NOTES ON AUSTRALIAN EARTHWORMS, 
Colonr pallid or flesh-coloured, spirit specimens with a tinge of 
browm Prostomium rather depressed, dividing the buccal ring 
slightly. 
Buccal ring narrow (from before Ijackwards), the next three or 
four segments successively longer (from before backwards) and 
wider and biannulate, vi-ix widest and tri-annulate, after which 
the segments are shorter (from before backwards). 
Seta in two couples on each side, the first ventral, the second 
lateral ; the setfe of the former less than -5 ncm. apart; those of 
the latter about 1 mm. or a trifle more ; the two couples nearly 
2 mm. apart. 
CUteUum when complete comprising segments xiii-xvii, and in 
addition in a few specimens the first or the first two annuli of 
xviii, or even a little more in the ventral and ventro-lateral 
region, so as to include the ^ pores ; the whole of xiii not included 
in some specimens ; complete all round except for a large genital 
papiUa on the hinder ventral portion of it. 
Male pores on papillae occupying the two anterior annuli of 
XVIII, extending a little way on either side of the setae of the dist 
couple or altogether dorsad of them, their extremities in line with 
the extremities of the large genitad papdla, the pores themselves 
very inconspicuous, about in line with or a little dorsad of the 
outer seta of each inner couple ; in breeding worms the papillae 
usually connected by an intervening tumid ridge. Oviduct pores 
on xrv, in front and ventrad of the setae of this segment, flush 
with the surface, or sometimes opening towards the ends of a 
transverse shadlow slit-like depression ; spermathecal pores two 
pairs, not interseg mental but on small papillae either on the 
anterior margin of the middle annuli, or between the first and 
middle annuli of segments viii and ix, just in front of and nearly 
in line with the first seta on each side. 
Accessory copulaiory structures or genital papfiUae of a charac- 
teristic pattern are noticeable in all but the very youngest 
and smallest specimens, even in those in which the girdle is
