ig. 1.
Carapace more than twice as wide as long; the sides in front extended
into a long slightly bent spine. The frontal portion between the pedicles
of the eyes is narrow, much as in Macrophthalmus, it slopes down towards
the mouth, and is deeply notched at the sides for the reception of the
eyes; the fore-edge is doubly notched in the middle, there being a slight
tooth between the emarginations. The epistome not so prominent as the
lower margin of the orbit; the inner antennae, with the basal joint, long
(the others broken off). The eye-pedicles very long and cylindrical,
thickest at the base, slightly bent, somewhat thickened towards the end,
so long, that, when bent back, the eye extends a little beyond the end of
the spine. Mouth formed nearly as in Gonoplax, the third joint of the
jaw-feet wider than long. Abdomen seven-jointed, the first joint scarcely
visible, shaped much as in Gonoplax, but rather wider, the base of the
terminal joint longer than the sides. Anterior legs two and a half times
as long as the Carapace, measuring it from spine to spine, the arm long
and triangular, the upper portion more or less thickly covered with small
papillae, and having a nearly obliterated spine about the middle; the
wrist smooth, roundish, with a large blunt tooth on the inside; hands
somewhat flattened, widest at the base of the claws, with a broad ridge
on the inside, the edge of it rough with small papillae; the upper edge
of hand rough with small papillae; the claws lap over each other at the
tips, and are irregularly toothed on the inside; the fixed claw of the
right hand bent at the base, so as to leave a considerable space when the
other is closed upon it; upper part of arm, hand, and movable claw pretty
thickly spotted with red, epistome orbits and greater part of the upper
surface of carapace spotted with red, sides and hind part of carapace
white; upper edge of the orbit covered with small papillae; a tolerably
prominent ridge extends across the carapace before the middle. Four hind
pairs of legs long, slender, compressed, the upper edges of the second
and third pairs fringed with hairs, as well as the lower edge of the two
terminal joints, the claws long, thin, and somewhat bent.
Habitat: Port Curtis. Shoal water, mudbanks.
This fine Crustacean is allied to Gonoplax and Curtonotus; and being one
of the most prominent species sent home by Mr. Macgillivray, is selected
for description here; the figure is of th
