nants of which still are to be seen in this specimen (a type intermediate between 
figs d and e), are just fading into the light ground colour. 
In one of the specimens from Adelaide (fig. 1), a rather large male, the back 
is uniform olive grey, but still rather well defined from the darker sides. A closer 
examination reveals, however, that there are indications of the same pattern as in 
the specimens from Perth, and in another large specimen from Adelaide we find the 
same markings as in fig. d. Thus, there is no doubt that a colour pattern somewhat 
like this has existed before in the now almost uniform specimens as well, although 
the dark colour has disappeared with increasing age. 
The largest specimens of this species I have seen, are three specimens from 
Moss Vale, New South Wales, presented to the Expedition by Mr. T. STEEL. The 
largest of these (23 mm.) has the back uniform brownish gray without distinct limits 
against the somewhat darker sides, while the two other, only slightly smaller, spe- 
cimens still have rather distinet dark markings. In a fourth specimen of smaller 
size from the same collection (15 mm. between nose and vent) we find an aberrant 
pattern, as shown in fig. k. The markings on the anterior back agree somewhat with 
those in fig. f, although the anterior branches of the x-shaped spot have mostly dis- 
appeared, but on the posterior part of the back the usual median band is very ir- 
regularly toothed. Another different pattern is found in a small female (12 mm.) 
from Perth, fig. 1. The whole back is dark brown with a narrow white vertebral 
stripe, but distinetly lighter than the dark sides. It looks asif in this specimen the 
whole back should fade at the same time without any remaining dark spots. 
Almost as great variations as those of the upper side are exhibited by the 
lower side. In the darkest specimens it is more or less black; the under side of the 
legs is, however, always lighter, and usually a light median stripe extends over the 
dark ground of the chin, throat, and anterior breast. In somewhat lighter specimens 
we find small light dots as well, scattered over the dark ground colour. These spots 
increase in size more and more with age, so that the under surface, especially of the 
females, may become pure white with dark irregular spots. Sometimes this very 
beautiful pattern is to be found in the males as well, but as a rule these are more 
or less dark below, especially on the throat. 
Two specimens captured in copula at Perth, at the same time as the others 
from this locality, Sept. 1910, are remarkably small, the male 13,5 mm., the 
female 16,5 mm.; evidently this species very soon becomes mature. Both have the 
back coloured as in fig. a, but at least in the larger female the anterior triangular 
spot is distinct; the lower parts of the male are uniform greyish brown with the 
chin somewhat darker, and with a narrow light median stripe. The female is white 
underneath with illdefined dark markings. 
Also in other respects than with regard to the colour this species varies con- 
siderably, and the name varia, used for it by several authors, appears to have good 
reasons, although it does not have priority. According to the diagnosis in BoULEN- 
GER'S catalogue the upper side is warty. In some specimens it is 'distinctly so, but 
in some others it is quite smooth. Even the granulation of the under surfaces, al-
