P. Peguense, Gray. App., Cat. S. R., p. 70. 



P. megacephalum, Grayl Theobald. Jour., Lin. Soc, Vol. X. 



Colour of young (shell 2 inches) fleshy grey; each of the costal 

 shields with a central black tubercle, beneath bright reddish 

 orange, with a little black about the sutures. Iris pale yellow. 

 Head dark mottled, with a black edged yellow stripe behind the 

 eye. Grows to 14 inches of which the shell is five only. 



Inhabits streams falling into the Sitang and Sal win Pk,ivers. 



Gray in App., Cat. S. R., separates the Pegu species from 

 megacephalum from China. 



It is possible that both species (supposing them to be distinct) 

 may occur in Burmah, but our materials for deciding are very 

 imperfect. The Pegu animal described above is said to be taken 

 at night by men who are led to discover its whereabouts by a 

 pretty loud noise which the animal makes somewhat resembling 

 the cry of a puny fractious child, of the truth of which statement 

 I have received undoubted corroboration. M}'- specimen was 

 given me alive by Sir A. P. Phayre, first Chief Commissioner of 

 British Burmah, to whom it had been presented by some natives 

 who hold these somewhat rare animals in considerable estimation. 



Family Chitrid^. 



Fresh water chelonians with three claws on all feet and 

 extremely weak lower jaws. Feet webbed. 



Chitra, Gray. 



Shell depressed, with cartilaginous margins. Sternum united 

 to thorax by cartilage. Sternal callosities four. Head elongate. 

 Lower jaw very weak. Eyes placed very forward. The semi- 

 diameter across the mandibular condyles is contained more than 

 three times in the distance between the occipital condyle and 

 the palatal opening of the nostrils. Affects estuaries as well as 

 rivers. Young not ocellated.
