lighter band along the median line, which gradually faded 

 away anteriorly (Fig. 8). This specimen also was darker 

 than the rest. It has a strong resemblance at tirst sight to 

 G. walhallce, but the clear indication of the two light stripes 

 dorsally, and the position of the genital opening, render it 

 distinct from this species. 



0. frosti was found only on the high land lying between 

 the upper tributaries of the Yarra and the Thompson River, 

 and even here was not very common ; its distribution was 

 practically identical with that of G. dendyi. It has been 

 named after Mr. C. Frost, by whom the first specimen was 

 found, and whom I have to thank for valuable assistance in 

 various ways, both on this and on many other occasions. 



G. walhallce, Dendy (Figs. 11, 12, and 13).— This has 

 been already described Ijy Mr. Dendy, who found it at 

 Walhaila, not very far from the district in which we were 

 collecting. It is somewhat leaf-like in shape when at rest, 

 but in this respect forms an intermediate stage between 

 G. spenceri on the one hand, and G. frosti on the other. 

 When crawling, its upper surface closely resembles the 

 former, from which, however-, there is no difficulty whatever 

 in distinguishing it, owing to its light-coloured undersurface, 

 which is covered with brown speckles, as in G. frosti, though 

 the median light stripe present in the latter, is here absent. 

 This form and G. frosti are undoubtedly more closely allied 

 to one another, than either is to G. spenceri, and it is 

 figured here since Mr. Dendy was unable to repi-esent it in 

 the colour-s of life. Its distribution appears to be extr-emely 

 limited. We only found one specimen, and this at the spot 

 which we reached nearest to Walhalla. 



G. alba, Dendy (Figs. 16 and 17). — This again has been 

 de.scribed and figured by Mr. Deirdy, and is represented 

 here because the specimens found wer-e of a notably dark 

 colour for this species, to Mdiich, at the same time, they are 

 undoubtedly referable. This belongs to the leaf-like foi'ms 

 (when at rest), and specimens vary in colour from almost 

 white to orange, and sometimes brown and giey. The two 

 figured were notable for showing a light median sti'ipe, 

 ruirning the whole length of the body dorsally. 



This form is widely distributed in Victoria, being recorded 

 from the hill country extendirrg from Macedon to the East 

 of Mount Ellery, near the borders of New South Wales, in 

 which, however, it has not as yet been found. It is the
