of the ureter break up into smaller ones and these in turn into still 
smaller ones until the entire kidney is supplied. The main branch 
of the ureter joins with its corresponding spermaduct, and they open 
Into the cloaca through a common opening (G. ap.) situated on the 
end of one of the papillae on the dorsal wall of the cloaca. 
The general appearance of the kidney and ureter is shown in PI. 
If, Fig. 7. 
In Gerrhonotus infernalis there is a very large urinary bladder 
fVes.), which opens into the posterior portion of the cloaca on the 
ventral side, and its anterior end is held in place by two strong 
ligaments attached to the dorsal wall of the abdominal cavity. 
The adrenals (Ad.) are present on both sides as golden yellow 
foodies lying imbedded in the windings of the spermaducts just an- 
terior to the testes. 
(b) female. (PL I, Fig. 2.) 
In the female we find the most complicated urogenital system of 
any of the forms described in this paper. The specimen examined 
was an adult and measured from the tip of the snout to the anus 
about 15cm. 
The ovaries (Ov.) lie close to the dorsal wall of the abdominal 
cavity. They are not exactly, but almost, symmetrically placed, the 
right one being slightly in front of the left. The specimen was 
Saken in the late fall, and each ovary contained a half dozen large 
-eggs and numerous smaller ones. Each ovary was supported by a 
strong fold of peritoneum which is firmly attached to the dorsal 
wall of the body cavity. 
The oviducts (Ovd.) are large flat tubes which are thrown into 
many wave-like folds. There is a strong ligament (Lig.) to which 
these folds are attached. Each oviduct is also supported by a large 
thick fold of peritoneum (W.) inserted on the dorsal wall of the 
foody cavity. Just before emptying into the cloaca, there is a large 
thickening of muscles around the oviducts. This is not shown in 
the main figure (Fig. 2), but in figure 2a. These thickened muscu- 
lar tubes open into a common tube which in turn opens into the 
cloaca. 
The ureters (Ur.) which are similar to those of the male open into 
the dorsal wall of the short vagina-like formation through two small 
apertures. 
The kidneys (K.) are practically the same as those found in the 
male. 
The adrenals (Ad.) were also present in their usual position; 
A large urinary bladder (Yes.) was found just as in the male. 
-In the specimen dissected, there were found two small tubules
