NOTE ON SCYLLARTJS SCULPTUS, LATE,. — WHITELEGGE. 161 
about eighteen denticles, including the larger ones situated at the 
inner and outer angles. Second joint twice as broad as long ; the 
superior distal margin bears five spines ; of these, two are situated 
on the outer fourth, one about the middle and two on a produced 
lobe, which projects in front of the basal joint of the first antennse 
and partly conceals the lower third of the second joint. 
Third joint greatly expanded, somewhat cordiform in outline; 
the outer margin is neatly curved, and bears six teeth, each of 
which is minutely denticulated* The distal margin is oblique, and 
has four or five large teeth ; the inner border is tridentate, the 
denticules occur on a projecting lobe similar to, but larger, than 
that on the inner angle of the preceding joint. 
Fourth joint as broad as long, the inner border with three spines 
and the distal margin with two or more ; the outer distal angle is 
produced on the lower surface, but not on the upper. 
Fifth joint nearly one-fourth broader than long ; its outline is 
semi-elliptical ; the margin is shortly ciliate, the inner third is 
acutely dentate, the rest crenate, the surfaces are minutely hairy 
punctate ; the upper surfaces of all the preceding joints are more 
or less scaly or tuberculate. 
First pair of legs stout ; the inferior surfaces of the first three 
joints are beset with elevated tubercles, with dark brown tips ; the 
merus is somewhat compressed, the inner surface is smooth and 
adapted to the carapace, the outer is slightly depressed longitudin- 
ally; near the upper border the latter is subcarinate, smooth, and 
shortly setose ; the inner lower border is similar to the upper, but 
is less elevated and only half its length ; the outer aspect of the 
lower border is marked by a series of ten subspiniform scales ; 
the distal margin has four or five obscure spines. Carpus half as 
long as the merus, with a strongly marked groove on the outer 
surface near the rounded upper border. 
Propodus tapering, its greatest depth equal to half the length, 
its diameter equalling the depth at the distal extremity, the upper 
and lower borders are rounded. Tarsus curved, as long as its 
supporting joint, upper surface somewhat flattened, internal aspect 
grooved, the lower with two tufts of setse near the base ; the 
distal half is horny, the Cornells and calcareous portions overlap 
at their junction, the latter at the sides and the former above 
and below. 
Second pair of legs the longest, their length without the tarsus 
equal to the first and also to the third ; fourth and fifth shorter, 
the latter nearly equal to the first without the tarsus. 
The merus joint of the second pair is one-fourth longer than 
that of the first and of the fourth, about one-eighth longer than 
the third, and nearly twice the length of that of the fifth ; it
