990 NOTES ON AUSTRALIAN EARTHWORMS, 



be regarded as worthy of generic separation will be considered 

 hereafter. I have a single specimen in very bad condition of what 

 is probably another species of this group from the same district, 

 givea me by Mr. H. R. Whittell. 



CrYPTODRILUS (?) PURPUREUS. 



Cry2^todrihcs purinireus, Michaelsen, *' Oligochseten des Ham- 

 burger naturhistorischen Museums," I. 



Three spirit specimens from two different localities, 47 (juv.), 

 93, and 92 mm. long, 3-6*5 mm. broad ; number of segments 116, 

 131, and 144. 



Colour purplish above, paler below. Prostomium only partially 

 divides the buccal ring (less than half). Segments for the most 

 part bi-annulate, occasionally indistinctly tri-annulate. Setae in 

 eight at first straight longitudinal rows, those of the outer couples 

 more than twice as far apart as those of the inner couples, and a 

 little further than the two couples of each side; in about the 

 posterior third of the body, or on about the last 40-50 segments 

 the setse of the two rows of the outer couple of each side are 

 irregularly placed, sometimes alternating pretty regularly for a 

 few segments, sometimes two or three times as far apart from each 

 other, or from the inner couple, as at others. 



Clitellum not developed, nor any indication of it in any of the 

 specimens. 



Male pore, oviduct pores, and spermathecal pores as in C. unicus. 

 Dorsal pores commence after segment iv, but the first one appears to 

 be rudimentary and not functional. Nephridiopores : the first three 

 dorsad of, the others opposite, the fourth setae on each side as long- 

 as these continue regular, afterwards continuing at the same level 

 irrespective of the setae. 



Alimentary canal as in C unicus. 



Genitalia as in C. fasciatus and C. unicus. 



Nephrida possibly as in C. fasciatus^hut the details not made out.
