large seminal vesicle. The seminal vesicles of the hinder 
pair in the eleventh segment are touching each other, as 
well as those of the first pair in the tenth segment, but they 
are nevertheless totally isolated. The seminal vesicles of 
the first pair seem to have a small communication with each 
other. Two pairs of irregular sac-like sperm sacs in the 
eleventh and twelfth segments, each sperm sac communi¬ 
cating with the seminal vesicle lying before it in the pre¬ 
ceding segment. 
Prostates: Glandular part large, occupying about five 
segments, somewhat longer than broad, with some very 
deep incisions and a great number of less deep incisions 
and furrows. Duct nearly straight, much shorter than the 
glandular part is broad; in situ totally hidden beneath 
the glandular part. The duct* is opening directly; there 
is no copulatory pouch. 
Spermathecge of different sizes, those of the first pair 
smaller than those of' the third pair and larger than the 
middle ones. Ampulla pear-shaped or sac-like. Duct 
much thinner than the ampulla, but nearly as long. The 
short extreme distal part piercing the body wall is abruptly 
much thinner. A single diverticulum opens into the duct 
of the main pouch just before it enters the body wall. The 
diverticula are tender, club-shaped, and of different lengths. 
Those of the hinder spermathecae are nearly as long as the 
main pouch—at least distinctly longer than the ampulla ; 
those of the first pair of spermathecse are about as long as 
the duct of the ampulla. The distal end of the generally 
very tender stalk of the diverticula is a little thickened 
and sharply bent, opening in the direction from beneath 
to above into the duct of the ampulla. 
Remarks .—This interesting little species of Pheretima is 
standing quite isolated in its genus on account of the

position of the spermathecal pores. The particular pig¬ 
mentation and the singular shape of the body are giving 
to P. Moultoni a habitus quite uncommon in this genus.
