1006 NOTES ON AUSTRALIAN EARTHWORMS, 



some specimens on x ; in one specimen none on x but a swelling 

 and one fossette on xii. On xvii and on xx (on the latter some- 

 times more like the structures on xix but a little closer together) 

 the ventral surface in the interval devoid of setae tumid, with two 

 fossettes, one on either side of median line, which may be con- 

 fluent ; on XIX a pair of papillae each with a fossette in front of 

 the interval between the first and second setae. The above is the 

 typical arrangement ; but specimens vary both in regard to the 

 number of these structures and the extent to which they are 

 developed; and there may be an additional one on xxi. 



Dorsal pores commence after .segment iv. 



Hah. — Burrawang, N.S.W. 



Var. c. (i) : — Nine specimens 35-74 mm. long, 2-4 mm. broad; 

 number of segments 82-95. 



Spemathecals opposite the interval between the second and 

 third setae, or e\^en opposite the third setae. 



Accessory structures : the whole ventral surface of x and xi as 

 far dorsad on each side as about the third seta, raised and swollen ; 

 opposite the interval between the first and second setae a pair of 

 fossettes. A pair of papillae on xvii, and a pair on xix, closer 

 than (J papillae ; a slight papilla on xviii in median line in some 

 s^^ecimens. 



Ilab.—Mt. Victoria, Blue Mts., N.S.W. (collected by Mr. A. 

 G. Hamilton). 



(ii) : — Nine specimens not in good condition 36-50 mm. long, 

 2-3 mm. broad ; number of segments 66-94. 



Allowing for the poor condition of the specimens not distin- 

 guishable from the preceding ; the accessory swellings on x and 

 XI are as in that form, but though xvii, or xvii and xix are 

 modified, papillae are not very evident. 



Eab, — Raymond Terrace and Morpeth, N.S.W. 



(iii) : — Fifteen specimens 26-60 mm. long, 2-4 mm. broad : 

 number of segments 75-115.
