I.—On a Cysticercus from the Peritoneal Cavity of a 
Raccoon-like Dog (Nyctereutes procyonides). By F. G. 
PENROSE. 
[Plate II.] 
In the spring of 1878 the late Prof. Garrod, whilst dissecting 
‘an adult male [of Nyctereutes procyonides| which died on 
the 2nd of February last, the father of a litter of six born on 
May 2nd, 1877,” discovered an enormous number of some 
parasitic form of worm in the peritoneal cavity. He asked 
me to cut sections of one, and from those sections wrote the 
following paragraph when describing some anatomical pecu- 
liarities of the dog in the P. Z.S. 1878, p. 376 :— 
“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 para- 
sitic worms, collected especially about the abdominal surface 
of the liver and the stomach. These worms had ‘heads’ 
much like those of the Bothriocephal, 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 
in each. 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.
