Bemserkninger. Da Skegten for Tiden kun er re- 
prsesenteret af den her omhandlede Art, bliver det selv- 
folgelig vanskeligt med Bestemthed at angive de Charac- 
terer, der skal tillmgges specifisk Yaerdi. Hos Slaegten 
Janira, som kommer denne Slmgt mermest, synes imidlertid 
Hovedets og Bagkroppeus Form saint Forholdet af Epi- 
merernes Bevaebning at va*re af storst Betydnig i denne 
Henseende, og jeg har derfor ogsaa troet her at maatte 
opfore disse Characterer som Artskjendenian'ker for nser- 
vserende Form. 
Beskrivelse af Hunnen. Legemet er (se PL X, Fig. 
27) sterkt fladtrykt, af temmelig regelnuessig oval Form, 
med den storste Brede kjendeligt starve end den halve 
Lsengde. Segmenterne er som hos Slmgten Janira skarpt 
begrmndsede og temmelig lost forbundne med hinanden, 
saint adskilte ved dybe laterale Indsnoringer. 
Iniegumenterne er faste, men gjennemsigtige og uden 
nogen tydelig udprmget Skulptur. 
Hovedet er forholdsvis stort og bredt, luesten af pen- 
tagonal Form og oventil i Midten noget hvselvet. Fortil 
gaar det ud i et noget fladtrykt, i Enden med 2 korte, ud- 
adboiede Spidser forsynet Pandehorn, og har til hver Side 
2 tilspidsede borstebosatte Fliger. 
Forkropssegmei^terne tiltager bagtil noget i Brede og 
er alle i Midten af den dorsale Flade forsynede med en 
opadrettet Torn. Epimererne er storkt udstaaende til Si- 
derne og noget forskjelligt formede paa de forskjellige Seg- 
menter. Paa lste Segment er de simpelt tilspidsede; paa 
de 3 folgende er de derimod tvedelte eller udgaaende i 2 
omtrent ligestore tilspidsede fligformige Fortsatser. Paa 
de 3 bagerste Segmenter endelig er Epimererne 3-fligede, 
med den midterste Flig laengst. Kanterne af disse Fliger 
er paa alle Segmenter tot haarbevoxede. 
Bagkroppen bestaar kun af et enkelt bredt, naesten 
halvcirkelformigt Segment, omtrent af Forkroppens halve 
Lmngde. Dots Overflade er ganske glat og noget hvselvet, 
hvorimod Kanterne er delte paa hver Side i 8 tilspidsede 
og haarbesatte Smaafliger eller grove Saugtakker, alle af 
ens Udseende. Solve Enden er sturnpt tilspidset og kun 
lidet fremspringende.

in form, with 8 strong, serrate teeth on either side. Second 
pair of antennae with the 2 basal joints jutting forth as a 
strong, outward-directed spine. Caudal appendages about 
half as long as abdominal segment, with trunk jutting 
out at extremity, on the inner side, as a. dentiform projec- 
tion; branches very small and unequal in length, the outer 
smallest. Colour whitish. Length 12”"”. 
Locality. — Stat. 164. 
Remarks. — The genus being at present exclusively 
represented by the species treated of here, it is, of course, 
difficult to determine with certainty what characters should 
be assigned specific weight. Meanwhile, as, in the genus 
Janira — which approximates this genus closest — the form of 
the head and the abdominal segment, as also the armature 
of the epimera, would appear to have greatest significance 
in this respect, T have seen fit to record those characters 
as specific peculiarities distinguishing the present form. 
Description of the Female. — The body (see PI. X. 
fig. 27) very much depressed, its form a comparatively reg- 
ular oval, with the greatest breadth perceptibly exceeding 
one-half of the length. The segments, as in the genus 
Janira, sharply defined, and rather loosely connected to- 
gether, being separated by deep lateral instrictions. 
The integuments, though compact, are translucent, 
and have no distinctly prominent sculpturing. 
The head is comparatively large and broad, almost 
pentagonal in form, and above, in the middle, somewhat 
arcuate. Anteriorly, it projects as a slightly depressed 
rostrum, furnished at the extremity with 2 short, outward- 
bent. points, and has on either side 2 acute, setiferous 
lobules. 
The free segments increase somewhat in breadth pos- 
teriorly, and in the middle of the dorsal surface are all 
furnished with an upward-pointing spine. The epimera 
project prominently toward the sides, deviating slightly in 
form on the different segments. On the 1st segment they 
are single acute, whereas on the 3 succeeding segments they 
are bipartite, or jut out as 2 acute lobular projections, 
about equal in size. Finally, on the 3 posterior segments 
the epimera are three-lobed, the medial lobe longest. The 
edges of these lobes are thickly clothed with hair on all 
the segments. 
The posterior division of the body consists of but one 
broad, almost semicircular segment, about half the length 
of the anterior division. Its surface is quite smooth and 
somewhat arched, whereas the edges are cleft on either 
side into 8 pointed and ciliated lappets, or coarse teeth, 
all similar in appearance. The extremity itself is obtusely 
pointed, and projects but very slightly. 
Xo trace whatever of eyes, as neither pigment nor 
any other visual element could be detected in the recent 
specimens.
