Notoscolex tasmanianus, Fletoheb, loc. cit., p. 607. 



Definition. Length, ^']o mm. ; breadth, 12, mm. ; number of segments, about 200. Prostomium 

 incomplete. CUtellum, XIII-XXII. Setae in eight rows, the outer row further bach, 

 the other row generally sinuous. Male pores on interval between setae i and 1. Oviducal 

 pores to inside of inner seta. Dorsal pores commence between segments XII/XIIl. Gizzard 

 in Y ; no separate calciferous glands ; intestine begins about XIX. Last heart in XIII. 

 Septa, V/XIII, thickened. Sperm-sacs in IX, XII ; spermathecae without caeca in

(la) Megascolides gippslandicus (Spencer). 

 Cryptodrilus gippslandicus, Spenoeb, P. R. Soc. Vict., 1893, p. 13a. 



Definition. Prostomiutn complete. CUtellum, XIII- XVII , only developed dorsally. Setae 

 anteriorly in couples, posteriorly irregular. Male pores on level with interval between 

 two inner setae. Oviducal pores ventral of and anterior to innermost seta. Dorsal 

 pores commence III/IV. Gizzard in Y ; calciferous glands in XIY, XV ; intestine 

 begins in XVII. Dorsal vessel double from segment VI to near end of body. Sperm-sacs 

 in IX, X; spermathecae in Y-IX ; diverticulum one-quarter length of sac simple. Hab. — 

 Croajingolong, East Gippsland. 



(13) Megascolides intermedius (Spencer). 



Cryptodrilus intermedius, Spencer, loc. cit., p. 133. 



Definition. Length, 175 mm.; breadth, 6 mm, Prostomium incomplete. CUtellum, 

 XIY- XVII I. Setae in couples except at very posterior end, where outer irregular. Male 

 pores on level of first seta. Oviducal pores ventral of and anterior to first seta. 

 Dorsal pores commence V/VI. Gizzard in V ; no separate calciferous glands; intestine 

 begins in XIX. Last heart in XIII. Testes one pair. Sperm-sacs attached to anterior 

 wall of XII. Spermathecae in VIII, IX; small rosette-like diverticulum. Hab. — 

 S. Warragul, Gippsland. 



This species is stated by Spencer to have a second pair of sperm-sacs in xiv ; 

 these must surely be the egg-sacs.
