                               ANNULATA.


Animal soft, elongated, vermiform, naked or inhabiting a tube, which it
never entirely quits; the body furnished either with segments or
transverse wrinkles; often without a head, eyes or antennæ; without
articulated feet, but most of them having in their place bristly,
retractile knobs, disposed in lateral rows: mouth subterminal, either
simple, orbicular, with lips, or in the form of a proboscis; often with
jaws, a knotted longitudinal medulla, and nerves for sensation and
motion; the blood red, circulating by means of arteries and veins:
respiration by external or internal branchiæ, which are sometimes
imperceptible. _Four Families._

_Animal._ The gills, or respiratory organs dorsal, or disposed
lengthways on the body.

_Shell._ Supposed to be tubular. One species.

Arenicola piscatorium.


                     2. Genus _Siliquaria_. Pl. V.

_Animal._ See Arenicola.

Shell very thin, conical, tubular, involuted in a spiral manner, loosely
and irregularly; aperture circular, sharp edges, interrupted in the
middle by a notch, extending like a slit through the greater portion of
its length, and stopping abruptly at some distance from the summit.

_Animal._ Respiratory organs not determined, supposed to be at the
posterior part of the body.

_Shell._ Tube thin and slender, open at both ends, encrusted externally
with sand and fragments of shells. One species.
