elude it in this list on the authority of Dr. Eugene S. 

 Meek of the Field Museum of Natural History, Chicago, 

 HI., who collected some at Greenway, Clay Co., Arkansas. 

 Clay County adjoins Dunklin Co., Mo., to the east, and no 

 doubt this species will eventually be found in Missouri. 



Hahits. — The Squirrel Frog lives in both low and tall 

 vegetation. It may be found on the vines and shrubs of 

 the garden, or on the margins of lakes and rivers, or even 

 in the trees of these localities. It conceals itself under the 

 decaying bark of trees or under dead logs. My friend, 

 the late Mr. Louis Schoelch, when collecting beetles in 

 1891, near Mobile, Ala., caught a number of these frogs, 

 while mowing bushes with his net to secure beetles. He 

 presented them to me, and they are still in my collection.

 patches lying between, or a little behind, the choanae. Eyes large and 

 protruding. Tympanic disk about two-thirds the diameter of the eye, 

 with moderate fold of skin above it. Body stout and clumsy; the 

 breast crossed by a broad fold of skin. Extending the hind leg along 

 the side, the heel reaches to the back of the orbit. Anterior limbs 

 short, stout, fingers and toes broad, dilated into disks; the one on the 

 third finger being nearly equal to the tympanum; the disk of the inner 

 finger is smaller than the rest; the first finger opposed to the rest. 

 The web is more extended than in other species of the United States. 

 Toes webbed to near the tips. 



Upper surface of the body with numerous smooth warts; belly and 

 under surface of the thighs granulate, the band across the breast less 

 so. Subarticular tubercles moderate. A large tubercle on the base of 

 the pole. Another one on the base of the first toe. A very distinct 

 fold along the inner side of the tarsus. Males furnished with a large 

 gular sac, which opens on each side under the tongue. (Hay.)
