The evolution of the skull and the cephalic muscles: a comparative study of their development and adult morphology. Part III. The Sauria. The Reptilia
Abstract
[Excerpt from p. 238] This is a large Agamid lizard; the species here described, P. lesueurii, is very common along the streams in the neighbourhood of Bullahdelah, N.S.W. The eggs are deposited in early November along the elevated banks of the stream. As many as twelve have been found in the one hole. It would appear that all are deposited before the hole is filled in, for a lizard caught in the act of oviposition had laid eight and they were not covered at all. The hole is about six inches deep, and the top eggs are only one to two inches below the surface. The eggs hatch out during the following February. I have been fortunate in obtaining nearly two hundred of these eggs in various stages of development. Two full sets of twelve were obtained immediately after being laid, and these were hatched for definite periods and then fixed. Two eggs collected as soon as laid hatched out in 109 and 105 days.
