A TARANTULA IN CAPTIVITY 
189 
from its place to allow the body of the individual to leave the 
exuvia. After this moult the specimen measured 55 mm. from the 
distal end of the chelicera to the tip of the abdomen and 24 mm. 
at the widest portion of the cephalothorax. Feeding was re- 
sumed until September 27, when it became dormant. 
On several occasions the tarantula was taken from its cage 
and given opportunity to move about in order to observe its 
movements. It would invariably seek a dark place as under a 
leaf or behind an object, which demonstrated that it was nega- 
tive phototrophic. 
The possibility of an escaped tarantula finding a suitable place 
to spend the winter in the latitude of Iowa is rather remote. An 
unexpected freeze during the second week of November, 1921, 
unfortunately caused the death of this individual.
