SPOLIA ZEYLANICA. 
in respect to the last four segments, densely fringed with long 
hairs which assist in retaining the very numerous eggs. The 
second antennae are tipped with an elongate seta. 
The first maxillipeds have the little process which De Haan 
appears to be describing in regard to his genera Trichopus 
(= Varuna) and Eriocheir by the words, in the first case, “lacinise 
externae lamella ex medio margine interiore producta, neque 
transversa, auctae,” and in the second with omission of the word 
“ medio ” and substitution of “ ovata ” for “ neque transversa.” 
In modern language this would be interpreted as a reduction 
of “ the endopodite to a minute projection of the inner margin of 
the exopodite.” The second maxillipeds have the penultimate 
joint densely lined with long setae. The third pair have the 
peduncle of the exopod large, but not as broad as the third joint 
of the main stem. This in turn is neither so wide nor so long as 
the great fourth joint, which has the fifth joint inserted at the 
middle of its broad apical margin. 
The chelipeds (or first peraeopods) are;very large in the male, 
subequal, with the inner distal margin of the wrist finely serrate, 
the hand very bulky, the thumb having two rows of fine denticles 
along its inner margin, receiving at its broad apex the point of 
the movable finger, which is similarly serrate, but also has a 
prominent stout tooth near the base. There is a large gap 
between the closed finger and thumb. In the female the chelipeds 
are quite small, and the small thumb and finger close their 
straight margins together without a gap. The second peraeopods 
have the last four joints densely setose on the inner surface towards 
the outer margin, and the first of these joints furnished with 
unequal teeth or spines about the inner margin, the apex of which 
is acute in the wrist. The fifth peraeopods are rather smaller 
than the three preceding pairs, but similarly hirsute. 
The larger of the two male specimens was 7*4 mm. broad at 
the widest part of the carapace and 5*25 mm. long at the centre 
of it. The two females were both laden with eggs. In this sex 
the carapace was as long as that of the male, but not quite so broad. 
The specific name alludes to the part taken by this little species 
in the group of crustaceans here under discussion.
