or proboscis. The neck is short and thick, transversely 
plicated, and the reproductive organs are in a single series on 
one edge. If in considerable numbers, this species may pro- 
duce serious symptoms, such as loss of flesh, tight skin, loss 
of strength and spirit, and general debility. 
The Sheep Tape-worm (Tenia expansa Rudolphi). 
This species, which is found both in sheep and cattle, grows 
to the length of eight or ten feet, varying in breadth from a 
quarter of an inch to upward of an inch, in large specimens. 
The head is very small with four suckers directed forward, © 
and close together. The neck is scarcely distinct, or very 
short. The posterior border of the joints are uneven, divided 
up into rounded lobes and notches, or wavy. The reproduc- 
tive organs are double, opening on each edge of every joint. 
Its young stage is unknown, and consequently the source 
from which the sheep obtain it. It does not appear to be very 
common in this country, judging from the few cases recorded. 
In Germany it is very common in sheep. It does, without 
doubt, produce effects in sheep similar to those caused by the 
tape-worms in man. 
Tenia cucumerina Bloch, of the Dog. 
This species is very common in the small intestine of the 
dog. It grows to the length of ten or fifteen inches up to 
nearly ten feet, with a width of one-twelfth to one-eighth of 
aninch. The head issomewhat rhomboidal, with four suckers 
and a central proboscis, which is surrounded by three circles 
of claw-shaped hooks, the whole number being about 48. 
The mature joints are elliptical, or shaped somewhat like the 
seed of a melon or cucumber. From this peculiarity it takes 
its name. There are two genital orifices to each joint, one 
in the middle of each edge. The eggs are much fewer in 
each joint than in most other tape-worms. Its development 
is unknown. It has been supposed that the larve live in flies 
or other insects. 
When in large numbers in a dog, it occasions more or less 
severe symptoms, especially if associated, as it usually is, 
with several other species of tape-worms and round-worms. 
It can be expelled by the same remedies mentioned under 
. gti icrosoft® 
some of the previous species.” “”"s°
