This is one of the most marked species of Kortli Americau salaman- 

 ders. The large temporal muscles give tlie head a swollen outline be- 

 hind, and separate the derma from the cranium. The latter adheres to 

 the top of the prominent muzzle. The fissure of the mouth is sinuate, 

 most strongly so in adult specimens. On the whole, the physiognomy 

 is not unlike that of the snapping tortoise. I have little doubt that it 

 is more capable of inflicting a bite than any other of the American 

 Urodela. Its food does not appear to differ much from that of other 

 salamanders; in the stomach of one I found ants, in another three or 

 four species of beetles, among them an entire Cocciuella.

This is a smaller and more slender species than the last, not being 

 very different in proportions from PletJiodon intermedins, but with a 

 broader and more flattened head. 



The head is an elongate oval, slightly truncate in front. The nostrils 

 are an tero lateral, and with a delicate groove connecting with the com- 

 missure of the month. Canthus rostralis not marked. The muzzle is 

 as long as the fissure of the eye, while the length of the commissure of 

 the mouth (diagonal line) is equal to the width of the head at the 

 rictus. The tongue is largely free, the posterior portion rather 

 narrowly. The inner nares are nearer together than the outer. The 

 vomerine teeth commence behint^ the nares, and form a single series of 

 eight on a ridge, which is gently arched backwards on the median line. 

 The parasphenoid patch does not extend quite forward to the mid- 

 dle of the orbits; it is much flatter and wider anteriorly than in 

 A. luguhris, and contains opposite the posterior margin of the orbits ten 

 longitudinal series of teeth, those of adjacent rows alternating.
