14. GERRHONOTUS 455 



"Consequently, one evening, I settled down to work in 

 one corner of the laboratory behind the screen. Very shortly, 

 scarcely hearing any noise, but feeling that something was 

 under way on the silkworm tables, I quietly moved my 

 position to see what was going on. And there I saw, what 

 I had least expected, a large lizard Gerrhonotus, quietly 

 beginning to make away with a soft juicy silkworm. 



"I was so intent on clapping a cage over the creature to 

 capture him that I failed to observe his method of devour- 

 ing his prey."
