later and were evidently eaten. On March 23 one of the lizards 



tried repeatedly to catch one of the five crickets introduced, but 

 failed, and finally gave up the chase, even refusing the insect 

 when it was held before him in the forceps. The lizards were 

 seen to catch and eat crickets on the following days : April 1 3 

 (two); April 20, April 27 (two), and on several occasions spec- 

 imens that were introduced in the evening had disappeared by 

 the following morning. Indeed, crickets seem to form the prin- 

 cipal food of these lizards.

SCORPIONS.
