The attribute of bipedal locomotion is possessed by the 



teguexin. That this singular method of progression was an 



accomplishment possessed b)' one of the larger tropical 



American lizards was first reported to the writer from 



Trinidad. Some species of iguana was, in the first instance, 



anticipated to be the acrobatic performer. Several ex- 

 amples of this famil)' group were accordingly put throu.gh 



their paces at the Zoo, to ascertain if the\' could lay claim 



to the distinction. None of the iguanas available, however, 



rose (on their hind legs) to the occasion, and it was only 



on experimenting, as a lici'iiicrc rcssourcc, with the teguexin 



that a successful demonstration was accomplished. This 



lizard was found, in fact, to run bipedalh' more freely and persistentl}-, when sufficient space 



was allotted it, than the Agamas. It seems singular that this bipedal power of locomotion 



should have so long remained undisco\'ercd, and \'et is possessed by lizards which ha\e for a 



number of years been the denizens of many 

 zoological gardens and other menageries. 

 The fact that a comparatively lai'ge le\'el area 

 is a sine t]ua iioii for the exhibition of this 

 phenomenon aftbrds no doubt the explanation 

 of this anomal}' ; but the anomah' itself at the 

 same time serves to accentuate the desirability, 

 in the inteix-sts of both science and the animals' 

 comfort, that exists for providing them in cap- 

 tivit_\'with a more liberal and reasonably sufficient 

 space for their indulgence in those methods of 

 locomotion that are natural to them in their 

 native land. 



The Greaved Lizard Family includes some- 

 what over one hundred species. While the 

 majority agree with the teguexin in the pos- 

 rdics session of well-developed limbs, there are a few
