DESCRIPTIONS OF GENERA AND SPECIES 505 



Gizzard in, VI ; calciferous glands in XIV-XVI ; intestine begins in XVIII. Septa 

 VI/XIV thickened. Last hearts in XIII. Sperm-sacs in XI, XII ; spermathecae in. 

 VIIl, IX, with small lobulate caecum. Ilab. Burraivang, N. S. W. 

 It is mentioned that the intestine is coiled in a corkscrew fashion, when the 

 worm is contracted.

Definition. Length, 760 mm. ; diameter, n mm. ; number of segments (?). Prostomium 

 incomplete. Clitcllum, XIII XIX, complete. Setae in eight rows as in preceding 

 species. Male pores on two papillae which dovetail in between the ends of two 

 papillae formed by narrow transverse ridges on XVIII and XIX. Dorsal pores

 Septa VI/XIII are thickened. Sperm-sacs in IX, XII ; spermathecae in VIII, IX, with 

 small diverticnlum. Hab. Burrawang, N. S. TV.

Definition. Length, 108 mm. ; diameter, 5 mm.; number of segments, 220. Prostomium 

 incomplete. Setae of outer couples further apart than of inner. Male pores corresponding 

 interval between setae I and 2 ; on a ridge-like swelling which is repeated on VII and 

 XIX. Dorsal pores commence X/XI. Gizzard in V ; calciferous glands in XIV, XV ; 

 intestine begins in XVII. Last hearts in XII. Sperm-sacs in XI, XII ; spermathecae 

 in VIII, IX, with rosette-like caecum. Penial setae present, not ornamented. Ilab. 

 Bulli, Illawarra, N. S. W. 



Genus MICBODEILUS, BEDDARD. 



DEFINITION. Male pores on XVII. Spermiducal glands tubular with penial setae. 



Nephridia difiuse. Gizzards, two. 



This genus is very near to Digaster, The principal reason which leads me to separate 

 the two is the fact that the male pores of the present genus open on to segment xvii 

 instead of xviii. Another feature which may perhaps be of generic value is the fact 

 that only one of the three pairs of calciferous glands opens into the oesophagus ; the 

 other two open into it. This peculiarity of the calciferous gland has been hitherto
