Posterior antennae with Ri much longer than Re, the former with six long bristles 
on the first segment, and seven and six bristles on the distal segment. Re very 
indistinctly segmented, the proximal joint very elongated. 
Mandibles with Ri longer than Re, B 2 with one marginal bristle, masticatory 
plate broad, with one rather large tooth and a good space between it and the next 
five conical short teeth. 
Maxilla with B 2 and Ri bent outwards ; B 2, Ri, and Re coalesced and almost 
indistinguishable; Li 1 with seven rather long and stout hooks and two shorter 
bristles; Li 2 a large lobe with three bristles, Li 2 with one bristle; Ri indistinctly 
segmented on the outer margin with five apical bristles ; Re scarcely segmented, with 
only two bristles; Le 1 with seven long and very thick bristles, and three shorter 
bristles. 
Anterior foot jaws with lobes much compressed, and terminal five bristles longer 
than the proximal and also much thicker. 
Posterior foot jaw very similar to that of Anomalocera. B 2 is short, but rather 
thick, and with one short bristle ; Ri short, unsegmented, with only three terminal 
and short bristles. 
One to four pairs of feet, with Ri of only two, Lie of three segments. In the first 
pair the external marginal setae of Re are long and thin, in the others the external 
spines are short, and in all there is only one marginal spine (apical) on Re 3. 
First pair of feet, B 1 and B 2 with only slightly convex inner margin and no Si. 
Re 1 longer than Re 2 + Re 3, outside margin haired and long marginal bristle. Re 2 
and Re 3 with similarly long marginal bristles. Se — 1:1:2 and Si = 1:1: 5. Ri 2 
nearly twice as long as Ri 1 and with 5 Si. 
In the second pair B 2 is broader than long, the inner margin convex and without 
hairs or bristles ; B 1 is also without Si. Ri 1 prolonged, Ri 2 shorter (as 7 : 1 0). Ri 1 
with 2 Si, Ri 2 with 7 Si. 
1A 1:2:3 as 11:6:9, with respectively 1:1:1: Se, that of Re 1 the largest and 
of Re 3 the smallest; the end saw about two-thirds as long as the whole Re ; a small 
curved spine distal margin of Re 3 just external to the saw. 5 Si on Re 3. 
3rd feet. B 1 and B 2 without bristles or hairs, Ri as in the preceding pair, Re 
as in the preceding pair and with 1 : 1 : 1 Se only. 
4tli feet. B 1 and B 2 as before. Ri 1 with three Si, Ri 2 with only six Si. The 
three joints of Re rather more equal in length, Se 1 : 1 : 1 as in the other feet. Ri 1 is 
more elongated than in the other feet and twice as long as Ri 2. 
In the second to fourth pairs the Ri is more than half as long as the Re and 
extends beyond the distal margin of Re 2. In all feet the number of external marginal 
spines is certainly peculiar, the usual rule being three marginal spines on the Re 3, so 
that the animal differs from any true Labidocera. 
The 5th feet consist of a common basal and one ramus on each side of two 
segments B 2 and Re, Ri represented only by a spine. The first and second basals are
