I am unable to find any satisfactory grounds for separating this species from that 
of Professor Mobius. A full description follows, as that of Professor Mobius is scarcely 
sufficient on small points. Body comparatively slender, with the lateral processes 
widely separated and slightly increasing in length to the third, which is directed back¬ 
wards. 
The Cephalon is long, rather broader than the rest of the body, bevelled 
anteriorly to form a median point, immediately behind which lies the stout ocular 
tubercle. This is stout, erect, rounded in front, and terminating in a short spine on 
the posterior half of the tubercle above the eyes. The four eyes are well developed, 
the anterior pair being much the larger. The Ovigers arise on small body-processes 
immediately in front, and rather below the level of the first lateral pair. 
The Abdomen is very long, slightly curved, and with a clavate extremity ; it is 
not articulated to the trunk, and is directed obliquely upwards at a considerable angle. 
It is covered with minute curved spines. 
The segmentation of the trunk is rendered conspicuous by a slightly raised ridge 
forming the posterior border of the segment, these ridges are rather more prominent 
ventrally, and in both cases bear a few minute spines. Similar spines occur on the 
lateral processes, and form a distal fringe round them. 
The Proboscis is movably articulated to the trunk and directed downwards, its 
origin is ventral, and at the proximal end of the cephalon ; it is cylindrical, tapering 
slightly, its distal extremity rounded and the mouth small. It is completely covered 
with minute spines except for a narrow band in the mid-ventral line. 
The Chelifori are well developed, and arise close to the middle line, their origin 
occupying almost the entire width of the cephalon. The scape is two-jointed, and half 
as long as the trunk measured to the base of the abdomen ; the two joints are sub-equal 
in length, the second being expanded distally. The chela is directed downwards, the 
palm rather curved, and fully as long as the other joints. The small dactyii are directed 
inwards, the movable one having a spiuous cushion at the base. The entire appendage 
is covered with minute spines, largest and most numerous on the second joint of the 
scape, the distal fringe of which is also more conspicuous. 
The Palps are stout single-jointed stumps arising from the sides of the cephalon, 
about the middle of its length. 
The Oviger is ten-jointed. The first joint is very short and stout, the second is 
much longer, clavate and setose on its outer margin ; the third is shorter, curved, and-* 
having a very oblique termination ; it is also setose on its outer margin. These three 
joints form a curve in one direction, and the following three curve in another. The 
fourth and fifth joints are comparatively long and sub-equal, both slightly curved, the 
fourth setose on both sides, the fifth only on its outer margin.; the sixth joint is short 
and much curved, and from this one the remaining joints become shorter, more slender, 
and more setose, the setse being longer than elsewhere. There is no terminal claw, nor 
denticulate spines.
