short distance. The testes are as usual a little asymmetrically placed, 
the left one being slightly anterior to the right one. They are 
practically the same size, each measuring about 5mm. by 3mm. 
The spermadncts (Yd.) are small delicate tubules, very complexly 
convoluted in the region of the testes. About the middle of the 
right kidney and near the anterior end of the left kidney they en- 
large suddenly and then run straight to their openings in the cloaca. 
The ureters (Ur.) join the spermaducts and open into the cloaca 
through the same openings. Their anterior ends branch out into 
numerous branches which spread out over the kidneys. 
The kidneys (K.) are relatively large and bulky. They measure 
10mm. in length and 3mm. in greatest width. Their posterior one- 
thirds are closely apposed. They are not divided up into distinct 
lobes. There is a slight irregularity at about their middle points 
which may indicate a tendency toward lobulation. The kidneys 
are mostly anterior to the anal opening, but there is a small tip of 
their posterior ends which extends behind it. 
The adrenals (Ad.) were present on each side as relatively large 
elongated bodies imbedded in the windings of the spermaduct. 
There was in this form a peculiarity which was not present in 
any of the species already described. This was the presence of a 
large urinary bladder. The bladder (Yes.) is a large flask-shaped 
body which lies just ventral to the cloaca. The larger anterior end 
is supported by two strong ligaments which are joined to the sides of 
the abdominal cavity. The posterior end narrows down to a tube 
like neck which opens into the cloaca on the ventral side at a point 
(x) slightly posterior to the openings of the spermaducts and ure- 
ters. 
(b) female. (PI. I, fig. 1.) 
The ovaries (Ov.) are somewhat elongated, placed symmetrically 
in the body cavity, and are supported by two folds of peritoneum 
which are joined to the walls of the body cavity on each side of 
the vertebral column. 
The oviducts (Ov.) are two large flat tubes, each beginning anter- 
iorly with a wide ostium (Os.). They are thrown into waves in 
the region of the ovaries. Posterior to the ovaries, however, they 
continue with but slight undulations to their openings into the 
cloaca. 
The ureters (Ur.) are like those of the male, and open with the 
corresponding oviducts into the cloaca. 
The kidneys (K.) are similar to those described in the male. They 
are distinctly divided into anterior and posterior lobes, thus realiz- 
ing the tendency shown in the male.
