Sternum of Trionyx phayrei. 



I have lately received a specimen of this fine species from Penang. 

 It measures along the curve of the carapace 27" 6'" ; osseous portion 

 of carapace 19" 6'". Breadth in middle 22" 3'" ; osseous portion 

 at same point 20" 6'". Sternum, length of osseous portion 21" 6'". 

 Greatest breadth of abdominal plates 21". Seven osseous plates, of 

 which five are visible and granular ; the anterior pair long and linear, 

 5" 9" x 1", in contact behind, divergent anteriorly. Odd osseous 

 plate semicircular, 7" 5'" along the curve, 1" 3'" in diameter in the 

 mesial line ; anteriorly in contact with the anterior pair, and poste- 

 riorly with the abdominal ones. Greatest length of abdominal plates 

 8" ; they enclose an hour-glass-shaped cartilaginous area, the an- 

 terior portion being the largest, and measuring 4" 3'" in diameter 

 and 6" 8'" in length from the posterior contraction to the oild plate.
