SPOLIA ZEYLANICA. 
antennae unsymmetrical, the first antennae of the female being 
so to a conspicuous degree, the second of the male having several 
more joints in the flagellum of one antenna than in that of the 
other. 
The frontal lamina surmounting the epistome is pentagonal. 
The upper lip and mandibles do not sensibly differ from those of 
Cirolana pleonastica .* The first maxillae have the usual three 
plumose setae on the inner plate, the inner margin of which has a 
small projection. As shown by the figures, in the male the fourth 
joint of the maxillipeds is a little narrower than the fifth, whereas 
in the female it is a little broader. The vibratory lamina of the 
second joint in the female is of considerable size, of much greater 
length than breadth. 
The first gnathopods are short and stout, the fourth joint 
fringed with six spines, which look as if worn down by use ; the 
fifth joint is almost completely overlapped by the fourth ; the 
sixth joint is characterized by a projection of the distal part of the 
inner margin, which carries two spines and some setules. 
The second gnathopods have four spines on the inner margin 
of the third joint, eight or nine on that of the fourth, which also 
has an oblique row of spines on the distal part of the inner surface. 
The perseopods are furnished with strong spines on the distal 
and inner margins of the third, fourth, and fifth joints, some but 
not all of these spines having the multifid structure noted by 
Schiodte and Meinert and by H. J. Hansen in some species of 
Gorallana and Excorallana. 
In the second pleopods of the male the masculine appendage 
is apicallv acute, reaching scarcely beyond the rami. 
The uropods have the inner branch apically broad, rounded, 
serrate, with twelve spines in the serrations and numerous hairs, a 
longer tuft occupying one serration which has no spine. The 
much narrower outer branch has eight or nine spines on the outer 
margin, four or five on the inner, and a spine-like apex. This also 
is setose. 
A specimen flattened out measured 8*75 mm. The colour in 
spirit is dark brown upon light, forming generally a symmetrical 
pattern, of which the darkest portion is in the dorsal centre of the 
fourth to the sixth pera3on segments, to which follows a light 
piece shaped like a spearhead and reaching with its point to the 
base of the telsonic segment. 
The species is named out of respect to the discoverer, Dr. 
Arthur Willey. From Cirolana sculpta , Milne-Edwards, found on 
the coast of Malabar, the present form is distinguished by having
