like that. It was said to be rather common near Puerto

Liosaurus Belli Gray. 

 (Boulenger, Cat. of Liz. II, p. 124. 1885.) 



One specimen from Puerto Madryn, Patagonia, 6 /u 1895, 

 where it was not uncommon in sandy places. 



Diplolsemus Darwini Gray. 

 (Boulenger, Cat. of Liz. II, p. 126. 1885.) 



There are three specimens of this lizard in the collection. 



1. Cerro Toro, South Patagonia, 25 /i2 1896. 



2. Santa Cruz, Patagonia, 14 /ii 1895, in sandy places.

 captain. 



These three specimens vary considerably in colour, N:o 1 and 

 3 are large specimens, 95 and 105 mm. from the tip of the 

 snout to the vent. In N:o 1 the black cross bands are very 

 broad and festooned, in N:o 3 they are narrow and nearly of 

 the same width; in N:o 1 the upper surface of the head has 

 large and dark markings, in N:o 3 some small dark spöts only. 

 N:o 1 agrees most with Diplolcemus Darwini Bell, described in 

 >,The Zoology of the voyage of H. M. S. Beagle», p. 20, Vol. 

 III, London 1842, plate X. N:o 3 agrees with Diplolcemus Bibroni 

 Bell, in the same work, p. 21, plate XI. In the specimen N:o 2, 

 which is a small one, 49 mm. between the tip of the snout and 

 the vent, the cross bands are broken up on the back and appear 

 as two rows falciform dark spöts with the concave hinder margin 

 edged with yellowish white. The head without dark markings.
