REPTILIA. 
Specimens of the following species of reptiles were exhibited : — 
Croeodilus biporcatus. This is the common crocodile of Pegu, and is very 
numerous in all the salt water creeks of the Traivadi delta. Accidents from 
these animals are not rare, but less frequent than might be anticipated from their 
numbers. They are most dangerous during the rainy season, when they breed. 
The female lays her eggs on some grassy sand bank, and watches them jealously. 
The Burmese and Karees are very fond of the flesh of the Crocodile, and both 
shoot and harpoon it whenever they can. 
Croeodilus palustris. This crocodile occasionally occurs inland. When old 
ones are killed near a large river, it is usually found that their stomachs contain 
several pounds weight of metal, brass, and silver rings, derived from the limbs of 
corpses which have been thrown into the River and devoured by the animal. 
Croeodilus porosus. 
Tryonix gangetica. 
Testudo elongata (Blyth). This is the most widely diffused and abundant 
tortoise in the Province, ranging throughout Pegu and the Tanasserin. It is un- 
known in India. 
Testudo platynotus (Blyth). This species is very closely allied to T. elegans, 
but differs from it in its uniformly larger size, flatter back, and other trifling 
details. It is pretty common in the valley of the Tranadi above the British 
frontier, but does not range down to lower Pegu. 
Cyclemys oldhami (Gray). This box tortoise is remarkable from possessing a 
marginal cartilaginous sature, but instead of the transverse sternal cartilaginous 
binge, it has a pseudo hinge formed by the permanent non- anchyloses of the 
pectoral and abdominal bony plates, thereby permitting a small extent of motion 
though less so than that produced in Testudo by a cartilaginous or true joint. 
Geomyda grandis. 
Batagur trivittata. 
Batayur berdinosei. This species is quite distinct from B. ocellata with which 
Giinther confounds it. The locality also is different, the one being confined to 
Bengal, the other to Burmah. 
Tetraonyx lessonii. 
Chitra indica. 
The Hon. Treasurer, Mr. W. W. Stoddart, F.G.S., then exhibited a 
curious specimen from a Cornish mine. This consisted of a mass of a 
marine and land shells, amongst which were oysters, pectens, helices, and 
bulimi, mixed with sea sand and agglutinated together by the action of
