Nicholls and Barnes — .1 Xeiv Terrestrial Isopoct.

1 pair, but less sub-eliolate, each slightly longer than the preceding. 
I The spines on the propod, carpus and nierus are more scattered. 
The fifth pair of legs (Fig. H, 5) is longer than the fourth, and 
intermediate in character between those of the anterior group and 
the folloAving. 
The sixth and seventh pairs (Fig. 3, 6) are similar in shape, tlie 
seventh longer than the sixth, l>oth distincdly longer and stouter 
than the fiftli ])air. The spines are more s]>arse. The ischium 
bears a nund)er of fine setae on its anterior border. 
The first pair of pJeopods in the male (PI. X, Fig. 9) has the 
usual structure, the exo])ods delicate and slightly rounded, with no 
suggestion of setae. The endopod is modified, broad at the base 
and tapering to the apex, grooved on the inner margin. The 
endopods are approximately twice the length of the exopods. The 
male organ is single and tapering, reaching to the ends of the 
exopods. 
In the second pair of pleopods (PI. X, Fig. 10) the exopods 
differ from those of the first pair, being longer and broader, and 
pointed at their apices. The inner margin is fringed with fine 
setae, which increase in length posteriorly. The outer margin 
bears a few spinous setae together witli numerous hue setae. The 
slender endopods extend beyond the exopods and taper to a line 
point. 
The third, fourth, and fifth' pairs of pleopods (PI. X, Fig. 11, 
12, 13) are similar in shape, l)ut become gradually smaller. The 
exopods are more or less pear-shaped with their inner margins 
fringed with fine setae, the outer bearing a number of long and 
stout spine-like setae interspersed with finer setae. The endopods 
are moderately developed, irregular in shape, and have the usual 
branchial function. 
In all of the pleopods the peduncles are well develoj)ed. 
In the uropods (PI. X, Fig. 14) the basal joint is roughly 
quadrilateral in shape, almost as broad as long. The outer ramuo 
is three sided and pointed, grooved externally. Apically it bears 
a numbei- of long, fine setae. The inner ramus ta])ers to a point, is 
slightly flattened on one side and grooved as in the outer ramus. 
It is inserted only slightly anteriorly to the outer and is more 
than half the length of the latter.
