DESCRIPTIONS OF GENERA AND SPECIES 485 



(i) Digaster lumbricoides (Peebier). 



D. lumbricoides, Peeeiee, Nouv. Arch. Mus., 1873, p. 94, 



Definition. Clitelhm, XIV-XFl. Male pores on XVII {?); a pair of papillae on segments 

 in front of and' heUnd that carrying male pores. Dorsal pores commence IV/V. Gizzards 

 two in V, FIL Sperm-sacs in X, XI. Hal. — Port Macquarie, Australia. 



Peeeiee's description is not very exhaustive; and it is indeed not at all certain 

 whether the species really belongs to the genus Digaster as here defined, in which case, 

 of course, the name will have to be altered. He states, for instance, that the male pores 

 are upon the seventeenth segment. Nothing is said with regard to the nephridia. 



(a) Digaster queenslandica (Fletchee). 



Perissogaster Queenslandica, Fletchee, Proc. Linn. Soc, N. S. W. (a), iii, 1889, 

 p. 1529. 



Definition. Length, 158 mm.; diameter, 8 mm.; number of segments, a20. Prostomium 

 incomplete. Setae of outer couples further apart than of inner, slightly sinuous. Male 

 pores corresponding to interval between setae one and two. Dorsal pores commence III/IV. 

 Gizzards three in V—VII; calciferous glands in XIV, XV. last pair of hearts in XII. 

 Sperm-sacs in XI, XII. Spermathecae in VIII, IX, with a rosette-like caecum. No penial 

 setae. Hah. — Oxley, near Brisbane. 



Fletchee speaks of the sperm-sacs as occupying segments xi-xiii ; I think, how- 

 ever, that in all probability the last pair of reputed sperm-sacs are egg-sacs. 



(3) Digaster perrieri, Fletchee. 

 D. Perrieri, Fletchee, loc. cit., p. 1530. 



Definition. Length, 90 mm.; diameter, 5 mm,.; number of segments, 155. Prostomium 

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

 of inner. Dorsal pores commence X/XI. Papillae on X, XI or IX-XII, and XVII-XIX. 

 Gizzards two. Sperm-sacs in XI, XII. Penial setae with serrated extremity. Hah. — 

 Springwood, N. S. TV. 

 This species is compared by Fletchee with D. armifera ; and both are contrasted 



with D. lumbricoides. He says nothing about the spermathecae.
