ANNELIDES. 
Clespine, Sav . — Glossopora, Johns* * * § . 
The Clesiiines have a widened body, a posterior cup only, and a 
probosciform moutli without a sucker ; some of them, liowever, may 
be found to belong to the family of the Planariye f, 1 consider them 
more closely allied to the Phylline, Oken and to the Malacohdellcs, 
Blainv.§, which also have broad bodies, and are deprived of a pro- 
boscis and anterior sucker. They are parasitic animals. 
Goudius, Lin. 
The body resembling a thread, the only mark of the articulations 
being slight, transverse plicae ; it has neither feet, branchiae, nor ten- 
tacula. Internally, however, a nervous system is perceptible in a 
knotted cord. Perhaps it will be necessary in the end to place them 
among the cavitary Intestina, like the Nemertes. 
They live in fresh water, in tlie mud, and in inundated grounds 
which they perforate in every direction. 
The different species are not yet well distinguished; the most 
common — Gordius aquaticus, L., is several inches in length, 
almost as fine as a hair, and brown, with blackish extremities.
