toward the margin and ending", with decreas- 

 ing intensity of color, about half way be- 

 tween margin and top of shell. The under 

 margin of the carapace was of a bright clear 

 orange red, marked all around with grayish 

 black, almost velvety, round or oval spots, 

 each color sharply defined. The plastron 

 had a few soft gray blotches in a white field 

 along its center line; the rest was orange, 

 light in the middle and growing deeper to- 

 ward the edge. On the part connecting car- 

 apace and plastron a solid dark gray stripe 

 ran close to and along the edge of the first. 

 The markings on the soft parts of the turtle 

 differed only slightly from the true Clemmys 

 irrigata type. As we have not been able to 

 observe other specimens of the same color- 

 ing, we cannot decide whether this was only 

 a variety of Clemmys irrigata or a rare 

 species not described before. 



The Snapping Turtle, Alligator Turtle (Chcly- 

 dra serpentina) is of value to the aquarist 

 only so long as it is very young and small.
