18 CHECK LIST OF BATRACHIANS AND REPTILES OF ONTARIO 



GENUS AROMOCHELYS. 



(*) (22) Aromochelys odoratus. 



(Musk Turtle.) 



This small Turtle is occasionally found in Lake Erie and St. Clair, 

 but it is not common. It has a strong, unpleasant musky odour. 



FAMILY EMYDID^E. (THE POND TURTLES.) 



Carapace ovate, broadest behind, the margin having a tendency to 

 flare outwards ; highest near the middle ; plastron covering the whole 

 under surface. Toes broadly webbed in the aquatic species, scarcely 

 webbed in the others. The pond turtles feed largely upon small fish and 

 consequently would be injurious in preserves and hatcheries. 



GENUS GRAPTEMYS. 



(23) Graptemys geographicus. 



(Map Turtle.) 



This species seems to be peculiarly distributed in the Province. It is 

 not uncommon in the west, and I have received specimens from the County 

 of Lanark in the east, but so far have not seen it in the waters of Lake 

 Ontario. 



GENUS CHRYSEMYS. 

 (24} Chrysemys picta. 



(Painted Turtle.) 



The commonest and most beautiful Turtle we have. Hundreds of 

 them may sometimes be seen sunning themselves upon logs and other 

 floating debris in our southern marshes. Aquatic, only leaving the water 

 to deposit its eggs. 



GENUS CLEMMYS. 



(25} Clemmys insculptus. 

 (Wood Tortoise.) 



Tolerably common in western Ontario, less frequently found east- 

 waid. Largely terrestrial. 

 (26) Clemmys guttatus. 



(Speckled Tortoise.) 



Common in south-western Ontario. They are usually found in warm 

 mud ponds from which they crawl out to sun themselves in the manner of 

 C. picta. 



GENUS EMYDOIDEA. 



(*) (27) Emydoidea blandingi. 

 (Blanding's Tortoise.) 



Very rare. Dr. Gamier records one specimen taken at Lake St. Clair 

 by Mr. Buck, and others have been taken near Belleville.
