The second family, 
TREMADOTES, Rud., 
Comprehends those which have under the body, or at its 
extremities, some organs in the form of cuppers, by which 
they are attached to the viscera. 
A single genus might be formed of them, to which might 
be given in common the name of 
FASCIOLA, L., 
But which may be subdivided as follows, according to the 
number and position of the cuppers. 
FESTUCARIA, Schr. MONOSTOMA, Zeder., 
Have but one cupper, sometimes at the anterior end, some- 
times under this same end. They are found in several birds 
and fishes. 
STRIGEA, Abildg. AMPHISTOMA, Rud., 
Have a cupper at each extremity. Some are found in several 
quadrupeds, birds, &c. 
We should probably approximate to them 
CARYOPHYLLEUS, Bl. 
In which he head is dilated, fringed, and has underneath a 
sucker furnished with two lips not very easily distinguished. 
Another similar sucker is sometimes perceivable under the 
tail. 
But one is known, taken from divers fresh water fishes, and 
particularly common in the Bream. 
Distoma, Retz. and Zéder., 
Have a sucker, or mouth, at the anterior extremity, and a
