there. In transverse section these columns are seen to be 
formed of about eight or ten cells whose nuclei lie peripherally. 
I could not detect any lumen for the most part. In places a 
lumen appeared to exist. Hach disc of cells (as seen in trans- 
verse sections) is enclosed in a delicate sheath not closely 
adherent to the cells. These rows of glandular cells appeared to 
open on to the exterior, but their external apertures were not 
very evident. They were plainer in Eudriloides Cotterilli. 
Glands in the neighbourhood of the spermatothecal orifices 
are common in the Oligocheta; but the form of these glands 
in the present species is unlike that which I have seen in any 
other, excepting, of course, in the other species of the same 
genus described in the present paper. It may be that 
Michaelsen’s Notykus is furnished with similar glands. The 
figure given by him seems to indicate a similarity. 
The atrium (see fig. 2) differs in structure from that of 
Eudriloides Cotterilli in the fact that the muscular layers 
surrounding the glandular lining are thinner; but, though thin, 
both layers are there. The cellular lining of the atria re- 
sembles that of other Eudrilids and of nearly all other earth- 
worms in being composed of two layers of cells. The layer 
immediately abutting upon the lumen is composed of columnar 
cells. In certain tracts of the atrium near to the external 
orifice this layer of cells is very plain, and resembles such 
columnar cells as line the sperm-duct and their funnel, &e. 
Elsewhere the inner lining of the atria consists of cells which 
are loaded with granules, and of which the nucleus has got 
obscured. The sharply marked layer of epithelium referred 
to is furthermore remarkable by the presence of cilia. 
Cilia are also visible in other parts of the atrium, but more 
obvious along this tract of unmodified epithelium referred to. 
I believe that this is the first record of ciliation of 
the atrium in any earthworm. Thesperm-duct comes to 
lie within the muscular sheath of the atrium as in other Eudri- 
lids, but I have not ascertained the exact spot at which it opens 
into the lumen. 
The terminal pouch of the male efferent system is furnished
