neck only, presents a not inconsiderable likeness to a stiffened beard. As an outcome 
of the conspicuous resemblance which to a considerable extent subsists between the 
abnormally developed neck membranes of the two species between which comparisons 
have been instituted, it is found that the two forms are apt to be confounded with 
one another. The name of the Frilled Lizard is not only frequently misapplied to this 
Amphibolurus, but the species is figured under the name of Chlamydosaurus in one or 
more standard Natural History works. In addition to the material structural differences 
between the two forms, it is worthy of remark that the true Frilled Lizard, 
Chlamydosaurus, is an essentially tropical type, while Amphibolurus barbatus is as 
characteristically a denizen of the southern or temperate areas of the Australian 
Continent. 
The Bearded Lizard is one among the several Australian representatives of its 
tribe that is not unfrequently brought to England and placed on view in the Reptile 
House of our well-appointed Zoological Gardens. Although it so happened that this 
particular species was not included among those which the author kept alive, and 
had an opportunity of making a special study of, during his residence in Australia, 
the facilities were afforded him while engaged upon this work of securing the 
accompanying photographs and chronicling the data here recorded of an English 
imported specimen, very kindly placed at his disposal by Mr. A. E. Harris, F.Z.S., an 
enthusiastic admirer of the Lacertilian Zoological group. 
Among the points inviting investigation with reference to Amphibolurus, was 
that of its method of perambulation, its share with Chlamydosaurus of the title 
of the Frilled Lizard having brought about the attribution to it of a correspond- 
ing bipedal plan of locomotion. The contour of the body and the small relative 
size of the hinder limbs, however, by no means encouraged sanguine anticipa- 
tions in this direction, and as, in fact, practical experiments proved, the gait 
of Amphibolurus differs in no way from that of the generality of Lizards. One 
peculiarity, however, which it was found to share with Chlamydosaurus was the 
free use it made of its tail as a weapon of defence, striking vigorously with this 
organ right and left at the writer’s hand or other presented objects on occasions of 
abnormal excitement. With the Varani, as hereafter noted, the caudal appendage 
constitutes a most effective offensive and defensive weapon. As compared with 
Chlamydosaurus, the body scales of Amphibolurus are considerably larger, those 
bordering each side of the spine being most conspicuously so and also notable for 
their sharp trenchant edges. It was found, in fact, that these larger scales could
