; in _L. cauta_ and _L.
truncata_ they are large, of the same shape, but smooth.

_Maxillae._--These are larger, compared to the mandibles, than is usual
with pedunculated Cirripedes; they differ in shape in the different
species, being either nearly straight on their edge, and notched or not
(fig. 10), or notched with the inferior part forming a double prominence
(fig. 12); the spines on the inferior angle, which is sometimes slightly
produced, are always crowded together into a brush, and are finer than
those on the upper parts. The apodemes are less straight than is usual,
and at their origin take, in all the species, a rather abrupt bend;
their extremity is enlarged into a little disc, which in _L. dorsalis_
is covered with strong points, but in the other species is, as usual,
smooth.

_Outer Maxillae._--The inner margin is slightly concave, and in _L.
truncata_ alone, the bristles are hardly continuous, being interrupted
in the middle part. The olfactory orifices are only very slightly
prominent. The spines on all the trophi are more or less doubly
serrated.

_Cirri._--The three posterior pair are elongated, with their anterior
surfaces not at all protuberant. The segments bear from three to five
pair of spines, with a row of three or four small intermediate spines;
there are, as usual, some little lateral upper rim spines; the dorsal
tufts contain some thick and thin spines mingled. _First_ cirrus is
short, and placed not quite close to the second pair; the basal segments
are broad and thickly paved with bristles. The _second_ pair is rather
short compared with the _third_ pair; a varying number of the basal
segments in both rami of both these cirri are protuberant, and are
thickly paved with bristles; such segments are more numerous and are
broader on the anterior rami than on the posterior rami. In _L. cauta_
alone, none of the basal segments in the posterior rami of the second
and third cirri are thickly paved with bristles. The pedicels of the
first three pair are irregularly covered with spines; those of the three
posterior pair have the spines arranged in a regular double line. Most
of the spines are doubly serrated.

_Caudal Appendages_ (Pl. X, fig. 23 and 24), multiarticulate, with thin
elongated segments fringed with short spines; in length generally
exceeding the pedicel of the sixth cirrus, and in _L. Nicobarica_
equalling half the entire length of this cirrus.

_Stomach_, destitute of caeca; oeso
