liua, aud Louisiana. It is not yet known from Florida or Texas. A sin- 

 gle specimen in the National Museum was taken in the Susquehanna 

 River, Peuusylvauia. 



The "hellbender" is entirely aquatic in its habits, and is frequently 

 taken by fishermen on their hooks. It is very tenacious of life, and is 

 perfectly harmless. Its larval period must be of brief duration, since 

 it has not been yet observed. The eggs are rather large, and are at- 

 tached by two strong suspensors at opposite poles.

There is some variation in specimens in the relative distance of one 

 nostril from the other and from the eye. In some specimens these dis- 

 tances are identical; in others the former is somewhat less than the 

 latter, and the same measureuient, usually one-half the width between 

 the eyes, may enter it 2.25 times. 



A local variety is seen in three si)ecimens (iSTo, 7005) from Abbeville, 

 S. 0. These are a light brown, much resembling the G.fuscus, but are 

 spotted with a darker brown. The double papillae are not visible on 

 the superior surface of the head, and are faintly marked on the inferior 

 aspect. The rows of pores are, however, as in C. allegJieniensis, as are 

 the tongue and internal nares. The digits are all more slender, and the 

 dermal ala on the external toe and that of the elbow are much reduced. 



Besides the generic character, the following ditferences may be ob- 

 served on, comparison of this species with the 3Iegalohatrachns ma.vimus 

 of Asia. In the latter the tongue is not free, but is sessile, and with- 

 out plicaj; head with rows of oltuse tubercles; sides and limbs without 

 dermal folds.
