CLASS V. ANNELIDA. 
Remarks. Animals of this class have hereio- 
fore been distributed among various divisions of 
the Linnean vermes ; but no naturalist was satis- 
fied with such a distribution. These animals hay- 
ing red blood, and soft Jointed bodies, they seem- 
ed to be excluded from all places in the system. 
The French naturalists have obviated this diffi- 
culty by creating a new class ; and placing this 
class under the grand division Articulata. Ag 
these animals have no limbs for walking, it was 
necessary to make the definition of this division 
more general—referring to their jointed bodies, 
without specifying articulated limbs. They are 
all reproduced like plants with perfect flowers.
