8o Mr. Home's Description of the Anatomy 
are very large in the male, but small in the female. The open* 
ing of the meatus urinarius, and the orifices of the glands, are 
represented in Plate IV. 
The penis is short and small in its relaxed state ; and its body 
does not appear capable of being very much enlarged when 
erected. The prepuce is a fold of the internal membrane of the 
verge of the anus, as in the bird ; and the penis, when retracted, 
is entirely concealed. 
The glans penis is double; one glans having its extremity 
directed to the right, the other to the left ; and, as they supply 
two distinct cavities with semen, they may be considered as two 
penises. This is an approach to the bird, many of which have 
two. Each glans has, at its extremity, pointed conical papillae, 
surrounding a central depression. In one glans, the papillae are 
five in number, in the other four. When the urethra is laid 
open from the bladder into the rectum, about half an inch from 
its termination it communicates with the proper urethra of the 
penis, which afterwards divides into two, one going to each 
glans, in the centre of which is a cavity communicating di- 
rectly with the papillae, the points of which are pervious, forming 
the orifices by which the semen is evacuated. 
The vasa deferentia open into the membranous part of the 
urethra, before it comes to the root of the penis. 
Not being aware of so extraordinary a structure, and the parts 
not being in a perfect state of preservation, they were too much 
injured by dissection before it was discovered, to admit of their 
being prepared by injection. The appearance of these parts is 
delineated in Plate IV. 
There was no appearance of vesiculae seminales. 
The female organs open into the rectum, as in the bird. Just
