44 T. V. HODGSON. 
LEIONYMPHON MINUS. 
(Plate VI., fig. 2.) 
Specific characters :— 
Body rather robust, with three prominent transverse ridges produced to a point in the mid- 
dorsal line. 
Proboscis shorter than the body, slender, pyriform. 
Palp 9-jointed ; the terminal joint twice as long as any of the preceding four. 
Oviger 10-jointed. In the male the three terminal joints bear an irregular series of stout but 
simple spines. No terminal claws. 
The body is rather robust and the lateral processes are clearly but not very widely 
separated. It measures rather less than 5 mm. in length and less than 4 mm. in 
extreme width. The segmentation is distinct, and the articulations le at the hinder 
part of the three transverse ridges which cross the body. These ridges are strongly 
developed, produced to a point in the middle line, and slightly curved backwards. They 
are equally prominent ventrally, but inflected backwards and not produced into a 
point. The lateral processes are stout, the two anterior being directed forwards at 
slightly different angles, the two posterior ones are similarly directed backwards ; each 
bears dorsally two distinct tubercular processes which are also to be found in a less 
prominent degree on the first coxee. 
The Cephalon is scarcely, if at all, expanded, and its centre is occupied by a very 
stout Ocular tubercle which is directed slightly forwards, and appearing, in certain 
aspects, to be enlarged near its extremity, which bears a very rudimentary spine. The 
four eyes are not particularly well developed. 
The Abdomen is short and stout, not separated from the trunk by an articulation ; 
it is directed obliquely upwards and does not extend as far backwards as the last pair 
of lateral processes. 
The Proboscis is pyriform, slender, and about two-thirds the length of the body, 
to which it is flexibly united. It shows indistinctly three pairs of longitudinal bands 
along the greater part of its length. 
The Chelifori are rudimentary ; the scape is well developed, slightly curved, and 
bears only a few small setze besides the rather promiment distal fringe. The chelze are 
reduced to a knob with the merest traces of fingers. 
The Palps are 9-jointed and rise at the side of the proboscis; the first and third 
joints are quite short and subequal, the second and fourth are also subequal and about 
five times as long; the four following are quite short and subequal, while the terminal 
one is ovoid and twice as long as any of the preceding four. The fourth jomt bears a 
small distal fringe, but otherwise there are practically no setz on the first four joints ; 
the following four joints are very considerably dilated ventrally, and this enlargement 
bears a dense tuft of small stiff sete. The terminal joint is more extensively covered 
with sete, especially on its ventral side. 
The Ovigers are 10-jointed and rise ventrally just in Row of the first lateral
