5. Rana sylvatica LeConte. Wood Frog. The single spec- 

 imen of this species in the collection was taken at Searchmont, 

 Ontario, Canada, August S, 1906. In this specimen the heel 

 just reaches the anterior border of the orbit and the leg bars are 

 very faint, two points in the direction of Rana cantabrigensis. 

 However, it has as well developed an outer metatarsal tubercle 

 as most specimens of Rana sylvatica, and the webbing on the 

 feet and general coloration is that of this species. It is tuber- 

 culated posteriorly on the back, but smooth in front; below it is 

 finely granulated to the abdominal and pubic regions ; no light 

 line along the thighs and two phalanges of the 4th toe free.
