DESCRIPTIONS OF GENERA AND SPECIES 441 



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, FLETCHER, loc. cit. (2), 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. Hob. 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. 



(5) Diporochaeta dicksonia (SPENCER). 

 Perichaeta dicksonia, SPENCER, P. Roy. Soc. Viet., 1892, p. 16. 



Definition. Length, 50 mm. Prostomium complete. Clitellum, XIV XVI. Setae, 2O 22. 

 Genital papillae median XVII/XVIII, XVIII/XIX. Intestine begins in XVII. Last 

 heart in XII. Sperm-sacs in IX, XII. Spermathecae in V-IX. Hob. Fern Tree Gully, 

 Victoria. 



(6) Diporochaeta alsophila (SPENCER). 

 Perichaeta alsophila, SPENCER, loc. cit., p. 17. 



Definition. Length, 50 mm.; number of segments, 104. Clitellum, XIV XVI. Setae, 

 20-26. Genital papillae median on VII, VIII, XVII/XVIII, XVIII/XIX, paired on

Definition. Length, 140 mm. Prostomium complete. Clitellum, XIII-XVII. Setae, 8 on 

 first two segments, 10 up to clitellum, behind this 20-28. Genital papillae paired on 

 XV/XVI-XXI/XXII. Oesopkageal swellings in XIII XV ; intestine begins in XVII.
