erythronotus, but without red dorsal band. Both readily 

 distinguished from Spelcrpes bilineatus, the only local Sala- 

 mander resembling them in form, by comparison of ventral 

 surface, which in the latter is immaculate. 



The eggs are laid in damp moss and under bark of de- 

 cayed trees. Found October 25. The young lose their 

 gills about three or four days after hatching. It is never 

 aquatic, even in the larval stage.* 



Very common in woods under logs and stones. Several 

 captured as early as April 17, six under one stone. 



Prof. Cope says he can find no differences in structure, 

 proportions or general character between P. cinereus and 

 P. erythronotus, but believes the varieties to be very per- 

 manent. On May 14 I found seven pairs, each pair under 

 a separate stone, and, in each instance, one with red back 

 and one with brown. As males and females of both kinds 

 are found, this has no present significance, but is mentioned 

 for comparison. 



Plethodon glutinosus Green. 

 Blue-spotted Salamander. 



This is the Salamandra glntinosa of De Kay. 



Whole skin covered with a milky secretion or mucus. 

 Glossy black with white spots thickly scattered, some form- 

 ing confluent blotches on the sides ; generally a large 

 number at sides of neck, and one to several on throat; also 

 spots on the legs. Gular fold distinct ; in alcohol shows as 

 a white band. Color below bluish to lead color. Body 

 stout. Fore legs slender ; hinder comparatively stout. 

 Length four to six inches, of which tail is about two or 

 more. Costal folds, 14. 



Found at Fort Lee, generally between rocks or ledges 

 in the woods, and under logs near by. Always terrestrial. f
