Qnadrato-jugal well developed; zygomatic arch complete, and always 

 present and relatively wider and more fully develoi^ed than iu T. hauri. 

 Maxiline distinctly notclied. Upper branch of the scapula considerably 

 longer than the inner branch (endo-scapnla) ; digits with distinct well- 

 developed webs. Number of pbalanges in the forefoot, 2-3-3-3-2; 

 hind foot, 2-3-3-3-2. Number of claws in the hind foot, 4. 



Carapace oblong in horizontal outline; transverse outline semi- 

 circnlar. Anterior margin but slightly curved; moderately compressed 

 above and median ridge distinct. The width of the carapace com- 

 pared to length varies from 10-12 to 10-14. First pleural plate more 

 than half as wide as long. Ground color varying from black, yellowish 

 olive or dark brown to very light dingy brown. The yellow spots are 

 arranged in radiating lines but are not connected. The j)lastron is 

 usually of a straw-yellow color with the dermal plates more or less 

 faintly bordered with black or dark brown. 



This species is found in regions adjacent to the Gulf coast of Florida, 

 Alabama, Louisiana, and Texas.

TERRAPENE BAURI, new species. 



Quadrato-jugal well developed; zygomatic arch complete, though 

 not as wide as in T. major. Webs absent. Number of phalanges in 

 the forefoot, 2-3-3-3-2; hind foot, 2-3-3-2-1. Number of claws on the 

 hind foot, 3. 



Carai^ace semicircular in transverse outline, im])erfectly oblong in 

 horizontal outline. Median ridge and keel distinct. First pleural i^late 

 more than three times as long as wide. Ratio of width to length of 

 the carapace approximately 10 to 13. 



Ground color of the carapace dark brown, sometimes slightly olive, 

 marked with yellow, arranged in radiating lines rather than single 

 spots; keel yellow. The markings of the carapace bear a very close 

 resemblance to the extreme western species T. ornata, a species from 

 which it is entirely separated geographically. Plastron yellowish with 

 but few markings.
