994 NOTES ON AUSTRALIAN EARTHWORMS, 



Male pores not readily determinable. Oviduct pores two, on 

 XIV on little papillae, in front and a little ventrad of the first setae ; 

 spermathecal pores four pairs, intersegmental from v-ix, on little 

 papillae (the fourth pair of these modified as above) about opposite 

 or slightly ventrad of the first setae. 



Dorsal pores commence after segment iv. Nephridiopores not 

 visible (probably a pair on each segment except a few anterior 

 ones). 



Alimentary canal : gizzard in v (or vi) ; in some of segments 

 ix-xvi there are dilatations some of which may be calciferous 

 glands, but there are no pairs of pouches ; large intestine com- 

 mences about XVIII but is small and compressed between the 

 prostates as far back as xxii. 



Genitalia : two pairs of vesiculae in ix and xii ; two pairs of 

 testes and ciliated rosettes in x and xi ; a pair of prostates 

 extending through about four segments, xviii-xxi ; genital ducts 

 rather long and twisted ; vasa deferentia not observed. Penial 

 setae absent. Ovaries and oviducts as usual ; spermathecae four 

 pairs in vi-ix, stalked pouches with a single rudimentary club- 

 shaped caecum on the duct near its exit, the caecum shorter than 

 the duct. 



Nephrida : a pair of convoluted tubules to a segment. 



Last pair of hearts in xii. 



iTaS.— Eltham, Victoria (collected by Mr. W. W. Smith). 



This distinct species is easily recognisable by the remarkably 

 dorsal situation of the outer couple of setae on each side, an exagger- 

 ated condition of the arrangement which is so frequently met with 

 in species of this genus. Its affinities are not very clear. 



Crtptodrilus Tryoni, n.sp. 



One (very soft and not well preserved) specimen 325 mm. long, 

 10 mm. broad ; number of segments about 209. 



Buccal ring not divided by the prostomium. Colour (much 

 bleached) more or less pallid, slightly tinged with brown superiorly. 

 Body not canaliculate.
