The question whether this sjiecies is ideatieal with Gf/iiinodrwti/lus coniiitus of 

 Ogilby {Records Austral. Mna. II. ji. .s) must be negatived at present, although this 

 species is reported from the same district, the Belleaden-Ker. In tlie full descrip- 

 tion which Mr. Ogilby gives of it, the author mentions a strong spinate knob 

 surmounted by a conical tubercle behind the eye : this is absent in our species. 

 Beside other differential characters, I may refer to the form of the intororbital 

 region of G. cornatus, which is described as a deep narrow fossa, owing to the much 

 enlarged and elevated su]iraciliary region. Its tail is described as covered above by 

 minute granular scales, intermi.Ked, except on a rerfehral patcli of the leaf-like 

 e.xpausion, with soft triangular appendages. In our species the granulated part, 

 which is devoid of tubercles, extends as a broad band along the whole length of the 

 muscular portion of the expanded tail. 



There remains the question whether the specimens referred to onr species 

 represent, after all, only a certain condition of growth of the tail of I'hijllurus 

 platarus. This species was originally described from New South Wales specimens, 

 and may be readily distinguished by the absence of the series of slender tubercles 

 which flanks the abdomen of I'll, lichenosus. In the majority of the southern 

 s]iecimens which I have seen, the tail is reproduced and of that appearance which 

 has led to the description of the nominal form, P. incrmis. However, in a few 

 specimens the tail is apparently intact, showing quite a different arrangement of 

 the tubercles, as shown in fig. A of Plate XII. The tubercles are scattereil all 

 over the surface, except in a narrow median line, and the margin of the leaf-like 

 expansion is not lobulate. I have never seen a specimen of P. pl'Uiiru,>s like the 

 one mentioned by Mr. Ogilby (l.c. p. 10), which had a non-tubercular vertebral 

 jjatrh. Also, the margin of the tail of Pli. platnrus is remarkably thick and swollen. 



One of the specimens in the Xatnral History Museum (the one without locality, 

 as mentioned above, and registered ."j8.4.16.4j is especially intere.sting, as it luis 

 the tail reproduced. I have figured its tail on Plate XII. fig. B. It is quite 

 different from a reproduced tail of Ph. platnrus: it is elongate leaf-shaped, not 

 terminating in a long cylindrical portion. Its margin is broad, very thin, and not 

 scalloped; in this specimen no tubercles or spines whatever are developed. 



3. Egernia frerei »p. nov. 



No curved groove behind the nostril. Nasals slightly separated from each 

 other ; posterior frontals forming a suture together ; vertical contracted in tlie 

 middle, twice as long as broad, longer and rather larger than the median occipital ; 

 five supraoculars, of which the second is the largest ; seven supraciliaries : a 

 complete ring of infraoculars, shutting the labials out of the orbit. Three pairs of 

 nuchals, of which the two posterior are very narrow. Ear-opening as large as the 

 eye, with three lobules in front, of which the upper is the largest and obtusely 

 rounded ; the two others small. 



Thirty-four longitudinal rows ol scales round the body: the dorsal are the 

 largest, obtusely biiarinate : the lateral are the same si/.e as the ventral. As to 

 the scales on the side of the neck, those bciiind the ear and in front of the shoulder 

 are very small, and the intermediate visibly smaller than those on the side of the 

 trunk. Six praeauals. 



Tail dejiressed near its root, compressed farther behind. The compressed
