COP EI A 31 



This species was the only salamander observed 

 in the vicinity and was found in a small stream near 

 a lumber mill. The rocks about Flagstaff are red 

 volcanic larva. 



Both the gilled and air breathing forms were 

 found together in the water, some of the specimens 

 reaching a length of about six inches. The color of 

 the gilled forms was olive brown with dark irregular 

 spots on the back, sides, belly and tail fin. The air 

 breathing forms were darker and less spotted. This 

 color varied somewhat with individuals and with the 

 surrounding temperature, the specimens becoming 

 lighter as the air or water became warmer. The gills 

 were not as fully developed as in many specimens 

 which the writer has seen in captivity, and the caudal 

 fin was not as broad. Neither did it extend up the 

 back as far. 



Several boys in the vicinity reported finding their 

 eggs during the month of June, while the writer was 

 absent, and secured several immature gilled specimens 

 about two inches in length. 



No land forms were found out of the water, al- 

 though they may have occurred there. But as the 

 ground is exceedingly dry in this vicinity the writer 

 doubts whether this species is found far from water 

 at this locality. 



These salamanders were quite abundant in cer- 

 tain pools of the stream, as many as nine being count- 

 ed in a pool about seven feet in diameter and one foot 

 deep. They were very active and difficult to capture 

 by hand, and generally darted to cover under some 

 submerged plank or stone. 



Several specimens of the land form, which the 

 writer collected, are now thriving in shallow water at 

 the Bronx Zoological Park. They feed greedily and 

 will even snap harmlessly at one's finger.
