MALE. The only specimen is 19 mm. in length and a trifle narrower; compared 
with the female represented, it is tolerably large (fig. 3b : fig. 3a), but only of medium size 
compared with the largest female. Seen from below (fig. 3f), the body is nearly pentagonal; 
the anterior outline, which only in its middle part is formed by the slightly curving frontal 
margin, but towards the sides of parts belonging to a lower level, is but feebly curved and 
comparatively broad, the lateral angles are obtuse, but the posterior margin of the body 
forms a rather broad curve. The head is somewhat larger than the trunk. The afore- 
mentioned, scarcely produced frontal border has a fringe of hairs. The antennule are slender, 
of medium length and provided with long sete. The antennz and the maxillule much as in 
the female; the mouth smaller than in the latter. The maxilla have a distinct conical 
process on the posterior side of the basal joimt. The basal joint of the maxillipeds has a 
sinuate inner margin, its outer surface is supplied with hairs, and its anterior side has two 
transverse rows of tolerably long hairs; the last joint ends in three points of unequal length. 
In the sub-median skeleton are only found the two first pairs of processes; the first pair 
which are situated behind the mavxille, are broad, somewhat produced and rounded, the 
second pair which are situated between the maxillipeds, are scarcely of medium length and 
feebly diverging. The lateral margin of the head fringed with long hairs, and the ear- 
shaped arch round the base of the antennule distinguishes itself particularly by its very 
long hairs. The stripe of hairs which proceeds from near the posterior angle of the lateral 
margin, running upward across the side and the back, is somewhat more oblique than in 
S. Holbélli, and its hairs are somewhat shorter, otherwise the hair-covering of the trunk and 
its dorsal, naked transverse area are much as in this species, and the same resemblance 
appears in the empty spaces beneath the skin of the head. The first pair of legs consist of 
a very broad and rather long, hairy basal part, from which proceeds a single moderately 
long branch, which terminates in a single seta of the length of the whole leg or of the first 
joint of the maxillipeds. The second pair of legs entirely like those of the former species, 
the only terminal seta of the inner branch about the length of that of the first pair of legs. 
The very thick caudal stylets have a terminal seta which is scarcely as long as that of the 
second pair of legs. 
OVISACS. They differ very much in size, even if not containing larvae. Of ten 
ovisacs belonging to the same female the smallest one is globular and has a diameter of 
30 min., the largest (represented in fig. 3c), is ‘53mm. long and 43mm. broad. In another 
female was found a still larger ovisac which is ‘64 mm. in length and 49 mn. in breadth. 
So these oyisacs are large compared with the females, and the eggs themselves are large 
and not numerous. 
LARVA. I have found two ovisacs containing larve which were serviceable, yet 
not quite capable of swimming away, and these specimens have served as models for fig. 3h. 
A list curving somewhat like an S is seen inside the anterior angle of the antennula. The 
olfactory seta of the 2-jointed antennuke is long, a little shorter than the cephalothorax.
