considerably shorter than 1st, in male more powerfully 
developed, having 3rd and 4th joints of peduncle lamelli- 
form-dilatod with exceedingly mobile articulations. First 
pair of legs powerful in structure, having hand, in female, 
of normal appearance, in male greatly expanded and comp- 
ressed, with 2 deep incurvations on lower margin and 
terminal claw remarkably long and falciform. Second pair 
of legs much feebler, with hand narrow and somewhat 
longer than preceding joint, as also vertically truncate at 
extremity. Remaining legs slender and elongate, all with 
a narrow, linear basal joint; the 2 posterior pairs con- 
siderably longer than the rest. Last pair of caudal stylets 
very small, with basal part lamelliform, jutting inward as 
an acute-pointed lappet; terminal joint very small, oval.

Locality. — Stats. 18, 31, 124, 137, 200, 290, 312. 
Remarks. — The present species bears closest re- 
semblance to U. planipes Norman, but is easily recognized 
bv its greater size and the peculiar lamellar form of the 
3rd and 4th joints of the 2nd pair of antenna) in the male, 
as also by the structure of the 1st pair of legs. The 2nd 
pair of legs differs in the two sexes from those of U. pla- 
nipes, the hand occurring vertically truncate at the extre- 
mity arid with a well-defined palmar margin. 
Description. - The body (see PI. XVII, figs. 5, 5 x) 
is slender and somewhat depressed, as in the other species 
of the genus, with very small epimera. 
The head occurs truncate anteriorly, without exhibiting 
anv distinctly prominent rostrum. The lateral corners are 
sharply pointed, and, behind them, the lower borders of 
the head constitute an even emargination above the bases of 
he 2nd pair of antenme. ' 
Of the epimera, the 4 anterior pairs are but little 
ar „er than the 3 posterior, and form anteriorly a sharp 
; o rn er which, on the 1st pair, is drawn out to a torward- 
lirected, mucroniform process. The lateral plates ot the 
} anterior abdominal segments form posteriorly an acute- 
.ointed corner, which, more particularly on the 3rd segment, 
s very considerably produced. , . , 
Of eyes, no trace could be detected in the recently 
taken specimens. 
The 1st pair of antennse are slender and elongate, 
eonsidemhly exceeding half the body in length. Of the 
joints of the peduncle, the 2ml is longest, the did on 
he other hand, being remarkably short, scarce one-third 
the length of the 2nd. The flagellum and peduncle are 
well-nigh equally long, and composed of close upon 20 ar- 
ticulations. -The secondary flagellum (see fig. 5 a) is 
very small, scarcely more than half the length of the last 
articulation of the peduncle, - and two-jointed 
The 2nd pair of antenme are considerably shorter 
than the 1st, but relatively more powerful in structure, 
Htf, rather a short nine-jointed flagellum. In the female
