necessary either to include this species in my genus Diporochaeta, or to found a 

 new genus for it. 



(4) Diporochaeta terrae-reginae (Fletcheb). 

 Perichaeta terrae-reginae, Fletcheb, loc. cit. (3), iv, 1889, p. 1002. 



Definition. Length, 190 mm.; breadth, 18 mm.; number of segments, 144. Clitellum, 

 XIII-XXII [?). Setae, 40-60. Dorsal pores commence V/VI. Nephridiopores forming 

 a sinuous series. Hab. — Mount Bellenden-Ker, N. E. Queensland. 

 The single specimen of this species examined by Fletcher was not dissected, 



hence its systematic position is a matter of doubt. He considers that it belongs to 



the same division as Megascolex canaliculata. This opinion may or may not be 



correct.
