The genus Perinidium may be known by the furrow that runs transversely round the body, and is furnished with cilia. The integument of the body is mendiranous. The Tripos Perinidium is remarkable for its power of shining by night. It may lie recognised by the shelly case, which is concave, smooth, and is developed into three horns, two being long and the other comparatively short. Tlie longer horns arc in front. Its length is about l.)()th of an inch. The Kerona also belongs to this order, and is found in fresh water, where it may often be seen in considerable Iicsides the usual cilia, it is furnished with instruments of progression that enable it to climb and creep, and are formed like bristles or booklets. Its length is rather variable, but is aljout equal to that of the Perinidium. Two species may be found ii any vegetable i illustration, bat! make their resi of cilia.
