(8) Megascolides roseus, Spencee. 

 M. roseus, Spenoeb, loc. cit., p. 153. 



Definition. Length, 175 mot.; breadth, 6 mm. Prostomium complete. Clitellum complete, 

 Xlll- Xrill ; saddle-shaped in XVI -XVIII . Setae of each couple close together 

 anteriorh/ behind, further away. Male j)ores on a level with interval betioeen two setae 

 on inner pair. Oviducal pores ventral of and anterior to innermost seta. Genital 

 papillae: one between male pores, a pair on XVII, four pairs on XIX/XXIII, getting 

 to be closer together behind. Dorsal pores commence behind clitellum. Gizzard in F ; 

 calciferous glands in XF, XFIj intestine begins in XFIII. Sperm-sacs in XII; sperma- 

 thecae Fill, IX, rosette-shaped diverticulum. Hab. — Warragul. 



(9) Megascolides attenuatus, Spencee. 

 iVE, attenuatus, Spencee, loc. cit., p. 155. 



Definition. Length, 200 mm. ; breadth, 1-3 mm. Prostomium incomplete. Clitellum, 

 XIII-XFIII. Setae of outer couple slightly further apart than ventral. Fourth row 

 irregulari in last ten segments. Oviducal pores in front of ventral of inner seta. Dorsal 

 pores commence F/FI. Gizzard in F ; no calciferous glands. Sperm-sacs in IX, XII ; 

 spermathecae Fill, IX, with small diverticulum. Hab. — Warragul. 

 Spencee mentions that there are numerous minute grape-like processes round 



spermiducal glands ; these may be glands such as occur in this situation in 



Perichaeia. 



(10) Megascolides rubens (Fletchee). 

 Cryptodrilus rubens, Fletohee, Proc. Linn. Soc. N. S. W., ii (3), 1888, p. 381. 



Definition. Length, ^^ mm.; breadth, 4 mm.; number of segments, 114. Prostomium 

 incomplete. Clitellum, XIF-XFI, complete. Setae in eight rows ; ventral closer together. 

 Male pores in line with second seta; in front of and behind each a small papiilla, 

 through one of which protrude (?) penial setae. Dorsal pores absent. Calciferous glands 

 in X-XIII; intestine begins in XFI. Last hearts in XII. Sperm-sacs in XII only, 

 but two pairs of funnels. Spermathecae (?). Pinial setae present. Hab. — Mount Wilson. 



FIjETCHER remarks that in segments vi and vii is a thin walled globular portion 

 of oesophagus, both of which may be gizzards.
