Beskrivelse. Legemet er (se PI. XVI, Fig. 5) lige- 
s ° m bos foregaaende Art noget sammentrykt, og uden nogen 
bydelig dorsal Kjol, idet Ryggen overalt, ogsaa fortil, er 
J'evnt hvselvet. 
Hovedet er omtrent saa langt som de 3 forreste Seg- 
"lenter tilsammen og afsmalnes noget mod Enden, som er

^l )0r af nogen Ivjol.

than twice as long as 1st, yet attaining scarcely half the 
length of body, 3rd joint of peduncle projecting beyond 
point of head; flagellum shorter than peduncle, ten-jointed. 
The 2 anterior pairs of legs — exhibiting usual structure, 
small and feeble. The 2 succeeding pairs have the 2 
last joints about equal in length, terminal claw consider- 
ably shorter than both of these taken together. Basal 
joint of 6th pair of legs with rounded lobe on inner 
side of base. Last pair of legs short and thickset, with 
posterior expansion of basal joint exceedingly large and 
reaching beyond 3rd joint; terminal joint very slender, 
linear. Second pair of caudal stylets remarkably small, 
last pair with comparatively short and almost naked branches. 
Telson rather small, obtuse at extremity, and cleft beyond 
the middle. Colour whitish. Length 8” m . 
Locality. — Stats. 31, 124, 137, 200, 251, 362. 
Remarks. — This comparatively diminutive species 
may be recognized from all previously known forms by 
tlm unusually small antennae, its want of eyes, as also the 
considerable size of the expansion distinguishing the basal 
joint of the last pair of legs posteriorly. 
Description. — The body (see PI. XVI, lig. 5), is 
somewhat compressed, as in the preceding species, and with- 
out any distinct dorsal keel, the back being everywhere — 
also the fore part — uniformly arcuate. 
The head about equals hi length the 3 anterior seg- 
ments tapering a little toward the extremity, which is some- 
what obliquely truncate. Above, it is uniformly arcuate, 
without the slightest trace of a keel. 
The 4 anterior pairs of epimera are comparatively 
smaller than in the preceding species, and have no denti- 
form projection. The 1st pair are somewhat expanded 
below, and evenly rounded off; the 2 succeeding pairs, on 
the other hand, are obtuse at the extremity; the 4th pair 
form posteriorly a sharp, projecting corner. 
The lateral plates of the 3rd abdominal segment are 
not angular posteriorly, like those in the preceding species, 
but drawn out to a narrow, rounded, lingmform lobule. 
The succeeding segment is evenly arched above. 
Eyes, it would appear, entirely absent, as in the pre- 
ceding species. 
The 1st pair of antennae (fig. 5 a) are very small, 
scarcely at all longer than the head and the 2 anterior 
segments taken together. The 1st joint of the peduncle 
is “short but rather stout; the 2nd, on the other hand, 
becomes’ abruptly much longer and more slender; the 3rd, 
as usual, small, and not distinctly separated from the flag- 
ellum. The latter lias about the length of the peduncle, 
and consists of 7 articulations. 
The 2nd pair of antennie (see fig. 5) arc more than 
twice as long as the 1st, without however attaining half 
the length of the body. Of the joints of the peduncle, the 
2 first “as in the preceding species, are entirely concealed;
