , the thighs of males bear patches of cornified scales posteriorly. In K. integrum the plastron is wider, the gular is longer, and there are no cornified scales on the thighs of males. To our knowledge, K. integrum is the only species of Kinosternon known definitely from Sinaloa. The measurements for 55 specimens are as follows: carapace length 36-180 (132), carapace width 33-113 (88), carapace width/ carapace length 0.62-0.92 (0.68). Excluding seven individuals with carapace lengths of less than 100 mm. the ratio is 0.62-0.75 (0.67) for the remaining 48 specimens. Kinosternon integrum was the turtle most commonly encountered during the field work. Mud turtles are found in all river drainages in the state and are taken often in roadside ponds, ditches, and on the road at night. Hatching turtles were found in late July, August, and September. Distribution in Sinaloa.—Found in association with permanent water throughout the state, up to an elevation of about 1100 meters. See Fig. 35. Specimens examined.—2.5 km. N Badiraguato 230 m.

Family Emydidae Chrysemys scripta hiltoni (Can) Pseudemys scripta hiltoni Carr, Amer. Mus. Novitates, 1181:1, Figs. 1-3, July 30, 1942 (type locality, Guirocoba, 28 miles southeast of Alamos, 1485 feet, Sonora). Chrysemys scripta [hiltoni]: McDowell, Proc. Zool, Soc. London, 143:274, September 1964. Remarks.—Ten specimens obtained from the Rio Fuerte and nearby lagoons in northern Sinaloa, 5-7 March, 1961, are typical hiltoni. Their measurements are: carapace length 125-295 (180), carapace width 100-215 (130), and shell depth 45-150 (70). The series includes two males. Marginal black spots are distinct on all specimens. Distribution in Sinaloa.—Probably occurs throughout the Rio Fuerte drainage system. See Fig. 36. Specimens examined.—4.8 km. NE San Miguel, Rio del Fuerte, 90 m. (•KU 63600-09). Additional record.—7 mi. N Los Mochis (SM 10585). Chrysemys scripta ornata (Cray) Emys omata Gray, Synopsis reptilium, p. 30, 1831 (type locality, Mazatlan, Sinaloa). Pseudemys scripta ornata: Carr, Herpetologica, 1:135, December 30, 1938. Chrysemys scripta [ornata}: McDowell, Proc. Zool. Soc. London, 143:274, September 1964. Remarks.—Three specimens from southern Sinaloa are typical ornata, with no indication of black smudge-like marks on the marginals that are characteristic of hiltoni. Measurements of an adult male, female, and juvenile are respectively: carapace length 151, 300, 34; carapace width 120, 235, 31; shell depth 54, 120, 18. intergradation between ornata and hiltoni may occur in north-central Sinaloa.
