[No. 2, 
Fumedonus zebra , n. sp. 
Carapace, in spirit, of a yellow colour, and traversed fore-and-aft 
by five broad parallel liver-coloured bands—a median and two lateral: 
the median and the inner lateral band on either side being continued 
a certain distance on to the abdomen. 
The carapace is sharply pentagonal, the antero-lateral angles being 
sharp and directed straight outwards. 
The rostrum forms a long, broad, sub-triangular lamfna bifurcated 
near the tip. 
The chelipeds in the female are about the same length as the cara¬ 
pace : the ischium has a sharp tooth on its inner border, the merus has 
one on its inner and one on its upper margin, the carpus has a very- 
strong one on its upper border, and the hand has two on its upper 
border: the legs have the merus strongly compressed, with the upper 
border dentate or cristate, and the dactyli are strongly recurved. 
Two ovigerous females from off Ceylon, 82 fms : the extreme length 
of the carapace of the larger specimen is 10 millim.

Carapace sub-hexagonal, about as broad as long, with the dorsal 
surface nearly flat, spinose or tuberculated. The spines of the rostrum 
are elongated, acute, and separated by a rather wide interspace, and 
there is a well-developed lateral epibranchial spine. The orbits are 
small and circular, and the sub-ocular lobe joins the front, so as com¬ 
pletely to exclude the antennas from the orbits. The basal joint of the 
antennae is slender and like the greater part of these appendages is 
hidden beneath the front. The external maxillipeds are small, the 
ischium-joint not produced at its antero-internal angle, the merus 
distally truncated, not produced at the antero-external angle, and 
scarcely emarginate at the antero-internal angle, where the next joint 
articulates. The chelipeds are relatively slender and somewhat elon¬ 
gated, with the joints not dilated, the merus and carpus sometimes 
armed with spines ; the dactyli acute and shorter than the palms; the 
ambulatory legs are slender, with the joints not dilated, the merus 
sometimes armed with a distal spine ; the dactyli nearly straight.
