species it is more less impregnated. Prof. Owen figures the organs 

 of a specimen of Zootoca, which had three ova in one oviduct and 

 two in the other. The general arrangement in my specimens was 

 just as is figured in this one. 



The point dealt with in this note is not of any importance, but 

 is I think sufficiently interesting to be recorded, in the hope that 

 others may be induced to take up the neglected subject of the 

 oviposition of our reptiles. 



Note. — After the proof of the above had been returned to the printer, I 

 met with Mr. Krefft's paper " On the Vertebrata of the Lower Darling," in 

 the Proceedings of the Philosophical Society of N.S.W., Vol. I. In this 

 paper the author enumerates a considerable number of oviparous lizards, 

 and gives a good deal of information about them. In addition to Trachydo- 

 sanrus, it is stated that Cyclodus gigas also is viviparous ; but of three 

 species of Hinulia met with — including H. elegans — Mr. Krefft says that it 

 has not been ascertained how many eggs they lay, and he suggests that they 

 may possibly be viviparous, and produce as many as ten or twelve young. 

 I regret my inability to refer to this paper in its proper place. Mr. Krefft's 

 communication shews that the subject of oviposition of Australian reptiles 

 is not altogether a neglected one, and that there is yet room for further 

 observations. 



Notes and Exhibits. 



Professor Stephens exhibited a photograph and a sketch 

 forwarded by Mr. C. Jenkins, representing a fossil from the 

 Devonian formation of the Murrumbidgee Valley, near Yass. 

 This very remarkable specimen is the head of some Ganoid fish, 

 evidently belonging to the Devonian period, and characterised by 

 strong bony scales, deeply sculptured, and united by close sutures. 

 Two of these are perforated by large sub-circular orbits for the eyes. 

 Other portions of the same specimen had been forwarded to the 

 Australian Museum while Mr. Jenkins was engaged in the 

 exploration of the Cavan Caves ; and some other fragments have 

 since, it is believed, been recovered. Mr. Jenkins is inclined to 

 refer it to Asterolepis (which is closely connected with Pterichthys), 

 but chiefly on account of the character of sculpture of the scales. 

 On the same ground, he doubts its relationship to C<£COsteusov Cepha- 

 laspis. Prof, Stephens added that without theactual specimen before 

 them with all its collected fragments, it would be premature to
