500 OLIGOCHAETA 



(5) Cryptodrilus fletcheri, Beddaed. 



C. fletcheri, Beddaed, P. Z. S., 1887, p. 544. 

 ? C. Oxleyensis, Fletcher, Proc. Linn. Soc, N. S. W., iii (2), 1889, p. 1537. 



Definition. Glitellum, XIII-XVII, complete except on XVII. Setae in eight rows, the outei' 

 further apart than, inner. Male pores on papillae, of which there are also pairs on 

 XVIII, XIX-XXI. Oviducal pore a single 'slit-like orifice.' Gizzard in VI, VII; 

 caleiferous glands in XI, XII, ventral in opposition. Nepliridia paired alternate. Sperm- 

 sacs in IX, XII ; spermathecae in VI— IX, with longish caecum. Hah. — (Queensland. 

 This species may or may not be identical with C oxleyensis. There is nothing 

 in Fletcher's description of the latter to militate against their identification; but 

 his description is incomplete owing to the immaturity of the worms, as is mine in 

 certain points, which ought to have been noticed and recorded. The dorsal pores in 

 G. oxleyensis begin vi/vii. There are three pairs of caleiferous glands ventral in 

 position (I figure three but only describe two). 



(6) Cryptodrilus tryoni, Fletcher. 



C. Tryoni, Fletcher, Proc. Linn. Soc, N. S. W., iv (2), 1890, p. 994. 



Definition. Length, 'ip.^mm.; diameter, 10 mm.; numler of segments, 209. Prostomium 

 incomplete. Glitellum, XIV-XVIII, complete except on ventral surface of XVII. Setae 

 of outer rows remarkably far apart. Gizzard in V ; caleiferous glands in IX-XIII. 

 Nephridia alternate ; last hearts in XIII ; septa, VI/XIV, thickened. Sperm-sacs in 

 IX, XII ; spermathecae three pairs, caeca two. Penial setae present. Hah. — Milton, near 



(b) With diffuse nephridia. 

 (7) Cryptodrilus victoriensis (Spencer). 

 Megascolides victoriensis, Spencer, P. R. Soc. Vict., 1892, p. 151. 



Definition. Length, ^ feet ; breadth, 12 mm.; Prostomium incomplete. Glitellum, XIII-XIV. 

 Setae of outer rows four times as far away from each other as those on inner, irregular 

 at end of body. Male pores on level of interval 1/2. Genital papillae median on 

 XIII/XIV, XIX / XXII ; in all four. Dorsal pores comm.ence XI/XII. Gizzard in V ; 

 no caleiferous glands; intestine begins in XVII. Sperm-sacs in XII ; spermathecae, 

 VIII, IX, two 1 oselte-like diverticula. Hah.- — J'ictoria [Fas to exact locality').
