has the appearance of a broad bilobed disk. Its length in the middle 
line is *8", its greatest breadth -1", greatest thickness °2". 
The vasa deferentia (vd) enter the upper part of the prostate 
without any manifest dilatation or trace of vesiculee sentinales. 
The floor of the prostatic portion of the urethra is raised in the 
middle line into a distinct narrow ridge, which enlarges into a rounded 
prominence *6" below the neck of the bladder, and again imme- 
diately contracts, and after + inch entirely subsides. On each side 
of the prominence is a tolerably deep depression. There is no dis- 
tinct median cul de sac, or uterus masculinus ; and the vasa deferentia 
appear to empty themselves on the anterior surface of the before- 
mentioned eminence, as a minute orifice could be seen there, though 
too fine to admit a bristle. 
The membranous portion of the urethra is 1'8 in length and 
capacious. Its linmg membrane is thrown into longitudinal folds. 
Near its anterior termination the ducts of Cowper’s glands enter. 
These bodies are oval, with compressed sides meeting at an angle at 
one border, the other border being broad and rounded. The length 
of each is °6'’, its greatest width -4’; the duct is °7'’ long. 
The bulb is very prominent, with a thick muscular covering. The 
erector penis is large ; and there is a pair of strong retractors on the 
underside of the organ. As far as can be ascertained by external 
examination, the penis agrees with that of the Hyzena in possessing 
no bone, though this structure, so conspicuous in most of the Car- 
nivora, is represented by the hard central terminal portion of the 
glans before mentioned. Not wishing to injure this unique speci- 
men, I have not made a section through this. 
The generative organs of a male striped Hyeena are described by 
Daubenton. As far as can be made out from his account and the 
figure which accompanies it, they are an almost exact counterpart to 
those of Proteles. 
In a specimen of the same parts of Hyena crocuta, in the College- 
of-Surgeons Museum, the glans is very like that of Proteles ; but the 
lips of the upper slit are less conspicuous and do not appear to meet 
over the hard apex, which also is much less prominent. The chief 
difference, however, is in the prostate, which, though of the same 
general form, is greatly reduced in size, being but half an inch in 
length, and rather less in breadth. 
ANAL GLANDS. 
As before mentioned, immediately above the anus, and, in fact, 
having a common external aperture with the termination of the in- 
testine, is a wide transverse follicle, or pouch, lined by a soft thin 
membrane of a greenish colour, studded over with minute orifices, 
each in the centre of a small papilla. This sac is 13" in width, and 
1" in depth ; on each side, rather more than }" within the cutaneous 
margin, is an aperture large enough to admit an ordinary-sized probe. 
The walls of the saccular depression are glandular, *2" thick, and 
of a very dark olive-green colour, Some of the longitudinal bands
