208 SAURIA. 



they constitute twelve longitudinal series, or else six pairs, smallest 

 under the neck ; they likewise diminish in size laterally, and, on the 

 preanal region, from subquadrangular, they assume a more rounded 

 aspect, though not much diminished in size; in fact, they are as large 

 here as on the pectoral region. 



The anterior limbs are very slender and short ; when they are 

 stretched towards the head, the extremities of the fingers are made to 

 reach the angle of the mouth; their insertion takes place in the granu- 

 lar area, contiguous, by their inferior surface, to the pectoro-abdominal 

 shields. The upper and anterior surface of both the forearm and arm 

 is covered with well-developed, polygonal, and subnodulous scales or 

 plates, extending somewhat under the elbow, where they diminish con- 

 siderably in size. On the inferior and posterior surfaces of the same 

 organs, we observe very small scales, assuming a granular appearance 

 towards the shoulder. The palm of the hand is minutely scaly. The 

 fingers, five in number, are plaited above and below to the very root 

 of the nails. The first or inner finger is the smallest ; the next in 

 length is the outermost or fifth; then the second, which is but slightly 

 longer than the fifth; the third and fourth are the longest, and nearly 

 equal in length, though the third stretches a little beyond the fourth. 

 The nails are subconical, compressed, and slightly curved. The poste- 

 rior limbs are somewhat longer and stouter than the anterior ones, and 

 similarly inserted in the granular zone. The thigh is covered ante- 

 riorly and superiorly with keeled, and beneath with smooth scales, 

 whil.-t on its posterior surface, the scales are very minute and granular 

 in their appearance. The scales on the upper and anterior aspects of 

 the leg proper are likewise keeled, though less conspicuously than on 

 the thigh; they are smooth beneath and posteriorly, where they simply 

 diminish in size without becoming granular. The feet have the same 

 general structure as the hands ; the sole is covered with small, elon- 

 gated, and somewhat raised scales. The inferior surface of the toes 

 has a verticillated appearance, arising from the disposition of the scales 

 or plates, which are slightly nodulous, as well as under the fingers ; a 

 series of plates is observed on their upper surface. The first toe is the 

 shortest ; the second is the next in length ; the third and fifth are 

 nearly equal, whilst the fourth is the longest. The nails are subconi- 

 cal, compressed at the base, curved, and acute. The tail appears to 

 be long and slender, judging of it from the portion preserved on the 

 specimen figured, and which is almost as long as the body and head
