Tlu' accoiiipaiiyins cliarts represent our present knuwleilge of the ran,t,'e of

 represent areas of occurrence, liut express definite localities, thoufjh in Metro- 

 j)olitan districts a single mark may stand for and cover several adjacent produc-

representing, say, a single occurrence, though readily expressetl in words, cannot 

 I)e con\ eniently charted ; in such cases position marks are omitted, though the 

 reference is recorded in the text. The habitat of two species. T. waitii and 

 7\ lahialis. is indefinite, and these do not therefore appear on the charts. 



Though tlie a\aila1)le diita is very incomplete, sonic useful conclusions may 

 be made therefrom. 7", f>oly(/r(iiiniiiciis and 7'. j^rd.viiiiiis occur in (Jueensland, 

 New South Wales, and N'ictoria. 7'. hitiihrrciilatKs and T. australis are found 

 throughout the southern half of the Continent ; T. piiujuis is also a southern.
