air of cirri, from which I infer
that this species has a pair of long, articulated, caudal appendages: he
asserts that each cirrus has ten segments; the cirri are short and
little curled. M. Lesson remarks, that "deux languettes bifurques
occupent le bas de l'ouverture ovale:" I can hardly doubt but that these
are horny scuta of nearly the same shape as in _A. minuta_. The whole
animal seems to be extremely transparent, and of a "jaune-citron clair."
MM. Quoy and Gaimard, however, remark, that different specimens vary
from white to yellow. Entire length two inches, of which the capitulum
is fourteen French lines. The peduncle is narrow and short.

3. ALEPAS CORNUTA. Pl. III, fig. 6.

_A. apertura parva, leviter prominente: scutis nullis: capitulo
plerumque tribus, parvis, compressis eminentiis secundum carinalem
marginem instructo._

Orifice small, slightly protuberant; capitulum without horny scuta;
generally with three small flattened projections along the carinal
margin.

Outer maxillae with the inner bristles divided into two groups; segments
of the posterior cirri extremely numerous, each with one pair of main
spines; inner rami of the fifth and sixth cirri rudimentary.

St. Vincent's, West Indies, attached to an Antipathes, collected
by the Rev. L. Guilding.

_Capitulum_ globular, slightly flattened, smooth, translucent, entirely
destitute of valves; orifice slightly projecting or tubular, parallel to
the longitudinal axis of the peduncle, with the edges sinuous; it
appears more tubular than it really is, from the convexity of the part
of the capitulum immediately beneath the orifice. Three small, flexible,
horny, irregular prominences project from the carinal margin; one at the
bottom of the capitulum; a second about half-way up it; and a third
generally close to the orifice; but their positions vary a little, and
the prominences vary still more in shape and size, being either rounded
and very small, or much flattened and considerably prominent; they are
imperforate; in the membrane under them a few tubuli may be seen, which
are not elsewhere visible; their summits are roughened with very minute
points and beads of chitine; others, still minuter, are scattered over
the whole capitulum.

_Peduncle_ short, narrower than the capitulum, into which it insensibly
blends; strongly wrinkled; surface of attachment wide; position with
respect to the branches of the corall
