tissue. There are no accessory glands in the neighborhood of 

 the "prostates." 



The ovaries lie in the Xlllth segment and are not large,^ in 

 spite of the fact that the worm is large and fully mature. The 

 position of the ovary on each side is just over the separate sperm 

 ducts of that side vi^here they emerge from the septum. 



The spermathecge are present to the number of 4 pairs in cor- 

 respondence with the external apertures already described. The 

 main pouch is spherical to oval in contour and there is a distinctly 

 marked distal portion leading to the exterior. The single diver- 

 ticulum of each spermatheca opens into this duct not far from 

 its external orifice. On the under surface of each spermatheca, 

 near the junction of the thin-walled pouch with the thicker- walled 

 duct, is an adherent tuft of nephridial tubules apparently quite 

 like those which Michaelsen ' has figured in his species, Phere- 

 tima martensi. The diverticulum is longer than the spermatheca 

 and consists of a narrow duct, often coiled upon itself near its 

 end or wrapped around the terminal, cylindrical portion of the 

 spermatheca, and an oval pouch containing the sperm which is 

 much smaller than the spermatheca. 



Pheretima orientalis sp. nov. 



A number of examples of this species are all small, slender 

 worms, whose color, for the most part, has been removed by the 

 spirit in which they were preserved. They now exhibit a whity- 

 brown color save for the clitellum which is a dark brown. The 

 length is some 98 millimeters ; the diameter, 0.75 millimeter. 

 The setae form perfectly continuous rows upon the segments of 

 the body, there being neither dorsal nor ventral gaps. 



The clitellum commences a little posterior to the commence- 

 ment of segment XIV and extends nearly as far as the setse of 

 segment XVI, say % XIV — % XVI. All of its segments have 

 seise which are quite conspicuous in most cases. Those of the 

 XVIth segment completely encircle the segment, which fact 

 may be correlated with the absence of any glandular develop- 

 ment upon the greater part of that segment. There is in fact 

 no reason why the setse should be absent. I am not so certain 

 whether the setse form complete circles upon the other segments 

 of the clitellum ; however, there is no doubt that they extend in 

 every case for a considerable distance to the right and left of the

 species.
