Others have the prominence between the suckers armed 
with small points, disposed in radii. Such is again in 
man, 
Tenia Solium, L. Getz. xxi. 1—7. Encyc. xl. 15—22. xli. 
1—7, whose articulations, except the anterior, are more long 
than broad, and have the pore alternately at one of their mar- 
gins. Itis in general from four to ten feet in length, but some 
are found much larger. It is by no means the case that but 
one of these worms exists in an individual at one time, as is 
vulgarly supposed. Its detached articulations are called 
cucurbite. It is one of the most dangerous of the intestinal 
worms, and the most difficult to be expelled. 
From these common teniz, in consequence of the form of 
their head, have been distinguished, the 
TRICUSPIDARIA, Rud., 
Which M. Rudolphi now calls TRIANOPHORA, whose head 
divided, as it were, into two lips or two lobes, has, on each 
side, instead of suckers, two stings, with three points. 
But one is known which inhabits divers fish, the pike, 
perch, &c. Tenia nodulosa, Gm. Getz. xxxiv. 5, 6. Encyc. 
xlix. 12—15. 
BOTHRYOCEPHALUS, Rud., 
Whose head, instead of suckers, has only two longitudinal 
fossettes, placed opposite one to the other. 
Some are found in various fish, and in some birds. 
Among the Bothryocephali themselves, it is proper to dis- 
tinguish 
DIBOTHRYORHYNCUS, Blain., 
Which have at the summit two small proboscides, or tenta- 
cula, bristling with hooks.
