 Clay Co., Ark., where it was collected by Dr. Eugene S. 

 Meek of the Field Museum of Natural History, and, no 

 doubt, will eventually be found in the Sunken-lands of 

 Missouri. 



Habits. — Colonel Nicholas Pike in Bulletin No. 7 of 

 the American Museum of Natural History, gives a 

 very able life history of this toad, from which I quote the 

 following : — ' ' The harmless little creature is still not un- 

 common, if you only knoiv ivhere to find it. There lies the 

 difficulty — so few do know — and, excepting some natural-

 It must of course be hunted for in secluded places, and
