488 DESCRIPTIONS OF SOME NEW ARANEID^ OF N.S.W., 



upon the superior surface there is a faintly visible leaf -like design, 

 and an ornamental scheme of tracery commencing near the centre, 

 and continuing to posterior extremity ; the sides are chrome- 

 yellow, relieved by a series of faint markings as indicated in the 

 figure; ventral surface yellowish-green at the middle, and yellowish- 

 brown laterally.

In 1870 the Rev. O. P. Cambridge, F.Z.S., described and 

 figured a spider under the name of Thlaosoma distinctum* which, 

 judging by his figure (fig. 36), appears to bear a superficial 

 appearance to the one herein described, and which is now 

 included in the national collection at the Australian Museum. 

 The specimen upon which Cambridge founded his species was 

 an old and dry example; moreover it was a single specimen, and 

 vaguely labelled " New Holland." It is, or was, in the Hope 

 Collection, University Museum, Oxford. 



Although Cambridge's figure (fig. 36 above referred to) appears, 

 as I have pointed out, to bear a superficial appearance to my 

 specimen, his description and supplementary figure (fig. 37) do not 

 agree in several important details. If, to the possibility that the 

 Hope specimen was an immature example — which Cambridge 

 was unable to determine — it be borne in mind that the type was 

 also dry, it will be readily conceived that differences, both in 

 appearance and coloration, from a fresh example would only be 

 natural. Nevertheless there are points mentioned in Cambridge's 

 description which one would hardly expect to undergo change, 

 however old or dry the specimen should be. 



It is impossible, in the absence of the type, to say positively 

 whether the example in my possession is distinct or not, and,
