In these three last groups the hooks of the mouth are well marked; their strings are but slightly elongated, and sometimes the posterio1• portion of the body is provided with other appendages. .In consequence of a recent examination, I place here the CHoNDRAOANTHus, Laroch. Where the 'mouth is also furnished with hooks, and the sides of tlt.e body with appendages, so extremely various as to form and number, that in process of time we shall have to subdivide them. Thus, in some, we observe on each side two sorts of arms more or Jess clongated(2). In others there are several pairs partly forked(3), or even more ramous(4). Some again hav.e a slender neck, and a wide body slashecl on the edges( 5). Act. Suec., 1751, and Encyc. M6thod., Vers, pl. LXXVIII, f. 13, 18;-L.
