Variation . — Besides the specimen described I have at hand 
two preserved specimens ; one is medium-sized, the other young. 
The medium-sized specimen appears somewhat abnormal or 
diseased, and it is almost impossible to discern the suture be- 
tween the shields of the Carapace; the keel is obliterated save 
on the posterior part of the carapace. Head brown, strongly 
mottled with black, markings on side of head and neck somewhat 
obscured ; each abdominal shield divided completely by a straight 
suture corresponding to hinge of plastron ; elements thus formed 
not contiguous. 
The young specimen has a very strong blunt keel the entire 
length of the carapace; middle costal shields with a small keel 
on their posterior parts; all shields rugose; marginals distinctly 
broader proportionally than in adults ; posterior part of carapace 
very strongly serrate, posterior marginals forming sharp points ; 
a very distinct notch between supracaudals ; anterior part of 
carapace serrate; plastron apparently without hinge; no trace 
” These specimens are unnumbered and belong to the University of the 
Philippines. They were loaned by Prof. Artemas Day and Dr. R. P. 
Cowles.
