the vacuity in septum fV or not (fig. i). The sacs therefore differ 

 from those of the NTaicUdae and Tubificidae, which are constituted 

 by a pocket-hke backward bulging of the septum Hmiting the 

 testis-segment posteriorly ; and correspond rather to the testis- 

 sacs of some of the terrestrial Oligochaeta. 



A number of ripe spermatozoa are found in segment ix, round 

 the mouths of the funnels. These structures are relatively small, 

 with a well-marked rim succeeded b}^ a globular body, the whole 

 exactly resembling the top of a " thistle-funnel " used in chemical 

 laboratories (fig. i). The diameter of the funnel is 50a«; the 

 actual lumen of the funnel is narrowly tubular, the cells of the 

 spherical bulb-like portion being elongated, with peripherally 

 situated nuclei and clear sb'ghtly-staining central portion. 



The male duct pierces septum \\ immediately beyond the 

 funnel, continuing as the vas deferens almost straight backwards 

 through the anterior two thirds of segment xii, bending slightly 

 dorsal wards to enter the atrium on its dorsal, or dorsal and 

 anterior, aspect. The vas is a narrow tube, 6-9/^ in diameter. 



The atrium (penial body) is a small spherical mass, sessile on 

 the ventral body-wall, 55/' in diameter. Its lumen is small, 

 nearer one side, and in horizontal section shaped rather like the 

 figure 3. The body thus consists for the most part of a tightly 

 packed mass of cells, with distinct nuclei, and an investment of 

 muscular fibres. There are no accessory gland-cells The male 

 pore appears on the surface as a slight papilla. 



The ovaries are in segment xii, and the ova after being 

 detached are confined to this segment. There are small ovarian 

 funnels on the anterior face of septum if near the ventral surface. 

 The oviduct was seen in one instance as a minute tube passing 

 backwards from the funnel to open on the ventral surface of the 

 anterior part of segment xiii ; in other cases it was indistinct. 



The spermathecae occupy their usual position, opening on the 

 ventral surface just behind septum *. The ampulla is spherical, 

 of small size, 35|U in diameter, and distinctly marked off from the 

 cylindrical duct. It has no opening into the alimentary canal ; in 

 one of my sections a strand, consisting apparently of a single 

 muscular fibre, connected on the one hand with the muscular 

 layer of the oesophagus and on the other with the muscular 

 investment of the spermatheca, can be seen to pass between the 

 two ; but otherwise they are quite separate. The duct is about 

 18 M in diameter^ and twice as long as the ampulla; a diverticulum 

 is absent.
