5. EULAEMUS AFFINIS, Grd.

 small and numerous. Temporal scales subhexagonal, smooth, rather 

 convex, and but slightly imbricated. Auricular aperture oval, granu- 

 lar in front. Dorsal scales rather larger than the lateral ones, which 

 are smooth ; abdominal scales rhomboid, smooth. Posterior aspect 

 of thighs granular, with a patch of scales near the tail. 



Syn. — Proctotretus fiizingerii, Bell, Zool. Voy. Beagle, Y, 1843, 11. PL v, fig. 1.

Eulaemus affinis, GrRD. in Proc. Acad. Nat. Sci. Philad. November, 1857, 198. 



Observ. — Not amongst the reptiles collected by the U. S. Exploring 

 Expedition. The study of its characters, in the published records, has 

 convinced us that it was distinct from the Chilian species. 



Log. — Port Desire and Santa Cruz, Patagonia.

 Supralabials smaller than the labials. Temporal scales moderate,

 smooth and larger ; abdominal scales somewhat convex, generally 

 entire posteriorly. Posterior aspect of thighs wholly granular.
