holdsvis betydelig mindre og mere jevnt afrundede. 4de 
og 5te Segments Epimerer er rettede skraat bagtil og ender 
med et kort tandformigt Premspring. 
0inene er sasrdeles smaa og drnkkes for en stor Del 
af Paudepladen. De er af smalt kolledannet Form, med 
den ydre Del kun svagt udvidet og jevnt tilrundet. 0ie- 
pigmentet er ganske lyst, naesten kridthvidt og Synselemen- 
terne kun ufuldkommet udviklede. 
Folerne er ligesom bos Crangonineme naesten fcestede 
i samme horizontale Plan, bvorfor de, naar Dyret sees i 
Profil (Fig. 2), for en stor Del gjensidig dsekker hinauden. 
lste Par Foleres Skaft (se Fig. 3) er temmelig kort, 
neppe halvt saa langt som Rygskjoldet. At dots 3 Led er 
det lstc stox'st, og af samme Lamgde som de 2 ovrige til- 
samrnen. Det er ved Basis paa den ydre Side forsynet 
med den ssedvanlige pladeformige Fortsats, der dog kun er 
lidet udviklet og af smal lancetdannet Form. Den indre 
Kant af Leddet er besat med korte Burster og har noget 
ioran Midten et meget lidet tandformigt Fremspriug. Sidste 
Led er noget kortere end 2det og i Enden tvsert afskaaret. 
Af de 2 Svober er den ydre bos Hannen omtrent dobbelt 
saa lang som Skaftet, lios Hunnen noget kortere; den er 
hos beggo Kjon cylindrisk og temmelig jevnt tyk lige til 
Spidsen som er udtrukken i en kort Endesnamt, samt sam- 
niensat af talrige korte Led, besatte med de ssedvanlige 
Knipper af klare, baandformige Sandseborster. Den indre 
Svobe er (se Fig. 1 og 2) stserkt forlsenget, omtrent 3 Gauge 
saa lang som den ydre, og afsmalnes jevnt mod Enden. 
2det Par Folere (se Fig. 4) bar en kort og tyk, 
utydelig segmenteret Koddel, der saagodtsom ganske er ube- 
da-kket af Rygskjoldet og udad springer frem i Form af 
en stserk trekantet Fortsats. 
Det bladdannede Vedhseng er af en ganske ussedvanlig 
Storrelse og saa stserkt udbredt mod Enden, at det i sin 
normale Stilling ikke blot mpder det tilsvarende paa den 
anden Side, men ogsaa krydser samme (se Fig. 1). Af 
Form er det nsesten trekantet, med den storste Brede, der 
er betydelig storre end den lialve Lamgde, i dets yderste 
Del. Enderanden er nrosten tvsert afskaaret og viser istedet- 
for de ssedvanlige Randborster kun en yderst fin Ciliering. 
Den indre Kant er ganske svagt buet og forsynet med de 
ssedvanlige cilierede Randborster, der dog kun er lidet ud- 
viklede og liurtigt aftagende i Laengde mod det indre at- 
rundede Hjorne af Bladet. Den ydre Kant er nsesten lige 
og ganske glat samt gaar fortil ud i en tandformig Fortsats, 
der er tset trykket til Bladet og overrages af Enderanden. 
Tvsers over Bladet lob or i diagonal Retning en stump Kjol, 
der lidt efter lidt taber sig mod det indre Hjorne. 
succeeding epimera (see fig. 2). In the males, these epimera, 
are, however, comparatively much smaller and more evenly 
rounded. The epimera of the 4th and 5th segments are 
directed obliquely, in a posterior direction, and terminate 
with a short dentiform process. 
The eyes are extremely small, and covered to a great 
extent by the frontal plate. They are narrow and clavate 
in shape, with the outer portion but slightly dilated and 
uniformly rounded. The ocular pigment is quite light, 
approximating a chalky white, and the visual elements are 
imperfectly developed. 
As with the Crangonians, the antennae are attached 
almost in the same horizontal plane; and hence, when the 
animal is viewed in profile (fig. 2), they cover each other 
to a great extent. 
The peduncle of the 1st pair of antennae (see fig. 3) 
is rather short, scarcely half as long as the carapax. Of 
its 3 articulations, the 1st is the largest, equalling in length 
both the others taken together. At its base, it is provided 
on the exterior side with the usual lamelliform projection, 
which, however, occurs hut slightly developed and narrow- 
lanceolate in shape. The inner edge of the articulation is 
beset with short bristles, and exhibits, a little anterior to 
the middle, an exceedingly small dentiform probation. The 
terminal articulation is somewhat shorter than the 2nd, and 
truncate at the extremity. Of the 2 flagella, the exterior, 
in the male, is about twice as long as the peduncle, — in the 
female somewhat shorter; in both sexes it is cylindric in 
form, and nearly of a uniform thickness to the extremity, 
which is produced to a short terminal lash, as also com- 
posed of numerous short articulations, beset with the usual 
fascicles of translucent, riband-shaped sensory bristles. The 
inner flagellum (see figs. 1, 2) is considerably elongated, 
being about three times the length of the outer, and tapering 
gradually toward the extremity. 
The 2nd pair of antennse (see fig. 4) have a short and 
thick, indistinctly segmented basal portion, left well-nigh 
wholly uncovered by the carapax. and, externally, jutting 
forth in the form of a strong, triangular projection. 
The squamiform appendage attains quite a remarkable 
size, and is, toward the extermity, so considerably expanded 
that, in its usual position, it not only meets the corresponding 
appendage on the opposite side, but even overlaps it (see 
fig. 1). In form it is almost triangular, with the exterior 
portion broadest; its greatest breadth considerably exceeds 
half the length. The terminal border is well-nigh truncate, 
and exhibits, in place of the marginal bristles usually ob- 
served, an exceedingly fine clothing of hairs. The inner 
inargiu is very slightly curved, and furnished with the usual 
ciliated marginal bristles, which, however, are but little 
developed and rapidly diminish in length toward the inner 
rounded corner of the scale. The outer margin is almost 
straight and perfectly smooth ; moreover, it extends anteriorly 
as a dentiform projection, closely pressed up to the scale 
and overlapped by the terminal border. Straight across the 
scale, extends diagonally an obtuse carina, which gradually 
disappears toward the inner corner.
