PARENCHYMATA. 363 
FAMILY II. 
TREMADOTEA, Rud. 
Our second family comprises those which are furnished un- 
derneath the body, or at its extremity, with organs resembling 
cupping-glasses, by which they adhere to the viscera. 
They may all be united in one genus, or the 
Fascroua, Lin. 
Which may be subdivided in the following manner, according to the 
number and position of their organs of adhesion. 
Festucaria, Schr.—Monostoma, Zed. 
Where there is but one of those organs, sometimes at the anterior 
extremity and sometimes underneath the same end. Found in vari- 
ous Birds and Fishes(1). 
Srricea, Abild.—Ampuistoma, Rud. 
Where there is a cup at each extremity. Found in various Quad- 
rupeds, Birds, &c.(2) 
To this subgenus we must probably approximate the 
(1) Rud., Hist., II, p. 325, and Syn. 82; the Hyrostoma, Blainv., are a division 
of the same, with a depressed body, and cups placed under the anterior extremity. 
Van Hasselt and Kuhl have discovered two new species in the Chelonia midas,
