Young of the Wood Tortoise Chelopus insculptus Some time during the early part of October, 1919. the well-known Washing- ton aquariculturist, Mr. Edward S. Schmid, received a consignment of a large number of very young pond turtles of several species, all of which had been taken by collectors in the District of Co- lumbia. Among these interesting speci- mens occurred one, the like of which he had never seen before of all the thou- sands of young turtles he has possessed in his time; neither was it known to me, for I had never seen one like it, either in life or literature. With his usual gen- erosity, Mr. Schmid duly presented me with this curious little chelonian, and it is now in my possession, alive, and in excellent condition. A few hours after receiving it, I handed it to Dr. Leonard Stejneger, Chief Curator of the U. S. National Museum, for identification. He found that it had never been figured in any work known to him, and, turning to the great chelonian collection of that in- stitution, it was found to be, upon com- parison, the very young of the Wood Tortoise (Chelopus insculptus), which Doctor Stejneger surmised before any comparisons were made. It was found that the National Museum possessed but three young specimens of this species, and the smallest one of them was fully three times the size of my specimen, and quite difiterently marked. Later on I made photographs of it, natural size, while it was under water in a shallow, white-lined pan, and these give it from above and below. It is shown here in Figure i, while the figures of the young of our common Snapping Turtle (C. ser- pentina) are presented in Figure 2 for comparison. These latter I also photo- graphed from life from specimens kindly placed at my disposal by Mr. Schmid: the upper and lower views are of different individuals.
