well marked race of Carolina and not unlikely a distinct spe- 

 cies. Triung uis from Georgia may be intergrades between 

 typical triunguis and Carolina, or they may be possibly in 

 part hybrids with banri. I will now discuss the specimens I 

 have examined in detail. 



Terrapene Carolina. Specimens from Raleigh show the fol- 

 lowing- characteristics: carapace marked with large yellow 

 spots, these often forming to some extent partially concen- 

 tric figures; keel of the carapace always present, but not 

 marked by a continuous yellow line. Plastron usually black 

 in adults, often showing light spaces, apparently due to abra- 

 sion; in younger specimens it is usually yellow more or less 

 marked with dusk}', head usually with yellow spots. Hind 

 feet usually larger and stronger than in triungis, usually 

 with four claws, but I have seen three specimens with three- 

 clawed hind feet from this locality. Zygomatic arch incom- 

 plete, but the quadratojugal very variable in size and shape; in 

 five specimens examined Feb. 11, 1903, two had the quadra- 

 tojugal long nearly extending to the jugal, nearly completing 

 the arch; in two it was small and triangular, and in the fifth 

 absent altogther. 



The newly hatched young of this species have the carapace 

 broad with the keel marked by a row of yellow spots, the 

 head is without yellow markings in the very young, though 

 usually marked with yellow spots in the adult. 



Terrapene triungis. Five specimen of triungis fromColmesneil 

 in Eastern Texas show the following characteristics: the 

 carapace is shorter and rounder than in any other species 

 examined, the ground color is light brown in all, but the 

 markings show an interesting variation — a living specimen 

 received Oct. 22, 1902, had the carapace marked with a few 

 radiating black lines only, no yellow spots; a shell of one of 

 the others shows very numerous rather faint yellow spots 

 arranged in radiating lines, the upper edges of the lateral 

 plates with some black markings and a few black spots inter- 

 spersed with the yellow spots; a third specimen has very
