TESTUDINATA. _Tortoise_,--Of the _testudinata_ the land tortoises are numerous, but present no remarkable features beyond the beautiful marking of the starred variety[1], which is common, in the north-western province around Putlam and Chilaw, and is distinguished by the bright yellow rays which diversify the deep black of its dorsal shield. From one of these which was kept in my garden I took a number of flat ticks (_Ixodes_), which adhered to its fleshy neck in such a position as to baffle any attempt of the animal itself to remove them; but as they were exposed to constant danger of being crushed against the plastron during the protrusion and retraction of the head, each was covered with a horny case almost as resistant as the carapace of the tortoise itself. Such an adaptation of structure is scarcely less striking than that of the parasites found on the spotted lizard of Berar by Dr. Hooker, each of which presented the distinct colour of the scale to which it adhered.[2]

The marshes and pools of the interior are frequented by the terrapins[1], which the natives are in the habit of keeping alive in wells under the conviction that they clear them of impurities. The edible turtle[2] is found on all the coasts of the island, and sells for a few shillings or a few pence, according to its size and abundance at the moment. At certain seasons the turtle on the south-western coast of Ceylon is avoided as poisonous, and some lamentable instances are recorded of death which was ascribed to their use. At Pantura, to the south of Colombo, twenty-eight persons who had partaken of turtle in October, 1840, were seized with sickness immediately, after which coma succeeded, and eighteen died during the night. Those who survived said there was nothing unusual in the appearance of the flesh except that it was fatter than ordinary. Other similarly fatal occurrences have been attributed to turtle curry; but as they have never been proved to proceed exclusively from that source, there is room for believing that the poison may have been contained in some other ingredient. In the Gulf of Manaar turtle is frequently found of such a size as to measure between four and five feet in length; and on one occasion, in riding along the sea-shore north of Putlam, I saw a man in charge of some sheep, resting under the shade of a turtle shell, which he had erected on sticks to protect him from the sun--almost verifying the statement of Ælian, that in the seas off Ceylon there are tortoises so large that several persons may find ample shelter beneath a single shell.[3]
