12 T. V. HODGSON. 



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 dactyli are directed 

 inwards, the movable one having a spinous 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 setae being longer than elsewhere. There is no terminal claw, nor 

 denticulate spines.
