roimdod 1 )y minute tubercles ; scales of muzzle tubercular. Labials less 

 elongate, five oblique, one Hat; femoral pores lii-13; no blue spots on the 

 sides; transverse blue spots on the inferior side of the tail. Color light 

 brown, with six pairs of transverse dark-brown bars between the scapu- 

 lar region and groin, which extend downward and backward on the 

 abdomen. Their posterior border is serrate oi- digitate, and edged with 

 yellowish, producing a variegated pattern. The inner part of the spots 

 is frequently cut entirely off. The spots are continned on the ui)per 

 side of the tail, and there are six irregular longitudinal brown bars on 

 the neck. A brown band across supraorbital regions, and spot on upi)er 

 surface of muzzle. Limbs brown cross-banded. A pale band on infe- 

 rior part of side, which is crossed by the ends of the lateral spots. 

 Below this are five or six small dark spots, sometimes obsolete. Total 

 length, 99 mm.; to collar, 15 mm.; to vent, 56 mm. This is a short- 

 legged species allied to the H. maculata, but with longer tail and very 

 different coloration. As compared with the variety of H. maculata, 

 above described, the labial scuta are shorter and less oblique, resem- 

 bling more nearly those of H. te.vana. In coloration it differs from the 

 H. maculata in a point not above mentioned. The dorsal ground color 

 is everywhere the same, a rich yellowish brown. In the H. maculata 

 the median dorsal region is paler, and the sides of the back are of a 

 dark shade, which connects the spots as by a wide band. 



The most northern locality for the IIolbrooMa lacerata with which I 

 am acquainted is in Erath County, west of the Upper Brazos. Mr. Boll 

 found it rather abundantly there and in Comanche County. Southward 

 it has been found by Mr. Marnock on the Guadalupe Eiver in Kendall 

 or Comal County. It thus belongs to the first plateau fauna, and is not 

 widely distributed. 



The specimens above mentioned do not exhibit lateral spots, but they 

 are present on the following specimens, which have been received by 

 the Smithsonian Institution : 



Holhrookia maculata lacerata Cope, 



HOLBROOKIA MACULATA MACULATA Girard. 



In this subspecies the body is moderately stout and depressed; 

 much more so in the females. The head is broad and short, as wide as 

 long, pointed anteriorly to the broad and rounded muzzle. The lateral 

 outline of the head is very convex posteriorly, then slopes from the 

 middle to the head nearly in a straight line to the line of the mouth.
