C. excavata, Koch (Beschr. neuer Arachn. und Myriap. 
in Verhandl. Zool.-botan. Gesellsch. Wien, 1867, p. 175), 
is referred by Mr. Cambridge to his new genus Thlaosoma ; 
Gusteracantha turrigera, Koch, 1. c. p. 173, is referred by 
Koch to his new genus T'/to/m( Arachn. Austral. 1, p. 22, 
11. 3 ; pi. 2, fig. 3) ; the latter genus appears to me closer 
to Epeira than G aster acantha. 
19. C. verrucosa. 
$ Cyrtarachne verrucosa, Koch, Arachn. Austral. 
l,p. 16, n. 2; pi. 2, fig. 1 (1871). 
" Upolu,"^(9c/i. Sydney or Moreton Bay, DaweZ. B.M. 
Thorell (Eur. Spiders, pt. 1) believes that Epeira 
paradoxa of Lucas belongs to this genus. 
The Gasteracnntha hemisphccrica of Koch appears to 
be referable to Thorell's senus Cccrostris.
