6. Chrysemys reticulatus Bosc. 



Three specimens of Chrysemys reticulatus were secured in the 

 Okefinokee, two on Billy's Island and one on Honey Island. The 

 field notes of members of the party do not record any others as 

 having been seen, and it is probable that this is one of the less common 

 turtles of the swamp. The specimens secured agree with the pub- 

 lished descriptions and there can be little doubt as to the identity 

 of the species. 



The largest specimen, which is probably most tj^ical in all re- 

 spects save the markings, may be described briefly as follows: 



Carapace dull brown; thickly covered with fine reticulated grooves; 

 each plate with a distinct flat marginal border; shell rather high, 

 smooth in general outline; marginal plates with obsolete median 

 yellow line; under side of each marginal plate with black spot, 

 sometimes coalesced with that of the neighboring plate. Plastron 

 smooth, reddish-yellow, median plates with a distinct tinge of red. 

 Neck very long, skin loose, black. Head brown above with faint 

 yellow markings; yellow beneath with distinct reticulated brown 

 lines. Fore legs with wide yellow band in front, yellow below; 

 feet black beneath; claws long. Under surface of hind legs and 

 tail 3^ellow; hind legs with alternate black and yellow lines pos- 

 teriorly; tail with two black lines on under side. Measurements: 

 Length of carapace 8| inches, width 7 inches; length of plastron 

 6| inches, width 4 inches; height of shell 3| inches; width of head 

 lyg- inches; interorbital space less than f long diameter of the eye; 

 orbits distinctly upwards and outwards in direction. 



The second specimen differs from the first only in size, in ha\ing 

 the carapace somewhat indented and in the darker colors and less 

 conspicuous markings. In this specimen the lines on the under 

 side of the head are more nearly parallel, and the yellow color less 

 evident on the legs. The under side of the marginals would be 

 wholly without black spots but for three very indistinct ones. The 

 two spots on the bridge are widely separated. 



The smallest of the three specimens was found on Honey Island 

 and differs from the others only in the markings of the carapace 

 and in the more brilliant colors of the body. The carapace of this 

 specimen is smooth, without grooves, and beautifully decorated with
