382 THE OLIGOCH^TOUS FAUNA OF NEW ZEALAND. [JuDC 18, 



elusions as to the distribution of tlie group to which my results 

 appear to point. 



(1) The nligochsetous fauna of New Zealand differs markedly from 

 that of Australia ; the characteristic genera, consisting of numerous 

 species, are MegascoHdes, Perichceta, and Cryptodrilus (Fletcher, 5). 

 The characteristic New-Zeaiand form is evidently Acanthodrilus, of 

 which only one species has as yet been found in Australia. Perichceta, 

 of which a large number of species occur in Australia, is not an 

 abundant form in New Zealand. Rhododrilus and Neodrihts may 

 be peculiar genera. Deinodrilus has not been met with elsewhere. 



(2) The fauna of New 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 tliese places the only genus known being Acanthodrilus. 

 With regard to the terrestrial Oligochseta, therefore, it seems per- 

 missible to speak of an " .Antarctic fauna."
