CHECK[LIST OF THE 



aquatic in all stages. Common throughout Ontario. Feeds upon 

 aquatic insects and small fish. 



In hatcheries or fish ponds it would be decidedly injurious, as it is 

 a very voracious creature. 



Order URODELA. (The Salamanders.) 



Body naked, elongate, subterete ; both jaws with teeth. Tail per- 

 sistent through life ; no external gills in the normally developed adult. 



FAMILY AMBLYSTOMATID./E. 



Toes not webbed ; tongue thick. 



The larvae of Amblystoma often reach a large size before the gills 

 disappear, and sometimes breed while in this condition. 



GENUS AMBLYSTOMA. 



(2) Amblystoma punctatum. 



(Spotted salamander.) 



Common and generally distributed in the southern counties. Feeds 

 upon insects and earthworms. 



(3) Amblystoma tigrinum. 



Of this species I have but a few records for Ontario. It is common 

 in the United States as far north as Minnesota, and will probably be 

 found generally in the northern part of the Province. 



(4) Amblystoma Jeffersonianum. 



(Granulated salamander.) 



This species and the variety A. j. fuscum have been taken occasion- 

 ally in western Ontario and also near Toronto. 



(5) Amblystoma microstomus. 



There is a specimen of this species in the U. S. Nat. Mus. , taken 

 at Hudson's Bay in 1884, which is the only record I have of its occur- 

 rence in Canada. I include it because it will probably be found in north- 

 ern Ontario. 



FAMILY PLETHODONTID^E. 

 GENUS HEMIDACTYLIUM. 



(*) (6) Hemidactylium scutatum. 



A specimen of this species was taken by Dr. D. W. Beadle at St. 

 Catharines, Ont. The only record I have.
