sete; the other stylet is wanting; the whole area is naked. (In fig. 6e to the front the 
two receptacula seminis are indicated by dotted lines). 
MALE. The only specimen found is tolerably large in proportion to the female 
(fig. Gb: fig. 6a); it is 21mm. in length, but on account of pressure it is somewhat crooked, so 
that the normal shape of its body cannot be precisely determined. The frontal border is rather 
considerably produced, its margin very long, somewhat emarginate in the middle and forming 
on each side of this inward curve a gently convex margin, which on its upper, as well as its 
lower side, is! provided with a narrow border of numerous short (in the drawing a little 
too short) setaceous processes; further, across the lower side of the front a little in advance 
of the rostrum, runs a long, straight, very narrow list, which almost reaches the lateral 
margin, and which is armed with a series of very small conical processes. Antennule 
small, terminating in a setaceous point and with only a single, moderately long seta, which 
no doubt is olfactory. Antenne wanting. Mouth-border with long hairs. Anterior principal 
branch of the maxillule developed only as a somewhat protruding rounded corner; the hindmost 
principal branch extremely short, tap-shaped; additional branch wanting. Maxille small, 
all three joints entirely fused together, with no vestige of articulation, but the general 
outline of the maxilla nearly as in S. dispar, however, its distal part is very slender and 
terminates in a point. Basal joint of the maxillipeds a little more than medium length, not 
swollen, smooth; on its anterior side near the apex it has a large process, the basis of which 
is constricted, while the remaining part forms an oval knot parallel with the outline of the 
joint; second and third joints are fused into a single short joint with a short and broad 
terminal seta, whereas the last joint is very short, broad and flattened, with denticulated 
terminal margin. Nearly on a line with the anterior angle of the base of the maxilipeds 
are seen, close to each other, two small, short, conical processes, whereas other processes 
are wanting; but inside of and behind the posterior angle of the maxillipeds are found 
peculiarly shaped lists. The lateral margin of the head developed as in the two preceding 
species; from the base of the antennula it is furnished with rather long hairs, and from 
the posterior angle of the margin, as far as I have been able to see, the boundary of the 
hairy part runs upward and somewhat obliquely backward across the side and the back. 
The trunk, on its back, its sides and the posterior half of its ventral surface, is covered 
with long hairs; the anterior half of its ventral surface is naked. Trunk-legs and caudal 
stylets wanting. 
OVISACS. ‘Those that have been found are rather small (fig. 6c), yet, as each of 
them contains six or seven nearly or fully developed larvie, they must be considerably larger 
than when they were laid. The ovisac represented is 34 mm. in length and -27 mm. in 
breadth. 
LARVA. Though very similar to those of the nearest preceding species, it presents 
various good characters (fig. 6g). Length of the body ab. 21mm. The cephalothorax is 
an oblong oval, a little narrower than in the two last-mentioned species. The front has a
