Show 382 THE OLIGOCHEETOUS FAUNA OF NEW ZEALAND. [June 18, elusions as to the distribution of the group to which my results appear to point. (l)The oligochsetous fauna of New Zealand differs markedly from that of Australia ; the characteristic genera, consisting of numerous species, are Megascolides, Pericheeta, and Cryptodrilus (Fletcher, 5). The characteristic New-Zealand form is evidently Acanthodrilus, of which only one species has as yet been found in Australia. Pericheeta, of which a large number of species occur in Australia, is not an abundant form in New Zealand. Rhododrilus and Neodrilus may be peculiar genera. Deinodrilus has not been met with elsewhere. (2) The fauna of N e w Zealand presents a marked agreement with that of Kerguelen (Lankester, 10), Marion Island, Patagonia (Rosa, 14), the Falkland Islands (Beddard, MS.), and South Georgia (Michaelsen, 11) ; in all these places the only genus known being Acanthodrilus. With regard to the terrestrial Oligochseta, therefore, it seems permissible to speak of au " Antarctic fauna." LIST OF MEMOIRS REFERRED TO. 1. BEDDARD, F.
