OBSERV. The genus which we here establish, is to include some 

 small Saurians, Lygosoms-like in their general aspect, or rather dimi 1 - 

 nutive Cyclodi, to which they bear close affinities. Its representatives 

 appear to be confined to the Austral lands, whence the so far known 

 species have been obtained. 



Besides the two species brought home by the Exploring Expedition, 

 there is a third, figured on Plate iv, fig. 1, of the Atlas accompany- 

 ing the " Voyage au Pole Sud et dans 1'Oceanie, sur les corvettes 

 1'Astrolabe et la Zelee," under the command of Captain Dumont- 

 d'Urville, and known as " Lygosoma crassicaudum, HOMBR. & JACQ."

Its very stout tail distinguishes it at once from those described below, 

 though apparently more allied to H. fasciolaris than to H. undo-so.. Its 

 thick and obtuse snout is quite peculiar to it, enabling us at once to 

 distinguish it from its congeners.
