Clemmys insculpta (LeConte). 



Our records of first appearance in the spring for the wood turtle vary 

 between the two extremes of March 20, 1915, and May 14, 1906, and we 

 have one mid-winter appearance on January 26, 1913. Three of the rec- 

 ords come in April, two in March, and two in May. An average date at 

 Ithaca, N. Y. , appears to be about April 20. The records follow : May 



14. 1906; April 27, 1908; March 28, 1910; April 27, lyl2; April 20, 1913; 

 May 3, 1914; March 20, 1915. All of these individuals were taken along 

 our stream valleys or actually in the streams. 



During the summer months we seldom see this species. It seems to be 

 in the montbs of May and June that this species breeds. In our Cayuga 

 Inlet valley through which a railroad (Lehigh Valley R. R. ) runs we 

 sometimes find them in late May or early June travelling along the rail- 

 road tracks or along the paralleling stream. 



Some evidence discovered in 1914 may indicate an early May breeding 

 or mating. In a semi-open sandy area of the Inlet valley where two side- 

 streams open into it from different sides we found five of these turtles 

 within a small area. Small willows furnished the only shade. Amongst 

 the grass, against the sand or beside bunches of driftwood we found them. 

 All looked so like the dirty sand that it was hard to find them. They 

 were all females except one. On the same day in the same valley two 

 other parties reported four or five more. One man captured one male 

 and put it in a laundry bag but forgot it. About a week later he found 

 it in good condition where he had left it. 



Some of these turtles were brought home and for the first day we tem- 

 porarily put them in a box in the kitchen. They soon got out and while 

 we were at lunch in an adjoining room we heard a distinct yet subdued 

 note not unlike that of a tea-kettle. We discovered that the male wood 

 turtle was the whistler. We could hear the whistle 30 or 40 feet away. 

 Whenever we brought the male to the middle of the room he would 

 whistle. Once a female responded but its note was not very loud. Fin- 

 ally, we noticed that whenever a male approached a female he would
