For description of this interesting lizard, vide Stansbury's Report of Ex- 

 pedition to the Great Salt Lake, page 346. It is chronicled as -inhabiting 

 the valley of the Great Salt Lake, but was not met with by our party in 

 the locality noted, being seen only on the western border of the House 

 range of mountains, which form the western limit of the valley in extreme 

 Eastern Nevada.
