than that of the second pair of appendages, and is bent 
like an elbow on its outer posterior side. The free end of this 
endite 1s provided also with greater number of blunt spines 
compared with that of the succeeding pair of appendages. The 
terminal portion ofthe sixth endite is not pointed, but cut abrup- 
iv. The third pair ofappendages hasits sixth endite rather small, 
wilhe the finger-shaped terminal projection of the fifth endite 
is very large, projecting far beyond the sixth. The tip of this 
projection 1s beset with numerous (about 30) sensory setae. This 
projection becomes gradually smaller in the succeeding pairs of 
appendages Ull to twelfth where it completely disappears. 
Of all the endites, the first only remains till to the last appen- 
dages, while all the rest gradually disappears, and theflage lum : 
is only represented by à small projection with two selae, one 
of which is {wo jointed. The branchiae the twenty-fourth appen- 
dage is also seen as à slight projection at the base of the fla- 
bellum. The postabdomen (fig. 22, e) with about thirty pairs 
of coarse teeth of unequal length on the upper side, the first 
being the largest. AIT the teeth as well as the terminal spine 
finely serrated. The first spine is curved backward and is ser- 
rated on its posterior concave side, while the surration of the 
terminal spine is on the upper concave side. The caudal appen- 
dage nearly three times as long as the terminal spine, provided 
with about six feathered setae an the upper inner side of its 
basal third, and with à finely serrated spine at the point one- 
third from its base to the tip and in the same line with feathe- 
red setae, while the dorsal posterior half of the appendage 1s 
also finely serrated Ull to à short distance from its terminal 
end. » 
«In the Female the first antennae are relatively a little shor- 
ter, the sense-setae less developped, the second antennae with 
fifteen Joints onu the upper flagellum and with sixteen on the 
lower. The finger-shaped terminal projection of the fifth endite 
of the first leg relatively shorter, that of the first being smaller 
than the sixth endite, and provided with about fifteen sensory 
setae on the Up ofit, and is found till to the ninth appendage, 
the entire number of this projection being thus equal in both 
the sexes. The branchia exists Gill to the twenty-third appen-
