500 OLIGOCHAETA 



(5) Cryptodrilus fletcheri, BEDDARD. 



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

 PC. Oxleyensis, FLETCHER, Proc. Linn. Soc., N. S. W., iii (2), 1889, p. 1537. 



Definition. Clitellum, XIII XVII, complete except on XVII. Setae in eight rows, the miter 

 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 ; 

 calciferous glands in XI, XII, ventral in opposition. Nephridia paired alternate. Sperm- 

 sacs in IX, XII ; spermathecae in VI-IX, with longish caecum. Hob. 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 

 C. oxleyensis begin vi/vii. There are three pairs of calciferous 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, 325 mm. ; diameter, 10 mm. ; number of segments, 209. Prostomium 

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

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

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

 /.\, XII ; spermalhecae three pairs, caeca two. Penial setae present. Hab. Milton, near 

 Brisbane. 



(b) With diffuse nephridia. 

 (7) Cryptodrilus victoriensis (SPENCER). 

 Megascolides victoriensis, SPENCER, P. R. Soc. Viet., 1892, p. 151. 



Definition. Length, 3 feet ; breadth, iimm.; Prostomium incomplete. Clitellum, 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 

 XI II/ XIV, XI X/ XXII ; in all four. Dorsal pores commence XI/XII. Gizzard in V ; 

 no ra/ciferous gland x ; intestine begins in XI 11. Sperm-saws in XII; sperruat/tecae, 

 I III, J.\, hro iDxdli'-l'iki- ilii-i'i/icii/a. Hal. / icioria (? as to exact locality).
