Description of Vicforici) Edrthwormff. 185 



Reproductive system. Testes, two pairs attached to the 

 anterior walls of seti;ments 10 and 11. Ciliated rosette.s in 

 the same .segments, which are full in mature specimens of 

 sperm. 



Prostates, coiled, tubular, and in segment 18. 



Sperm sacs attached to the anterior wall of segment 12, 

 saccular in form. 



Ovaries attached to the anterior wall of segment 18; 

 oviducts open into the same segment. 



Spermatliecse in segments 5-U» Each consists of a long 

 sac, with a simple diverticulum, about one-quarter the lengtl» 

 of the sac. 



Habitat. Tanjil Track, near the source of the Yai-ia 

 River. Collected during an expedition of the Field Natui-a- 

 lists' Club of Victoria to the Yarra Falls, near the source of 

 the River Yarra. 



(4) G. frenchi, sp. n. (Figs. U), 11, 12, 6G). Spirit specimen.s 

 3 inches long, | inch broad. 



Prostomium dovetailed into the peristomium to the 

 extent of -^ or f . 



Clitellum occup3'ing segments i-t-16 ; not very distinctly 

 marked ventrally. 



Setne in four couples, regularly arranged, except at the 

 posterior end of the body. Prominent. The inner couple 

 nearer together than the outer, the fourth row being dorso- 

 lateral. For the posterior one-.sixth of the body the two 

 outer rows are irregular and on the last few segments all are 

 except the innermost on each side. 



Male pores on papillae on segment 18, at the level of the 

 interval between the inner couple of setre on each side. 



Oviduct pores on segment 14, close to the anterior margin 

 and slightly ventral of the inner setse. 



Spermathecal pores, five in number, just on the very 

 anterior boundaries of segments 5-9, at the level of the 

 interval between the inner couple of setse. 



Accessory copulatory structures as follows :— Small oval 

 patches anteriorly on segments 10 and 11 at the level of tlie 

 spermathecal ducts. Patches on each side of the body at 

 the level of the interval between the inner couple of aetve 

 from segments 16-21. Each patch is composed of a small 

 part of ^wo contiguous segments and the pairs are united 

 across the mid-ventral line by glandular ridges.
