tions of this fact are seen in the T. ornata of Texas and the T. trkinguis 

 of Louisiana and southwestern Arkansas and southeastern Indian 

 Territory. But, notwithstanding these conditions, the specific char- 

 acters are maintained throughout the range of each species, as has 

 been shown. 



Terrapene major may be said to be strictly a gulf species, having for 

 its range the gulf coast fiom the Rio Grande to Florida, possibly includ- 

 ing southern Georgia. The specimens examined by me seem to be larger 

 in the average than individuals of other species, and in general osteo- 

 logical characters tliey certainly represent the primitive form of the 

 genus. They possess a well-developed quadratojugal, a comi)lete zygo- 

 matic arch, and are distinguished from T. hauri by the number of 

 l)halanges, color pattern, and webbed digits, there being four claws on 

 each hind foot. 



Terrapene hauri may be said to belong to the peninsula of Florida, 

 possibly including southern Georgia. It resembles T. major in having 

 a complete bony zygomatic arch and T. triunguis in having but three toes 

 on the hind foot, while it differs from either in the number of its pha- 

 langes. The coh)r markings of the type, excepting plastron, are almost 

 identical with T. ornata, a species from which T. hauri is completely 

 separated both by osteological characters and geograpliically. The 

 specimens mentioned by xVgassiz as three-toed specimens of T. Caro- 

 lina from North Carolina, and T. triunguis from Georgia may belong to 

 tins species. 



Terrapene Carolina is found in the northeastern United States, extend- 

 ing from the St. Lawrence and Great Lakes south to the Caroliuas and 

 Tennessee and west to the Mississippi River in Kentucky and to east- 

 ern Illinois.* This species seems to exist in greatest abundance in 

 New Jersey and adjacent regions, but Dr. Hinds informs me that it is 

 very common at Lebanon, Tenn. It seems to be, in a certain sense, the 

 mountain species, being found thoughout the mountains of Pennsyl- 

 vania, as well as elsewhere, and seems to be coextensive with the Alle- 

 gany range southward. It is characterized by its rudimentary quad- 

 rato-Jugal, the hooked upper jaw, and the presence of a distinct keel 

 on the carapace, the number of phalanges, and its slightly webbed 

 digits. 



* Unfortunately I am iinable to speak definitely as to the precise western limit of 

 T. Carolina nortli of the Ohio River. The specimens reported by Prof. H. Garman 

 as from various points in southwestern Illinois are inaccessible at the time of writ- 

 ing, owing to alterations now being made in the museum at Champaign, 111. Prof. 

 W. K. Higley, in his catalogue of "Wisconsin reptiles, mentions T. Carolina as col- 

 lected at the following places in Wisconsin, namely, Walmouth County, two speci- 

 mens; Milwaukee; Pine Lake; La Crosse; and Green Bay. Not having had an 

 opportunity to examine Prof. Higley's specimens, I have been unable to verify his 

 idcntiiications. Mr. Hurter, in his catalogue of St. Louis reptiles, mentions one 

 specimen of T. Carolina, but since it is the only one which has been found in that 

 locality he rather infers that it was brought into St. Louis. This inference is made 

 more probable by the fact that the individual was found in the elevator yards.
