margins with small acute spinules. The dactylopodite and pro- 
podite of the left leg of the third pair are somewhat flattened on 
their outer surfaces. The legs are clothed with yellowish hairs. 
The spinules which are found on the legs are all of a yellowish- _ 
white colour, similar to the spots with which the legs are covered. 
Otherwise the legs are smooth and shining. 
141. CrrBanaRrius ARETHUSA *, n. sp. 
A female specimen was collected in King Island Bay. This 
species belongs, like the three preceding, to that section of the 
genus in which the dactylopodites of the second and third legs 
appear to be shorter, or scarcely as long, but never longer than 
the propodites, when seen from above; and it is most closely 
allied to C. carnifex, Heller, from the Red Sea, and to the form 
which I have described above as C. equabilis, var. merguiensis. 
This specimen is nearly twice as large as the specimens of C. 
equabilis, var. merguiensis. As regards the shape and the struc- 
ture of the cephalothorax and of the postabdomen, C. Arethusa 
closely agrees with that species; but the gastric region is more 
sparsely and a little less coarsely punctate; the anterior part of 
the upper surface of the cephalothorax, which lies before the 
cervical suture, presents some small transverse tufts of rather 
short yellow hairs except in the middle, and some similar small 
transverse tufts are also observed immediately behind the cervical 
suture. The form of the anterior margin of the cephalothorax is 
completely similar to that of C. equabilis, var. merguiensis, the 
triangular, acute, median tooth projecting a little more forwards 
than tne lateral frontal teeth. The median frontal tooth presents - 
no short ridge above, directed backwards, as in Heller’s C. car- 
nifex. The slender eye- peduncles are distinctly longer than the 
anterior breadth of the cephalothorax ; they are also much longer 
than the peduncles of the external antenne, and quite as long as 
the peduncles of the ilaternal antenne. The somewhat hairy 
ophthalmic scales are very small, narrow, triangular, and armed 
with two or three small teeth at their tips; they are compara- 
tively smaller than those of C. equabilis, var. merqguiensis, and are 
more distant from one another. The external antenne are 
similar to those of C. carnifex and C. equabilis; the aciculum 
with which the penultimate joint of their peduncle is armed at 
* Arethusa, one of the Hesperids.
