the sides and the posterior part of the animal are very closely covered with tiny dots which 
resemble the base of fine hairs, yet no such hairs could be seen. From the outer angle of 
the first pair of legs this curious area is crossed by a narrow naked stripe which runs 
upward in an oblique direction and somewhat backward across the side and the back (fig. 31); 
the ventral surface of the trunk between the legs and the caudal stylets is covered with 
moderately long hairs. The first pair of legs are good-sized, with a broad basal part and 
both branches well developed; the inner branch, which is a little shorter than the outer one, 
is pointed, the outer branch is blunt, terminating in two sete, one of which is plumose and 
double the length of the branch. The second pair of legs about as long as, or a little 
shorter than, the outer branch of the first pair, having near its base a short conical outer 
branch with a short terminal seta, whereas the terminal seta of the inner branch is still 
longer than that of the outer branch of the first pair of legs. The caudal stylets of mode- 
rate length, terminating in some sete, the longest of which is only a little longer than 
the stylet. 
OVISACS. Globular or oval (fig. 3c) and rather small in proportion to the adult 
female (fig. 3a); the eggs in each ovisac comparatively small and pretty numerous. 
LARVA. The length of a free specimen (fig. 3k) 24 mm. The cephalothorax ovate. 
The front (fig. 31) has an oblique list inside the anterior angle of each antenmnula; this 
appendage is 2-jointed, its olfactory seta reaching somewhat beyond the middle of the 
cephalothorax, and being somewhat more than double the length of the antennula. The 
antenne a little shorter than the antennule, 3-jointed, first and second joints of equal length, 
the third joint short, provided with a terminal seta which is of equal length to, or longer 
than, the two last joints combined. The maxillule each with four branches, the foremost 
and inner one of which is rather short, the three others long and powerful, the hindmost 
bending backward and distinctly plumose. The maxille normal, with smooth joints. The 
second joint of the mavxillipeds slightly longer than the third one, the fourth joint with a 
few setz inside the apex. The thick seta at the posterior angle of the first abdominal 
segment reaches somewhat beyond the extremity of the caudal stylets; the third segment is 
very short, and the caudal stylets more or less distinctly set off, their terminal seta being 
about as long as the cephalothorax. 
POST-LARVAL DEVELOPMENT. Unknown. 
HABITAT. The marsupium of Calliopius leviusculus (Kr.) from the East coast of 
Asia between lat. 40° N. and lat. 51° N. In a large material were found altogether seven 
specimens infested with parasites. One specimen is from »lat. 40° N., long. 134° E., Capt. 
Andréa, 1869«; in its marsupium were found two moderately small females, the smallest 
male found, no ovisacs, but numerous — about thirty-three — free larve. Three specimens 
are from »lat. 45° 40’ N., long. 139° E., Andréa, 1869«; in the largest of them were found 
six females, two males and twenty-five ovisacs, in the second specimen four females and six 
ovisacs, in the third three females, twenty-four ovisacs and at least two males (the host has
