FURTHER NOTES ON PSEUDEMYS AT 

 PLYMOUTH, MASSACHUSETTS. 



The two short articles in the December "Copeia" 

 having stimulated some new interest in this connec- 

 tion, I have to record the following new ponds in Ply- 

 mouth County. Massachusetts, in which Pseudemys 

 rubriventris has been observed: Great South Pond 

 and Crooked Pond. The Island Pond mentioned in 

 my notes is the one about one-half mile northeast of 

 Gunners Exhange. Hallfield Pond, the existence of 

 which Dr. Lucas doubted, is a small four-acre pond 

 between Hoyt and Boot Ponds. P. rubriventris does 

 not occur in Half-way Pond as far as I know. It is 

 a curious fact that in the ponds where this turtle is 

 found, it seems to be the most common species. It 

 is also of interest that the "Plymouth Sabbatia" and 

 other plants, as well as certain insects, notably dragon 

 flies, which are distributed over the same local areas 

 as this species of turtle, are all southern forms of life.
