while struggling to escape. 
The Australian Lizard that next in order to Chlamydosaurus claims attention 
on account of its bizarre aspect is the so-called Spinous Lizard, or Mountain Devil, 
Moloch horridus. This species is found very abundantly in the semi-tropical district 
of the Gascoigne, in Western Australia; it also inhabits parallel latitudes of South 
Australia, and has been rarely taken in central Queensland. The earliest notice of 
this singular lizard occurs in the Hon. Sir George Grey’s “Journals of Discovery 
in North-West and Western Australia,” published in the year 1841. In this volume 
there is also given an excellent figure of it, accompanied by its technical description by 
Dr. J. E. Gray, then Keeper of the Zoological Department of the British Museum, 
to which the specimen was consigned. 
The reason why such formidable appellations as “ York Devil” and “ Mountain 
Devil,” by which this species is popularly known in Western Australia, have been 
conferred upon it, is difficult to find, for there is probably no other representa- 
tive of its class that is possessed of less potentiality for hurt or evil. Doubtless 
the appearance conveyed by the chevaua de frise of spines and tubercles, with which 
its body and limbs are armed at all points, added to the horn-like development of 
the two anterior head spines, represent the chief attributes that have linked this 
harmless lizard with so dire a name. Did this small species, which rarely exceeds 
six or seven inches in length, attain to the dimensions of a crocodile, or even that of 
some of the larger Monitors, it would reasonably take rank among the most 
formidable-looking of living creatures. It is not so many years, indeed, since 
such a huge fossil representative of Moloch horridus was supposed to have been 
discovered, and was described and dilated upon as such in eloquent terms by the 
late Professor Sir Richard Owen, under the title of Megalania prisca. According to 
that accomplished physiologist’s original description, this terrible reptile was no 
less than fourteen feet or more long. It possessed a flattened skull somewhat 
resembling that of an ox in shape, 1 foot 10} inches in breadth, and that was armed 
with as many as nine horn-like prominences. This skull and several joints of a 
long, hollow tail sheath, which bore a singular resemblance to that of the extinct 
gigantic Armadillo, Glyptodon, represented the basis upon which this lacertilian type 
was established. Further material, however, derived from the same source, the 
Australian tertiary deposits, and also those of Lord Howe Island, off the Australian 
Coast, elicited the fact first demonstrated by Professor Huxley, that these fossil remains
