slightly granular, the rest of the venter is conspicuously and roughly 

 granular and dull yellow in color, with the under side of the femur a 

 deeper yellow, and the axilla bright yellow with a wash of same along 

 the sides. The tubercles under the joints of feet and hands are promi- 

 nent and pointed. 



"Male with two external vocal vesicles, each being situated near 

 the angle of the mouth; during the breeding-season the inner side of 

 the first finger covered with blackish rugosities. From snout to vent 

 75 millim." (Boulenger, 1882, pp. 368, 369). 



Structure: Tongue subcircular; head broader than long in adults; 

 casque emarginate behind; snout rounded, contained two times in 

 head to tympanum; pollex rudiment not free projecting; disks con- 

 spicuous; no interocular bar; upper eyelid small; tympanum distinct, 

 1/2-3/4 diameter of eye. 



Notes: Our experience is limited to one live frog sent us the spring 

 of 1932, and two specimens given us several years ago by Dr. T. 

 Barbour. 



In 1 93 1, Dr. Barbour adds it to the fauna of the United States. 

 Of this extension he speaks thus: 



"Another Introduced Frog in North America. — Several years 

 ago, on a damp May morning in Key West, after a heavy shower, I 

 heard the unmistakable call of Hyla septentrionalis. This sound is 

 like the jerky pulling of a rope through an unoiled pulley and is very 

 characteristic. I hurried on my journey and thought nothing more of 

 the matter until my kind correspondent, Mr. A. G. Elbon, sent me a 

 jar of amphibia taken at Key West but a few days ago. There were, 

 to my surprise, three superb specimens of Hyla septentrionalis 

 amongst the lot in the jar. . . . 



"Mr. Elbon's letter follows. I had asked him what he knew about 

 the occurrence of these frogs. 



"I first met with septentrionalis here at Key W 7 est about three 

 years ago. That was when I first came here to live. The old people 

 here seem to remember these big frogs in their gutter pipes since they 

 were children. I know of no one here with enough knowledge of 

 natural history to give me any very dependable information. 



" 'The only place I have found these frogs is in the pipes leading 

 from the gutters to the cisterns. 



" 'Last summer these and the smaller frogs were so numerous as to 

 almost be a pest. I was forced to put a screen over the ends of an 

 eight foot pipe leading from the down spout to a rain water tank and 

 in so doing took twelve frogs from the pipe. Five of which were 

 septentrionalis. This year frogs of all kinds are very scarce. I would 

 call this big frog common here. I have found it feeding almost alto- 

 gether on the smaller frogs. . .
