General remarks. In 191 2 we made the following extended notes on the 

 tadpoles of this species: "In a small pond at the edge of the Lee's clearing 

 and just outside the swampy wooded edge of Billy's Lake we found on June 

 12, 1912, the tadpoles of the narrow-mouthed toad. In the same pond were 

 Gamhusia affinis, Biifo tadpoles, Rana sphenocephala tadpoles and green 

 frog eggs and adults. The pond was 15 x 10 feet in dimensions and 3 or 4 

 feet deep. Here we took half grown, mature and transforming tadpoles of 

 this species. On June 24 the same stages could still be found as on the last 

 days of our trip (i.e., in July). Some of the tadpoles would not have trans- 

 formed before September or October. The description of the tadpoles 

 follows : 



"The back is fuscous, olive brown or light brownish olive or raw umber, 

 rarely with a few white spots; the belly may be clear white. Oh the throat 

 the fine thickly set dusky specks of dorsal color surround small white areas; 

 the rest of the venter is mottled, blotched or reticulated, the white patches 

 being defined by a reticulum of dorsal color. The mottling is most prominent 

 on the sides of the belly. In some the belly is entirely white with no reticu- 

 lations and with fine speckings. In many on either side where dorsum meets 

 venter there is discontinuous white band from in front of the insertion of the 

 hindhmb well forwards toward the future position of the arm. The belly 

 coloration foreshadows that of the adult only in the latter the white spots 

 are much smaller and not so large or blotch-hke. The muscular part of the
