well-defined faunas are, however, readily separated, and contrasted 

 — viz., the temperate and the tropical, as represented, on the 

 northern, eastern, and southern coasts. Only six genera of the 

 present group — viz., Oncinoptu, Stenorhynchux, Huenia, Hyaxtemus, 

 Cryptopodia and Gonatonotux seem to be common to the two 

 contrasted zones, which may be regarded, as separated by the 

 parallel of about 25° of south latitude. Characteristic of the 

 northern region are the genera Egeria, Campoxcia. Xenocarcinus, 

 Jfen&thius, Parathoe, Chlorolibinia, Xaxia, Tiarinia, Schizophrys, 

 Lambrux, Zebrida, Harrovia and Chlorinoidex ; and of the southern 

 Achaux, Halimus, Paramithrax, Paramicippa, Jficippoides and 

 Gonatorhynchm. 



Xone of the Australian species extend beyond the Oriental 

 Region, though one of them — Campoxcia retu*a — ranges at least as 

 far west as Mauritius. Three extend as far north as Japan — viz., 

 Huenia proteus, Hyastenus d ('acanthus, and Schizophrys aspera ; while 

 ten connect tropical Australia with Xew Caledonia, Borneo, the 

 Philippines or China, viz., Henctthms moHOtseros, JEgeria Herbxtii, 

 Lambrux longimanu*. L. turriger. L. harpax. L. hoplonotus, L. 

 calappoides, L. affinis, Cryptopodia fornicata and Gonatonotus 

 pewtag&nm. Of species common to Australia and Xew Zealand 

 there seem to be eight, viz., Stenorhynchus fissifrons, Huenia 

 bifurcata, Paramithrax peronii, P. barbicornis, P. sternocostulatus, 

 Hyaxtenu.x diacanthus, Paramicippa spinosa, and Lambrux nodosus, 

 though it is not unlikely that the list may subsequently require 

 modification, as in many of the earlier collections ''Xew Zealand n 

 and "Australia " appear to have been regarded as almost inter- 

 changeable terms.
