40 ON THE ZOOLOGICAL POSITION OF TEXAS. 



represented by three large adult individuals of very light colors. They 

 differ remarkably in the scuta of the nose. In one the frontonasals 

 and supranasals are in contact; in the other two they are separated by 

 the prefrenals. In the former there is one prefrenal on both sides, and a 

 postnasal on one side. In No. 2 there is a postnasal on each side, and two 

 prefrenals, one above the other, on one side only. In No. 3 there is 

 no postnasal plate; the prefrenal is in contact above with the inter- 

 frontonasal. On one side of the head it is divided by a horizontal fis- 

 sure into two scuta, one above the other; the other side is undivided. 

 The hinder leg measures one-third the distance from its base to the end 

 of the muzzle. When extended along the side, the fore and hinder limbs 

 just touch the extremities of each other's claws. The second and fifth 

 posterior toes are of equal length. Color pale ashen, with a bluish or 

 greenish tinge. The external edges of the scales of the second row from 

 the median line are brown, forming a longitudinal line on each side. In 

 the same way the edges of the scales of the oblique lateral rows of scales 

 are brown. These oblique brown lines are each six or seven scales long; 

 anteriorly they become more longitudinal, two parallel lines running 

 backwards from above the superior border of the ear. Superior labial 

 plates brown edged. Scales of posterior faces of limbs brown edged. 

 Length to vent, m. .101; length to axilla, .038; length to meatus of ear, 

 .020; length of hind leg, .032. 



No. 1 is colored like No. 3, omitting the dorsal lines; No. 2 is like No. 

 1, except that the lateral brown borders unite into a wide, loose band. 



Eumeces epijyleurotus sp. nov. Through the kindness of Professor Baird 

 I was able to inspect three specimens of this species which are preserved 

 in the Museum of the Smithsonian Institution. They are from the north- 

 ern boundary of Texas and from Nebraska, at Fort Kearney. 



The species belongs to the group of the E. fasciatiis, having a small 

 postnasal in front of the base of the usual larger one, and agrees with 

 the U. leptogrammus Bd. in having but 24 rows of scales. The post- 

 nasal reaches the rather transverse interfrontonasal. The limbs are not 

 very short, being separated when applied to the side by a space less 

 than the length of the forefoot. The coloration is as follows : The median 

 dorsal pale band covers only the adjacent halves of the two median rows 

 of scales. A black band bordering it occupies the remaining half of the 

 row, with the adjacent half of the next row. The remaining half of the 

 next row is occupied by a pale band. A black line passes along the 

 adjacent edge of the nest row, whose middle is white. The external
