[174]. Jonstonus, Articul. xiii. p. 21.
But I shall only mention that of Chersydrus, from Nicander in Jonstonus, p. 28. or Chelydrus, called by some a Sea-Snail; which the learned Sir Hans Sloane describes thus——
“That it is more flat than most of the cochlean Marines, consisting only of Circumvolutions, round the Axis of the Shell; of a fine purple Colour.”
He calls it Cochlea Marina[[175]], and not without reason, because of their difference in Magnitude.
[175]. His Voyage to Jamaica, vol. i. p. 34.
The terrestrial Druina lives upon Frogs, and other Insects; many of them are found in Africa-Interior, and the Hellespont by Constantinople. It is a fetid Animal, and sends forth an ill Scent, especially when its Body is wounded[[176]].
[176]. Ælian. Gyllius. Gesner.
This Serpent exceeds most in bulk, and loudness in hissing, which resembles the Cry of Sheep and Goats, ibid. Gyllius makes the Druina to be the Chelydrus, described by the Poet, who makes it a Calabrian[[177]]: Of which, more in another place.
