abandoned animal dens. During the summer and fall the salaman- 

 der leaves its den only at night, when it forages for food. In the 

 fall these forays seem to lead it further afield and it often falls into 

 excavations and window holes. I once had forty-nine brought from 

 a home situated in an oak-hickory woods. I know of two that sur- 

 vived a winter in separate window holes. 



As a rule the young salamander hatches from eggs laid in a more 

 or less temporary pond. I find it frequently associated with the 

 Newt. It leaves its pond in late August. 



Breeding Habits. During the first warm rainy nights in March 

 the Tiger Salamanders gather at their breeding ponds. Often an 

 appreciable amount of ice still remains on ponds located in the 

 woods. The breeding activities are known from watching pairs 

 placed in an aquarium lighted by photographer's red lights. The 

 male butts the female vigorously in the region of her vent. Finally 

 he stalks ahead, rubs his vent on the bottom, and deposits a sper- 

 matophore. During the emission of the spermatophore his feet are 

 raised off the bottom. The tail is raised at right angles to the body 

 and undulated. At the same time his body moves convulsively. 

 Meanwhile the interested female has been resting with her muzzle 

 close to the vent of the male. When he moves on she follows him 

 until her vent is over the spermatophore. She then repeats the 

 motions of the male as she encloses the spermatophore with her 

 vent. Apparently the female shows little interest in a spermato- 

 phore not deposited during courtship. 



In late March or in early April the female deposits some fifty 

 eggs, which are to be found as masses attached to submerged twigs 

 or vegetation in about 30 cm. (i foot) of water. Each egg is some 

 3 mm. in diameter. One end of the egg (the animal pole) is 

 brown, and the opposite half (the vegetable pole) is cream colored. 

 Around each freshly laid egg there are three distinct envelopes of 

 clear jelly. A fourth layer forms a mass that envelopes all the eggs 

 and holds them to their support. The eggs probably hatch in about 

 three weeks. 



Food. This species has an appetite that belies its daytime ap- 

 pearance of sluggishness. The adult will eat earthworms, various
