scaly. Auricular aperture simple. Limbs four, weak, far apart ; 

 five fingers and five toes, rather short, subcylindrical, and clawed ; 

 their under surface transversely plated, smooth. Palms and soles 

 coarsely granular or subtubercular. Tail moderate.

OBSERV. The species which constitute the present genus may truly 

 be termed diminutive Cyclodi, for, their affinities with the latter are 

 most intimate. They differ therefrom chiefly by the subquadrangular 

 shape of their body, their conical teeth, their auricular aperture, simple, 

 instead of being denticulated anteriorly. Finally, the number of lon- 

 gitudinal series of scales around the body are much less numerous than 

 in Cydodus, as understood by John Edward Gray, that is, not includ- 

 ing Cyclodiis casuarinae. 



It appears to us that Lygosoma temmincldi, DUM. & BIBR. (Erpe"t. gen. 

 V, 1839, 727), will prove congeneric with the species described below.

SPEC. CHAR. Body rather long, protected by twenty-six longitudinal 

 series of scales. Snout short. Suborbital chain of plates complete ; 

 no labials entering into the orbit. Auricular aperture small. Two 



, middle preanal scales larger than the rest. Limbs quite small.
