Sp. unica. _Amorphopus cylindraceus_, mihi.
_Description._--The body is nearly cylindrical, somewhat depressed, the
carapace very much curved from the point to the back, quite straight
from side to side; the anterior and lateral margins forming nearly a
semicircle, the posterior margin straight; the orbits are deeply cut in
the anterior margin of the carapace, looking upwards; the inferior
margin wanting; the oral aperture much arched anteriorly; the external
footjaws with the third articulation somewhat rhomboid, the fourth
irregularly oval, and the palpi three-jointed, inserted at its anterior
and inner angle. Epistome extremely small, transversely linear; the
external antennæ placed directly beneath the orbits, the basal joints
partly filling them beneath. The antennules folded transversely in large
open fossæ, which are scarcely at all separated from each other, and are
open to the orbits, the eyes lying transversely; the peduncles short and
thick; the sternum is semicircular, the segments separated by very deep
grooves; the abdomen very long and narrow, the first and second joint
transversely linear, the third and fourth united and forming a triangle
truncated anteriorly at the articulation of the portion formed by the
fifth and sixth joints united, and which with the seventh form a very
narrow and linear piece extending forwards to the posterior margin of
the oral aperture; the first pair of legs robust, unequal (the right
being the larger in the only specimen at present observed); the hand in
each as broad as it is long; that of the smaller conspicuously
tuberculated, that of the larger much less so; the former with the
fingers nearly meeting throughout their length, those of the latter only
at the tips; the second, third, and fourth pairs of legs are long,
somewhat compressed, the third joint tuberculated on the under side, the
third pair the longest; the fifth pair is reduced to a mere rudiment, in
the form of a minute tubercle inserted in a little notch at the base of
the first joint of the fourth pair, and scarcely discernible by the
naked eye.
_Observations._--The relation of this genus to the Pinnotheridæ is
tolerably obvious, in the smallness of the antennæ, the direction and
arrangement of the eyes, and particularly in the form of the oral
aperture, and of the external footjaws. I shall not, however, enter upon
the consideration of these relations, as I am about shortly to offer to
the Society a review and monograph of the whole of this family. The most
remarkable peculiarity in the genus is the apparent absence of the fifth
pair of legs, which can only be discovered to exist at all by
examination with the help of a lens. In this respect I doubt not that
the Fabrician genus _Hexapus_, adopted and figured by De Haan, will be
found to agree with it, although it is very remarkable that the
anomalous condition of this part never excited any particular attention
on the part of either of these distinguished naturalists; and De Haan
describes Fabricius's species, _Hexapus sexpes_, as if there were
nothing especial or abnormal in a Decapod having only six pairs of legs
besides the claws. Mr. White made a similar mistake on one occasion,
when he described an anomourous genus allied to _Lithodes_, in which the
fifth pair of legs were not visible; but when, at my suggestion, a more
careful examination was made, they were found, as was anticipated, in a
rudimentary form, concealed under the edge of the carapace. I believe
that I can discover even in De Haan's figure something like a little
tubercle at the base of the fourth leg, which is probably the
rudimentary representative of the fifth.
