the two gizzards, the single pair of prostates, and the two vasa 

 deferentia of the worm described by me, sufficiently distinguish it. 



In the segments behind the gizzards as far back as xn there are 

 transverse hearts. 



Small tufts of glandular tubules attached to the ccelomic wall, 

 and sometimes also to the mesenteries probably represent the 

 segmental organs; they are largest in some of the anterior 

 segments. Their external apertures (nephridiopores) are quite 

 undiscernible. 



Hab. — Marrickville near Sydney, Auburn near Parramatta, 



N.S.Wales. 



Obs. — From under stones, logs, pieces of bark after rain ; not very 

 common. This species is readily distinguishable from D. lumbricoides 

 by (l)the gizzards being in consecutive segments instead of in vand 

 vii, (2) the testes being in ix and XII instead of in consecutive 

 segments — x and xi, (3) the clitellum including segment xvn, (4) 

 the setse of the outer couples being further apart than are those of 

 the inner ones, whereas Perrier says that in his species the disposition 

 of the setse is that of Lumbricus, [and (5) the presence of penial 

 setae], 



11. Cryptodrilus saccarius, n. sp. 



Five (spirit) specimens are from 57 to 74 mm. long, and 5 mm. 

 broad ; the longest of them has the preclitellar region 10 mm. long, 

 and consists of about 160 segments. Body uniformly pale or 

 fiesh-colour, cylindrical, posterior region more attenuate. Pro- 

 stomium small, depressed, only slightly imbedded in the buccal ring. 

 Segments widest and most prominent from the clitellum forwards ; 

 the iv and v are bi-annulate, while after vi they are tri-annulate, 

 the anterior primary annuli being subdivided. 



Clitellum comprises nearly five segments, xiii to xvn, a very 

 slight portion on the anterior margin of xiii not included, complete 

 all round, in one case not quite so thick on the ventral portion of 

 xiii, and on xvn slightly encroached upon by the area carrying the 

 male pores.
