Description of Victorian Eartlcwovms. 153 



SetPB, ill four cou[)]es, the rows of" the inner couple being 

 dose together, those of the outer far apart ; the third row is 

 lateral, and the fourth dorsal iu position. Tiie two outer 

 rows are sinuously arranged in the middle and )K)sterior 

 [)arts of the body. 



Male pores on slight elevations on segment LS. 



Oviduct pores on segment 14, ventral of, and anterior to, 

 the innermost setse. 



Spermathecal pores, two pairs between segments 7 and 8, 

 S and 9. 



Accessory copulatory structures. Two ridges, one half on 

 segments 19 and 20, the other half on segments 20 and 21 

 ventrall3^ 



Alimentary canal. Gizzard in segment 5. No true 

 calciferous glands, but sliglitly vascular swellings in seg- 

 ments 13-17. Large intestine commences in segment 18. 



Circulatory systeu). Dorsal blood-vessel single. Hearts 

 in segments 7-13. Supra-intestinal and lateral blood-vessel 

 in the region ol the hearts. 



Excretory system. Plectonephric. No large paired 

 nephiidia present. 



Reproductive system. Testes, two pairs in segments 10 

 and li, with rosettes in the same segments. 



Prostates, coiled, tubular, in segment IS. 



Sperm sacs, grape-like, attached to the anterior walls of 

 segments 12 and 14>, the former large. 



Ovaries in segment 13, into which open the oviducts. 



Spermathecae, two pairs in segments 8 and 9, each 

 consisting of a long sac, with a short diverticulum at the 

 base. 



Habitat. Dandenong Ranges. Collected by Mr. J. Hulmo. 



This is evidently very closely allied to M. ohscuvus., from 

 which, however, it differs amongst other points, in the fact 

 that the sperniatheca has only one small diverticuluip, 

 whilst two are present in M. ohscuTUs. 



(0) M. rossus, sp. n. (Figs. 58, 59, 60, 81). Length of spirit 

 specimen 7 inches (length when alive 10-12 inches), 

 one-quarter inch broad. 



Prostomium completely dovetailed into the peristomium. 

 The latter ribbed. 



Clitelluni strongly mai'ked, including segments 13-18, 

 only the posterior dorsal part of the former, and the anterior
