187-1.] MR. W. T. BLANFORD ON TWO NEW LIZARDS. 659 



Scales. Head covered above with convex scales, largest on the 

 snout and occiput, and on the forehead between the eyes. Canthus 

 rostralis rounded ; nostrils lateral, oval, rather large, each in the 

 middle of a single plate below the canthus. Rostral enlarged ; 

 mental smaller than the rostral ; laterals scarcely larger than the 

 neighbouring scales ; posterior upper labials triangular, all the rest 

 square. Chin, except near the lower labials, covered with very 

 small convex scales ; scales of the neck equally small, subconical or 

 mucronate, those 6f the lower surface in transverse rows. Sides of 

 the neck with irregular longitudinal folds, bearing enlarged tuber- 

 cular pointed scales ; there are also folds below the neck, but they 

 are not ornamented with tubercles. Scales of the back and sides all 

 small, submucronate, with the points compressed and directed back- 

 wards, in well-marked transverse rows except near the middle line of 

 the back ; no enlarged scales on the sides. Abdominal scales 

 rhomboidal, a little longer than those of the back, arranged in 

 transverse series. Scales of anterior portion of the fore limb like 

 those of the abdomen, those on the posterior surface the size of the 

 back scales ; a few slightly enlarged scales on the outer surface of 

 the forearm. In the hind limb, the scales are larger on the inner, 

 smaller on the outer surface ; a row of large conical tubercles passes 

 down the front of the tarsus, and large spinose tubercles are scattered 

 over its outer surface — a few, smaller in size, occurring on the pos- 

 terior portion of the thigh. Feet and toes covered beneath with 

 keeled scales, the keels longitudinal on the soles of the fore feet, 

 transverse on those of the hind feet. In the largest specimen, a 

 male, there are eighteen femoral pores on one side, twenty on the 

 other ; but they are somewhat irregular ; in a younger specimen 

 there are fourteen beneath each thigh, the two series coming close 

 together in the prseanal region. Tail, when perfect, consisting of 

 about twenty-three or twenty-four rings, the upper and lateral 

 portion of each ring consisting of large spines, the points directed 

 backwards ; the lower portion, except towards the tip, is covered by 

 rings of smaller nearly flat scales diminishing in size towards the 

 base of the tail. 



Colour. Olive-grey, with small rather indistinct darker spots on 

 the back ; lower parts and tail rather paler. 



Intestinal canal elongate. In a specimen measuring altogether 

 17 inches in length, of which the tail is 7, the whole length of the 

 intestinal tract from the cardiac end of the stomach to the anus is 

 28 inches, the large intestines measuring 8 inches*. 



The largest specimen obtained measures 20*5 inches from nose to 

 tip of tail, tail from anus 8"5, head 2, fore limb nearly 5, third toe 

 of fore foot from the division between the third and fourth toes to 

 the end of the claw 1*1, hind limb 6*1, third toe of hind foot T3. 



This species was found inhabiting the neighbourhood of Basrah 



* In a specimen of Centrotrachelus asmussi, Strauch, 18 inches long, the 

 intestinal tract measures 40 inches. In Agama, Stellio, and Phrynocephalus I 

 find the intestinal tract always shorter than the body and tail : thus it is 7 inches 

 long in an individual of Agama agilis measuring 10 inches.
