correspond to the septal glands in certain genera of aquatic 
Oligocheta. These glands extend back as far as the 7th 
segment. 
The nephridia are paired structures. The first pair lie in 
the 5th segment; they are not absent in any of the genital 
segments; but in the llth, 12th, and 14th segments the 
nephridia are more or less rudimentary. That they are present 
can be made out without any difficulty, for the large vesicular 
cells which clothe the nephridia from the 9th segment onwards 
can be readily seen. 
The degeneration of the nephridia in these segments must, 
as it appears to me, be correlated with the development of the 
genital ducts, or rather their funnels; so complete is this 
degeneration in the case of the nephridia of Segment x1v that 
nothing is left but a mass of vesicular cells to tell of the former 
existence of a pair of nephridia in this segment. 
As to the reproductive organs, the testes lie in Segments x 
and xt, in which are also to be found the funnels of the sperm- 
ducts;. there is nothing unusual in either their structure or 
their position. The same segments, with the addition of the 
12th, contain the sperm-sacs. The sperm-ducts and atria are 
precisely like those of the West African Gordiodrilus 
elegans, and call, therefore, for no particular remark. The 
ovaries are in Segment x111, and there is nothing remarkable 
about them or their ducts. There are however, and I have 
not yet observed this in the genus, egg-sacs in Segment xtv. 
The spermatotheca are in Segments viii and 1x. 
§ Calciferous Glands in the Eudrilide. 
I have studied with care the calciferous glands in two of the 
species described in the present paper, viz. Eudriloides 
Finni and Stuhlmannia variabilis. These two species 
and another which I have lately described in a paper com- 
municated to the Zoological Society, and named Eudriloides 
durbanensis, show a peculiar form of these glands which 
present various points of interest. I find also that Eudri-
