AND NYOTEREUTES PROCYONIDES. 445 
glans penis is bluntly conical, the urethra ss terminally, much as

any extension directly onwards to the anterior extremity of the hemi- 
sphere. There is scarcely any tendency in the second gyrus to form 
an antero-superior angle; and the sulcus between gyri three and four 
is not quite parallel to the great longitudinal fissure, it diverging 
slightly from the middle line as it goes forward. In these respects 
the brain more resembles that of Canis vulpes* than those of Canis 
familiaris or C. lupus. 
In the peritoneal cavity of the adult male Nyctereutes (which, like 
the half-grown female, had excessive atheroma of all its larger arteries) 
I found an immense number of parasitic worms, collected especially 
about the abdominal surface of the liver and the stomach. 
These worms had “heads” much like those of the Bothriocephalz, 
but larger. My friend Mr. F. G. Penrose has most kindly made 
sections of them, and has demonstrated the existence of a most peculiar 
cavity ineach. This cavity is coiled up within the ovate “head;” 
its lumen is small; and its walls are plicated very extensively, the 
magnitude as well as the number of the folds being great. It opens 
externally at its proximal extremity by one of its ends only. The 
“body” is tenioid in its proportions, and is not segmented. It is 
about two and a half inches in total length, the “ head” being about 
the size of a hemp-seed or a little smaller. 
There are a few general remarks suggested by the above recorded 
facts. 
First, with reference to the colic cecum in the Canide, I have on 
@ previous occasion noticed the aberrant form of that appendage in 
Canis cancrivorus,t+ where it is nearly straight. Two other specimens 
of the species have since passed through my hands, which have been 
entirely confirmatory of my earlier observation. In Nyctereutes 
procyonides the cecum is slightly more caniform than in C. cancrivorus; 
it is a little broader also. 
From the examination of other Canide, I find that the cecum, in 
its twistings, resembles that of Canis familiaris in being turned about 
twice and a half upon itself in C. laniger, C. lagopus,t C. anthus, 
C. fulvus, C. antarcticus, C. azare, Otocyon lalandii, and Lycaon 
pictus.
