ments, those of one side apparently being put into a small 
communication, those of one segment separated from one 
another. Two pairs of large sac-like sperm sacs in the 
eleventh and twelfth segments being connected each with 
the seminal vesicle lying just before and beneath in the 
preceding segment. Each large sperm sac bears dorsally 
a small appendix. A pair of smaller, grape-like super¬ 
numerary sperm sacs depend from the septum 12-18 into 
the thirteenth segment. 
Prostates with rather small two-lobed glandular part, 
which occupies the sixteenth to twentieth segments. The 
surface of the glandular part is roughened by a net of 
furrows and more or less deep incisions. The duct is 
about as long as the glandular part, rather thick, bent in 
an 8-like manner. It is opening into a large, nearly semi- 
globular, copulatory pouch. 
SpermathecaB: Ampulla irregularly sac-like and thick. 
Duct about half as long as the ampulla, moderately thick, 
covered all over by nephridial tufts. A single diverticulum 
enters the duct of the ampulla at the point where it enters 
the body wall. The diverticulum consists of a short 
sausage-like sperm room about twice as long as thick, and 
a very tender, more or less strongly bent, stalk which is 
about as long as the sperm room, if not a little longer, and 
sharply set-off from the latter. In the whole, the diverti¬ 
culum is somewhat shorter than the main pouch (ampulla 
+ duct). 
Remarks.—Pheretima poiana belongs to the group of 
P. merabahensis, Beddard & Fedarb,* * * § P. pliilippina, Rosa,t 
P. impudens, Mich.,]; and P. bindjeyensis , Mich. § The 
new species is distinguished from P. merabahensis by the 
great distance between the male pores, which are said to 
be “close together ” in P. merabahensis. In this character 
P. merabahensis seems to equal the P. philippina, in 
which the male pores are lying in the seventh or eighth 
row of setae (of about thirty-five rows of setae of one-half of 
a segment). I was able to examine a specimen from the 
Philippines which doubtless belongs to Rosa’s species, and 
I can confirm this character. The distance between the 
centres of the slit-like male pores is relatively rather
