DESCRIPTIONS OF GENERA AND SPECIES 499 



(2) Cryptodrihis canaliculatus, FLETCHER. 

 C. canaliculatus, FLETCHER, loc. cit., iii (a), 1889, p. 1534. 



Definition. Length, 250 mm. ; diameter, 5-5 mm.; number of segments, 265. Prostomium 

 incomplete. Clitellum, XIII-XVIII, complete. Setae of outer couples widely separated. 

 Male pores on papillae preceded and followed on the same segment by similar papilla, 

 of which there are also a pair on the next segment. Dorsal pores commence VIII/IX. 

 Gizzard in V ; calciferous glands in XXIII, lying below the gut ; intestine begins in 

 XVI. Nephridia, paired, alternate. Sperm-sacs in IX, XII ; spermathecae in VII IX, 

 caeca 2. Penial setae present. Hob. Forbes, N. S. W. 



(3) Cryptodrilus sloanei, FLETCHER. 

 C. Sloanei, FLETCHER, loc. cit., p. 1536. 



Definition. Length, 71 mm.; diameter, 5 mm.; number of segments, 150. Prostomium nearly 

 complete. Three pairs of calciferous glands in XI, XIII, lying below gut. Last hearts 

 in XIII. Sperm-sacs in IX, XII ; spermathecae three pairs, caeca 3. Hab. Coona- 

 barabran, N. S. W. 



It is not stated in so many words that this species has paired alternating nephridia ; 

 I infer, however, from its location in the neighbourhood of G. canaliculatus, and its 

 comparison with this species and with C. mediterreus, that the nephridia are of 

 that kind. 



(4) Cryptodrilus manifestus, FLETCHER. 

 C. manifestus, FLETCHER, loc. cit., p. 1538. 



Definition. Length, Jo mm.; diameter, 5-7 mm. ; number of segments, 190. Prostomium 

 complete. Clitellum, XIV-XVII, complete. Setae of outer couples further apart than 

 of inner. Male pores ventrad of innermost setae (which appear to be absent?); on XVII, 

 XIX, and next three or four segments, papillae. First dorsal pore, YIII/IX. Gizzard 

 in V ; calciferous glands in X-XIII ; intestine begins in XVI. Nephridia, paired, 

 alternate. Last hearts in XII. Sperm-sacs in IX, XII ; spermathecae in TI-IX, with 

 a single caecum. Hab. Waterfall, Bulli, National Park, N. S. W. 

 This species is very near to C. fletcheri, but is distinguished by having four instead 



of two or three pairs of calciferous glands.
