DESCRIPTIONS OF GENERA AND SPECIES 491 







(8) Megascolides roseus, SPENCER. 

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



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

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

 anteriorly behind, further away. Male pores on a level with interval between 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 V ; 

 calciferous glands in XV, XVI ; intestine begins in XVIII. Sperm-sacs in XII ; sperma- 

 thecae VIII, IX, rosette-shaped diverticulum. Hob. Warragul. 



(9) Megascolides attenuatus, SPENCER. 



M. attenuatus, SPENCER, loc. cit., p. 155. 



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

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

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

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

 spermathecae VIII, IX, with small diverticulum. Hab. Warragul. 

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



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



Perichaeta. 



(10) Megascolides rubens (FLETCHER). 

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



Definition. Length, 55 mm. ; breadth, 4 mm. ; number of segments, 1 14. Prostomium 

 incomplete. Clitellum, XIV-XVI, complete. Setae in eight rows ; ventral closer together. 

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

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

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

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



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

 of oesophagus, both of which may be gizzards.
