546 NOTES ON AUSTRALIAN EARTHWORMS, 



other anteclitellian worm lias about the same dimensions as large 

 examples of L. Novce-Hollandia 3 , but is of a pale flesh-col on r ; and 

 has a saddle-shaped clitellum of about six segments from xxix to 

 xxxv, sometimes taking in about half of xxviii and xxxvi, and 

 incomplete below. 



B. INTRACL1TELLIAN WORMS. 



Notoscolex, n. g. 



Intraclitellian worms with clitellum comprising some or all of 

 segments xiii-xxiii ; male pores two, on segment xviii, on papillae 

 in a line with the intervals between the inner couples of setae; 

 oviducal pores on xiv ; setse in eight longitudinal rows. 



2. Notoscolex Camdenensis, n. sp. 



(Plate VIII, Figs. 1-5.) 



A good spirit specimen (somewhat contracted) gave the following 

 measurements. — Length 148 mm.; breadth (greatest) 9 mm.; 

 length of pre-clitellar region 19 mm. ; length of clitellum 15 mm. ; 

 number ot segments about 220. This is a very good example of 

 average good specimens. Such a worm when living and crawling 

 will extend itself to 18 in. or 2 ft. Of two specimens measuring 

 102 mm. and 107 mm. respectively, and comprising each about 

 200 segments, neither shewed any trace of a clitellum. When 

 alive these worms are of a uniform pale flesh-colour, except that, 

 the integument being very thin, the internal organs shew through 

 it and locally modify the ground colour. 



The anterior portion of the body from somite XIII forward is 

 cylindrical, tapering slightly anteriorly. Behind this, except in 

 the caudal region, the body is perceptibly flatter in spirit 

 specimens, but more nearly cylindrical when alive, and its breadth 

 very gradually diminishes posteriorly ; the last half-dozen somites 

 more circular and rapidly decreasing in size ; mouth and anus 

 terminal. 



Prostomium small, flattened from above downwards, wide as 

 compared with its thickness, in spirit specimens hai'dly projecting 

 beyond the buccal somite, marked inferiorly with one median and
