Coe and Kunkel— California Limbless Lizard. 
Transverse section through cloacal region of adult male through the 
opening of the vas deferens (v.d) on the apex of the urogenital 
papilla. The diverticulum of the ureter is essentially similar to 
that of the female in the previous figure. The horizontal partition 
between the cloacal chambers is here shown as a very thick band 
(h). x28. 
Transverse section of the same specimen somewhat more posterior, 
through the opening of one of the ureters. The posterior end of 
the horizontal partition (h) is completely surrounded by the pos- 
terior chamber. x 28. 
Transverse section of aborted left oviduct from near its middle 
portion, showing the numerous well developed glands which open 
into its lumen. x 146. 
PLATE XLVI. 
Urogenital organs of adult male from ventral side. The cloaca is 
represented as a transparent structure so that the openings of the 
urinary (w) and genital ducts (v.d) and the basal portions of the 
retracted phalli (ph) may be seen. x3. 
Transverse section through adult male posterior to cloaca and pass- 
ing through the distal portion of the retracted phalli. The section 
is slightly oblique, so that the phallus on the right shows the two 
terminal pits (t.p) while that on the left doesnot. The strong 
constrictor muscles (c.m) are shown. Large masses of adipose 
tissue (jf) are situated on either side of the middle line between 
the vertebral column (vr) and the pouches of the phalli. x21. 
Ideal reconstruction of cloacal chambers of adult female. The 
cloaca is represented with the left half removed along the middle 
line, showing the relations of the posterior cloacal chamber (p.c) 
and the dorsal (d.c) and the ventral chambers (v.c). The genital 
papilla is seen projecting into the dorsal chamber from the dorsal 
side of the horizontal partition (h). Folded condition of posterior 
chamber is also shown. x7. 
Cloaca of adult male. The ventral wall has been cut away, thus 
removing the bladder and allowing the pouches of the phalli and 
horizontal partition to be seen. x5. 
Cloaca of adult male, contracted somewhat differently from that in 
the previous figure. The cloaca is represented as if split slightly 
to the left of the midventral line and spread open. The ventral 
wall of the posterior chamber has been removed so that the phallus 
pouches are not shown. A transverse section of the cloacal region 
contracted as represented would have the appearance of fig. 36. 
x 5, 
Cloaca of adult, showing the lateral pockets at posterior end of 
rectum, A small section of the ventral wall in which the bladder 
opens into the cloaca has been removed and the cut edges of the 
rectum have been pulled aside to expose the chambers more fully.
