neer seen such a splendid lizard except my Diploglossus 

 resplendent from Bolivia. 



A few days after our Upper Jesusito camp was made we 

 began to fell trees to let in sunlight and breeze. As it turned 

 out, there was no breeze and the sun was almost constantly 

 obscured by rain clouds. One tree came down with a crash 

 and brought with it a living and uninjured Corythophanes cris- 

 tahis. The interesting point in connection with this capture 

 was the fact that we chanced to keep the lizard alive long 

 enough to find that its actions were singularly chamaeleon-like. 



It was sluggish and deliberate in its movements, and when 

 angered it reared upright, flattened its body vertically, and 

 bent down its head. Its mouth meanwhile was opened widely 

 in a way that recalled at once captive and angry African 

 Chamaeleons. That the very peculiar superficial similarity of 

 appearance should be accompanied by such similar sluggish 

 movements and curious attitudes is most noteworthy and 

 almost incredible when the protean zoologic gap between the 

 two genera is considered. 



In a few places where the forest roof leaked spots of sun- 

 light the ground did dry out and the great, curly, new-fallen 

 leaves made noisy walking. In these little dried out spaces 

 we found some tiny lizards. They crept swiftly and stealthily 

 over the big dead leaves, and when the sun was hidden, as it 

 often was because of the frequent showers, these little lizards 

 hid at once, to reappear when their mouldy abode became dry 

 again. They were not easy to catch, and when one was finally 

 in the fingers a decent specimen was by no means assured, 

 for their skin tore like wet tissue paper and their struggles 

 usually left them sadly unfrocked. 



These, as other slim-toed gekkos or Eublepharids, as they 

 once were called, are far more agile than their allies with
