- In some systems of zoölogical classification, a term applied to invertebrate animals which exhibit annelism or annulism: approximately synonymous with the Cuvierian Articulata, or the modern Vermes together with Arthropoda, but used with great and varying latitude of signification.

Sorry, no etymologies found.
For, as the nerves everywhere follow the muscles, and these are attached to the various bones, we see how it happens, that the tracts in which distinct developments of colour appear, should so often be marked out by the chief divisions of the bony structure in vertebrates, and by the segments in the annulosa.
Shuckard, Newman, and Westwood have been the principal scientific men who have attended to species of annulosa.
They are red-blooded and hermaphrodite, and form a link of connexion between the annulosa (white-blooded worms) and a humble class of the vertebrata.
In the annulosa it is not distinct, although we must also remember that insects do produce enormous ravages and annoyance in many parts of the earth.
The polypi vaginati, in the crustaceous covering of the living mass, and their more or less articulated structure, represent the annulosa.
An enumeration of some other examples of the natatorial type, as the cephalopoda (instanced in the cuttle-fish) in the mollusca; the crustacea (crabs, &c.) in the annulosa; the owls
