156 Nicholls and Bakxes. — Two New Terrestrial Isopodn. 
The seeoiid maxillae (IM. XX, figs. 10, 11) are angularly pro- 
dm-e<l near tlie base. The outer lobe is small and bears apically 
a few s])ines; the inner is rounded and has the inner margin and 
apex fringed with strong spinous setae. 
The maxiilipeds (PL XX, figs. 8, 9) are long and narrow. 
The ei)ipodite is more tlian half the length of the basal joints. 
In the eiidopodite only the iscdiinm is distinct, the other' joints 
being indicated by lobes on the inner margin. The whole of the 
inner margin is fringed with stout setae but externally there 
are only two spines, the ischium, also, bears two spines. The endite 
is narrow and rt'aches more than half way up the endo])odite, its 
inner margin is fringed with setae and apically it bears a long 
curved spine, in addition to a jointed setose lash. 
The j)osterior margins of the first four segments of the meso- 
some are practically straight, those of the last three concave and 
}>roduced backwards at the lateral angles. 
The posterior corners of the first four segments arc sub-quadrato, 
of the fifth rounded, and those of the sixth and seventh sub-acute. 
The cjiimera of ail the segments are well developed. The first 
three bear on the under surface, definite coxopodites in the form 
of raised ridges. 
All the walking legs are similar in structure and increase slightly 
in length posteriorly. The dactylar seta is distinctive in shapo, 
setose, narrow ]>roximally, expanded and thickened distally, and 
has a blunt a]>ex. The first two segments of the metasotne are 
without e])iniera and covered laterally liy the last mesosoniatic 
segment. The e])imera of segments three to five are large, con- 
tiguous and slightly recurved, those of the fifth bordering the 
uropods laterally. The terminal segment is rounded posteriorly, 
very short, convex and mucli broader than long. 
The. uropoda lu-oject beyond tlie terminal segment occupying 
jiractically the Avhole of the sjmee between tlie epimera of the 
fifth segment. The Iiase is broad and rectangular, witli the inner 
distal corner ob]i(]uely cut, the posterior margin crenate and bear- 
ing a number of stout short spines. The outer ramus is spatulate, 
inserted u])on tlie upjier surface near the mesial border, projecting 
posteriorly slightly beyond the base. The a]>ex is armed Avitli » 
number of long setae and a few smaller ones. Tlie inner ramus 
rises from the under surface of the base far forward, is slender 
and scal)rous, the aj)ex ])earing one long bristle and one or two 
smaller ones.
