are attached to the posterior wall of the segment, those in the other three segments 
to the anterior walls. All are of moderate size, situated laterally in the segment, 
and not nearly meeting over the alimentary canal; the edges are produced into a 
number of small rounded lobules. 
The prostates are flattened lobed structures, which do not constrict the alimen- 
tary tube at all; they occupy segments xviii-xix or xviii-xx. The duct, relatively 
stout, almost straight, shining, and of equal diameter throughout, leaves the gland 
in segment xix and runs forwards and inwards. 
The ovaries are large and branching, in xiii. 
The spermathecae (fig. 17) are three pairs. The ampulla varies in form; it may 
perhaps be described as roughly pear-shaped, with narrow end internal, and broader 
end at its junction with the duct. The duct is also pear-shaped, but in the reverse 
direction, so that the broad ends of ampulla and duct join each other, and are sepa- 
rated by a marked constriction. The duct is more regular in shape than the 
ampulla; it is as long and, at its broad end, about as wide as the latter, but it be- 
comes much narrower at its ectal end. A small diverticulum arises from the outer 
side of the duct, not far from its junction with the ampulla; the diverticulum is 
stalked, and dilated at its free end, in which a few chambers can be indistinctly seen. 
A number of micronephridia invest the broad portion of the duct. 
The penial setae (fig. 18) are in maximum length 17 mm., in breadth at the 
middle of the shaft ‘02 mm.; theshaft is almost straight, with a slight curve distally; 
it does not become notably slenderer till close to the tip. Owing to the curve of 
the shaft, the setae are always seen on the slide from one of two aspects; the appear- 
ances on focussing up and down, however, indicate that the tip is flattened in one 
plane, and ends in two projecting points with an incisure between. ‘There are a few,— 
perhaps half a dozen,—irregular rings of fine sculpturings near the free end, which 
are not resolvable into distinct spines under the oil immersion lens. | 
Remarks.—This species seems to be closely related to M. brachycyclus (Schmarda), 
from which however it differs in colour, in the greater interval between the male 
pores and spermathecal pores, in the distribution of the copulatory areas, in the 
shape of the penial setae and the characters of the spermathecal duct. The peculiar 
nephridial condition also would, I think, certainly have been mentioned by previous 
investigators if it were present in M. brachycyclus ; but in view of what has been found 
in M. eschericht var. papillifer (v. ant.) this by itself would not necessitate a 
separation. 
Michaelsen (12) suspects that M. brachycyclus may prove to have the gizzard in 
segment vi, not vii as stated. In this, a near relative, however, the gizzard was in 
segment vil.
