lines, presenting a somewhat different appearance from those recently 

 described from Alamogordo, N. I\I.^ 

 Liolepisma laterale (Say). 



Obtained from Poteau and Petit Jean Mt., Ark.; Sugar Loaf Mt.. 

 Wyandotte and Limestone Gap, I. T., and New Braunfels, Tex. 



Eumeces quinquelineatus (Linn.). 



A large series representing all age variations from Chadwick, Mo.; 

 Petit Jean Mt., Magazine Mt., Blue Mt. Station, Ark. ; South McAlester, 

 Limestone Gap, Sugar Loaf Mt., Wyandotte and Wister, I. T. 

 Thamnophis proxima (Say). 



Collected at High Bridge, Pecos river; New Braunfels and Devil's 

 river, Tex. 



The New Braunfels specimen has the dorsal stripe deep red. 



Ventrals 165, 167, 174. Caudals 84, 95. 



Natrix sipedon transversa (Hallowell). 



Four specimens from Devil's river and one from Honda, Tex. If 

 this and other races of water snakes are to be considered subspecies 

 of one group, sipedon must be used as the specific name, as already 

 adopted by Mr. A. E. Brown, as it occurs in the tenth edition of 

 Linnaeus, while fasciatus does not appear until the twelfth. 



Only the young specimens seem to have the transverse spots well 

 marked. 



Ventrals 145 (2), 147 (2), 153. Caudals 69, 71, 79, 82, 83. 

 Natrix sp. 



One very young specimen from Uinta, I. T., seems to differ from 

 N. s. transversa. Nearly uniform brown above with an obscure light 

 dorsal stripe, plain whitish below. Ventrals 130. Caudals 45. 

 3alvadora grahamiae Bd. anrt Girard. 



One specimen from New Braunfels, Tex. A'entrals 180. Caudals 

 89. 



Diadophis arnyi Keimicott. 



Ten specimens from Chadwick, Mo.; Magazine Mt., Ark., and Sugar 

 Loaf Mt., I. T. 



This series is quite uniform in color and pattern and the first row of 

 scales is blue-gray in all. It seems very questionable whether this is 

 identical with the collarless D. regalis of Chihuahua, and until we 

 know more of the Mexican representatives of the genus it will be best 

 to use Kennicott's name, which was based upon a specimen from Hyatt,
