LONG-STALKED ASCIDIA with oval body

The Afcidia clavata, one of the rareft and mod 
curious animals of its genus, has already been de- 
fcribed in the prefent work. The fpecies now re- 
prefented is much allied to it in general appearance, 
but differs in the fliape of the body, which is much 
rounder, and in the lituation of the apertures, which 
are terminal inftead of lateral, as in the former ani¬ 
mal. The body is of a reddiili color, and fmooth; 
the ftem of a darker red, and rough, or befet with 
minute bridles or fpicula. It is a native of the 
Northern fcas, and is generally found affixed either 
to dones, rocks, or large lliells.
