*4. Eny alius Iheringii, sp. n. 



Distinguished from E. catenatus (Wied) in the following 

 points : — Nostril nearly equally distant from the orbit and 

 the tip of the snout. The scales on the vertebral region rela- 

 tively larger, subrhomboidal, flat, distinctly keeled. Limbs 

 shorter ; tibia shorter than the head ; the adpressed hind limb 

 reaches the anterior boixler of the orbit in the male, the angle 

 of the mouth in the female. Purplish brown above, the male 

 uniform, the female with an alternating series of black spots 

 on the vertebral region and, on each side from nape to base of 

 tail, a broad yellow band ; lower surfaces brownish or 

 purplish.

This species is closely allied to L. pectinatus (D. & B.), 

 which it resembles strikingly in coloration. It is, however, 

 easily distinguished by the longer digits, the nearly equal 

 length of the third and fourth fingers, and the strongly keeled 

 ventral scales. The species was originally described from 

 Uruguay, whence the Natural-History Museum has also 

 received a specimen, hitherto confounded with L. pectinatus. 

 A fine specimen from near the coast was sent by Dr. v. 

 Ihering. 



*6. Liolamius occipitalis, sp. n. 



Near L. multimaculatus (D. &B.). Snout short, rounded ; 

 nostril superior, above the canthus rostralis ; tympanum 

 hardly as large as the eye- opening, without denticulation 

 anteriorly ; upper head-scales smooth ; an enlarged oblique
