site shore, it stopped to rest a second or so, floating 

 a short distance down stream, when it resumed its 

 movements towards the bank. Close to the bank it 

 stopped paddling, floated gently up on the mud, and 

 after a few moments' rest, crawled slowly out on the 

 muddy shore, stopping again for a rest. Five or ten 

 minutes later it was still resting in the sun. Never 

 having seen the box tortoise swim before, this note is 

 offered as possibly of interest.

NUMBER OF YOUNG PRODUCED BY 

 CERTAIN SNAKES. 



I quote the following records from my notes, 

 trusting that they may be of some interest. All the 

 specimens referred to were taken in Nelson County, 

 Va.: 



Natrioc septemvittata. August 31st, 1914. Five 

 young. 



Natrioc sipedon. I have never observed over 40 

 young, but have three records of this number, one 

 each of 36, 33, and 25. Dates of birth, August 12th- 

 October 12th. 



Heterodon plat y rhinos. August 16th, 1913. A 

 nest of 34 eggs ploughed up in a field. They hatched 

 August 23-27. 



Agkistrodon contortruc. September 1, 1913, 7 



young. These young snakes, though born alive, had 



well developed egg- teeth, which were not present in 



the young of either Natrioc. They were quite evident 



in the young of Heterodon. ■--, -„ ^\
