20 ON THE ZOOLOGICAL POSITION OF TEXAS. 



Above, light brown ; below, pale greenish ; anteriorly, straw colored ; a 

 light narrow baud from the superciliary border continued along the 

 body and tail, separated from that of the opposite side by six scales, and 

 with a strong black border above. Below it, a deep brown or black 

 band one and two half scales wide, which is bounded below by another 

 light line; this is in turn bordered by a narrow brown line below, which 

 docs not extend like the other bands on the tail. The head and lips are 

 pale brown, and the only head bands are posterior to the orbits. Length 

 of head and body, .078; to ear from muzzle, .013; of fore limb, .015; of 

 hind limb, .019. 



This elegant species belongs to the same group as the last, and differs 

 from the U. antliracinus and U. tetragrammus in the same characters. 

 It differs from the E. hrevilineatus in the higher loreal plates, the much 

 smaller limbs, and totally in the coloration. One specimen only is in 

 my collection; it was procured near Dallas by Mr. Boll. In size, it is 

 above the average in the genus. 



Oligosoma laterale Say. Tliis species is abundant in many different 

 regions of Texas, as at Dallas, Washington, Helotes, San Geronimo Creek, 

 and the Upper Medina. 



OPHTDTA. 



Stenostoma dulce B. & G. Found not unfrequently by Mr. Marnock 

 under stones near Helotes, Bexar County, also from Erath County from 

 Mr. Boll. 



Tantilla gracilis B. & G. Not rare at Helotes. 



Tantilla nigricejps Kenn. I procured one specimen, which was taken 

 near San Antonio by Mr. Kallteyer. A second was found by Mr. Boll 

 somewhere between the upper waters of the Brazos and the Colorado 

 Kivers. 



Raldea striatula Linn. Two specimens were taken near Dallas by J. 

 Boll, and one by Mr. Schmit, near Houston. 



Virginia elegans Kenn. From Dallas and Helotes. The V. valerice 

 Bd. and Gird, is the Carpliopliis liarperti of Dum6ril and Bibron, de- 

 scribed a short time previously. 



Contia episcopa Kenn. This is a characteristic species of "Western 

 Texas. It is common west of Fort Worth to Fort Concho and about 

 Helotes in the south. It exhibits a great range of color-variation, so 

 that it is now evident that the (J. isozona must be reckoned as one of its 

 varieties. Thus its range extends to Utah and Arizona. 



The general characters of the species are as follows: Scales in fifteen
