46 Mr. A. W. E. O'Shaughnessy on 



recognize as belonging to this species — a still longer and 

 slenderer one than G. tessellatus, and having the tail of ex- 

 cessive length, but agreeing with the latter in the arrangement 

 of the supranasals.

The young specimen figured by Baird seems to have only 

 one pair of narrow oblique supranasals.

The type of this species in the British Museum is in a rather 

 bad state. It agrees with the lengthened description of G. 

 multifasciatus in the ' Erpdtologie Ge"ne"rale.' Two pairs of 

 narrow supranasals, without accessory plate between. Tail 

 more than twice the length of body and head together ; fifty 

 transverse series of scales from occiput to commencement of 

 tail. 



B. Head and body stouter ; tail of moderate length. 



G. Wiegmanni, Gray, Catal. of Lizards, 1845, p. 54. 



Type in the British Museum. I do not find any allusion to 

 this species by succeeding writers. The arrangement of the 

 plates of the head is the same as that in the figures of Elgaria
