but separate from each other, and are laid not in the 

 water in spring, but under dead logs in the beds of 

 dried-up pools in October. The transformation takes 

 place about May, the larvae reaching a length of at 

 least 2% inches. 



Engelhardt, in Copeia 37, November, 1916, re- 

 ferring to Long Island (where Pike worked), states 

 that he got larvae 1% to l 1 /^ inches long on April 7. 

 He argues that these could not have come from eggs 

 laid that spring as the pools were ice covered until 

 April. The hind legs of these larvae appeared on 

 April 18. Other larvae collected in May measured 

 2T/2 inches in length. 



' Finally on September 20, 1916, near Mt. Ver- 

 non, Va., I got 7 adults, male and female, under one 

 log. The females were larger than the males, and 

 had a pronounced tendency for the cross-bands to 

 break up into 2 longitudinal stripes (the same tend- 

 ency has been noticed in females of opacum from else- 

 where) . The males had the lips of the cloaca everted 

 and swollen. 



Some of the females laid eggs in the collecting 

 bucket. The next day I got several others near there, 

 including a female in her nest with over 100 eggs. 

 The eggs were entirely unconnected and were rather 

 dusty. I kept the eggs from the several females in 

 damp debris. Developments proceeded somewhat 

 slowly until on October 2, they were put into 3 crys- 

 tallizing dishes containing, (1) sand; (2) sand and 

 water, the eggs being placed out of water; (3) water. 



Those in the water began to hatch on October 

 15. When born they had fore-limb buds and bal- 

 ancers. Those eggs kept in dry sand until October 

 15, and put in water on that date hatched in 24 hours. 



Eggs kept until November in sand saturated 

 with water, did not hatch, but when put into water, 

 hatched in 24 hours. Thus the entire egg must be 

 surrounded with water for it to hatch. There is ap- 

 parent here a very delicate adjustment to Coastal 

 Plain conditions of flood and drouth.
