Terrapene major (Agassiz). 



One specimen from Devil's river, Tex. 



While I have no material for comparison, this specimen agrees with 

 Mr. Taylor's description {Pr. U. S. N. M., 1894, p. 576), and certainly 

 can be referred to none of the others recognized in his monograph. 

 The locality is much farther west than any recorded in Mr. Taylor's 

 paper, the nearest point from which he had a specimen being Galveston. 

 Terrapene triunguis (Agassiz). 



A specimen from Limestone Gap, I. T., seems to be referable to this 

 species. Mr. Taylor {I.e., p. 581) states that "the Louisiana form 

 seems to be a dwarf variety of this species," as noticed by Agassiz, and 

 a series of twelve recently received from Avery's Island, La., through 

 the kindness of Mr. E. A. Mcllhenny, support this view. Inasmuch 

 as Agassiz's type of triunguis came from Louisiana, it is the larger 

 form that must be supplied with a name, should such a separation be 

 deemed desirable. 



The Indian Territory specimen before me is dull olive-brown, with 

 more or less obscure yellowish radiating lines or blotches on the plates 

 of the carapace, while the plastron is yellow mottled with small brown 

 spots. 



The Louisiana specimens vary from this same style of coloration 

 to dark brown with small rounded bright yellow spots, arranged some- 

 what in radiating lines but entirely disconnected, plastron usually 

 plain dull yellowish, sometimes with obscure transverse and radiating 

 bands of brown; spots on the head bright yellow and reddish-orange. 



The proportions of the two forms are as follows:
