PARASITES OF THE ALIMENTARY TRACT 93 
Tapeworms in the Cat. 
There are four tapeworms which may be found in the 
cat. 
These are : 
1. Dipylidium, Tenia elliptica. 
2. Tenia crassicollis. 
3. Afesocestoides lineatus. 
4. Bothriocepbhalus felis (very rare). 
Tenia Elliptica——This worm is practically identical 
with Tenia cucumerina of the dog. 
Teenia Crassicollis——This worm is peculiar to the cat. 
It is a comparatively short worm, seldom exceeding 
2 feet in length, and more commonly only reaching 
5 or 6 inches. The head is rounded and of the same 
diameter as the neck. It possesses four suckers, anda 
rostellum carrying thirty to fifty hooks, arranged in a 
double row. The terminal segments are longer than 
wide. The cystic form is the Cysticercus fasciolaris, 
which occurs in-rats, mice, and other rodents, more 
commonly situated in the liver. This Cysticercus 
possesses several. interesting characters. In length it 
may reach 6 inches, and may thus be mistaken for the 
mature form of some parasite. The head is invaginated, 
and is succeeded by a number of segments, and at the 
other extremity there is a small bladder, with the 
diameter of a pea. 
Mesocestoides Lineatus.—Probably is identical with 
the Mesocestoides found in the dog. 
Signs of Tapeworms.—These are often absent, except 
when the worms are present in considerable numbers. 
The signs then noticeable are capricious appetite, at 
times ravenous, with loss of weight, staring coat, signs 
of irritation, such as drawing the anus along the ground 
- and barking or yelling during sleep. In some in-
