1903.] NEW SPECIES OF EARTHWORMS. 215 
The spermathecal pores are paired, while the male pore is single 
and median (text-fig. 36, p. 214). 
The two former pores are upon the boundary line of segments 
xil./xill.: each is somewhat eye-shaped in contour and corresponds 
exactly in position to the outermost of the ventral couple of setz. 
The single and median male pore lies on the boundary line of 
segments xvil./xvill. It is very large and conspicuous, with 
radially folded margins, indicating, perhaps, the possibility of the 
extrusion of the bursa propulsoria, 
The internal organs, unfortunately, were much softened, and 
therefore the female reproductive apparatus was rather difficult to 
decipher. The nature and relations of the other organs of the 
body were not so difficult to ascertain. 
As in many, if not in all, Kudrilide, the last pair of hearts 
occurs in segment xi. In front of these were four distinct pairs. 
The dorsal vessel is single throughout. I have not been able to 
study the alimentary system in detail, but I have ascertained 
that the present species is a member of the section Eudrilacea by 
virtue of the existence of an unpaired ventral median alimentary 
gland in segment x., which showed on a microscopical examination 
the usual laminate structure of these glands, not at all to be 
confounded, even in a badly preserved specimen like the present, 
with the totally different though corresponding organs in the 
other subfamily of the Eudrilide. There are also a pair of these 
glands in segment xuli., of an oval form, which contain abundant 
crystals, such as are met with in other genera.
