Observations on the Prilled Lizard, Chlamydosaurus kingi. By W . SAVILLE K E N T , F.L.S., F.Z.S., &c. [Received October 23, 1895.] (Plate XLL) The Frilled Lizard, Chlamydosaurus kingi, is a native of the Northern or tropical districts of Australia, occurring in tolerable abundance in both the Eastern, or Queensland, and the Northwestern districts of that island-continent. The habits of the species are essentially sylvan, its favourite haunts being the more or less thickly wooded scrub-lands, and its chief resort tbe trunks and lower limbs of the larger trees. The most remarkable structural feature of Chlamydosaurus, and from which it derives its popular title, is, as recorded in its earliest description by Dr. J. E. Gray in the Natural History Appendix to Captain King's 'Survey of the Coasts of Australia,' vol. ii. 1826, the extraordinary development of the cuticle in the neighbourhood of the neck. |
