Bemserkninger. Denne Form staar vistnok .meget 
nser Kroyers Anonyx Vahln, hvortil Goes henforer den, 
men er dog Utvivlsomt artsforskjellig. Foruden ved sin 
langt betydeligere Storrelsc og mere underssetsige Krops- 
forni, kjendes den meget let i alle Aldre ved don eiendom- 
melige Form af 3die Bagkropssegments Sideplader, derikke 
som hos hin Art danner bagtil en jevnt tilrundet CJdbugt- 
ning, men gaar ud i 2 spidse Takker, hvorfra ogsaa den 
af Sp. Bate foreslaaede Artsbenaevnelse er hentet. 
Beskrivelse af Hunnen. Legemet er (se PI. XII, 
Fig. 1) i Sammenligning med den anden Art af temmelig 
plump Form, med jevnt hvselvet Rygflade og ualmindelig 
lmic Epimerer. 
Hovedet er forholdsvis lidet, betydelig kortere end 
IsteForkropssegment og har Sidevinklerne tilspidsede, skjondt 
ikke meget fremspringende. En stor Del af dets Sider til- 
ligemed samtlige Munddelo dsekkes fuldstamdigt af lste Par 
Epimerer. 
Af Forkropssegmenterne er det lste noget lsengere 
end do nsermest folgende ; de 2 sidsto or atter noget kortere 
end det foregaaende. De 4 forreste Par Epimerer er over 
dolibelt saa hoie som selve Kroppen og synes forholdsvis 
smale, idet de gjonsidigt for en stor Del daekker hinanden. 
Det sidste af dem er som siedvanlig bagtil stserkt udrandet, 
for at kunne optage det fqlgende Par, og er nedenfor Ud- 
randningen uddraget i et skarpt Hjqrne. 5te Par Epimerer 
er af uregelmsessig firkantet Form og noget hoi ere end 
bredt; de 2 folgeride betydelig mindre. 
De 3 forreste Bagkropssegmenter har Sidepladerne 
brede og dvbe. Paa 3die Segment danner de bagtil 2 
skarpc Hjorner. hvoraf det nedre forestiller det egentlige 
Sidehjqrne, medens det ovro betydelig stmrkere fremsprin- 
gende danner en saeregen triangulser Fortsats. Imellem 
begge er der en jevn Udrandning. De folgende Bagkrops- 
segmenter er oventil jevnt livaelvede, uden Fortsatser eller 
Knuder. 
however but slightly. Lateral plates of 3rd abdominal 
segment jutting out posteriorly in the form of 2 trian- 
gular projections, separated bv a distinct emargination. the 
upper one the larger. Eyes narrow, reniform, or well- 
nigh linear, dark -brown in colour. First pair of an- 
tennae with short and thick peduncle; secondary flag- 
ellum elongate, consisting of 9 articulations. The 3 pos- 
terior pairs of legs short and robust, with basal joint 
broad, almost circular. Last pair of caudal stylets com- 
paratively short, projecting but very little, if at all, over 
the preceding pair. Telson cleft to the middle. Length 
reaching 36”"". 
Locality. — Stat. 366. 
Remarks. — This form does indeed approximate very 
closely Kroyer’s Anonyx Vahlii, to which Goes lias referred 
it, but is nevertheless without a doubt specifically distinct. 
Let alone its far greater size, and more thickset body, the 
species may be easily recognized, in all stages of develop- 
ment, by the peculiar form distinguishing the lateral plates 
of the 3rd abdominal segment, which do not, as in the 
forementioned species, exhibit behind an evenly rounded curve, 
but jut forth as 2 acute teeth, a character indeed from which 
the specific appellation suggested by Sp. Bate is taken. 
Description of the Female. — The body (see PI. 
XII, fig. 1), as compared with that in the other species, 
rather clumsy in form, with a equably arched dorsal sur- 
face and remarkably deep epimera. 
The head comparatively small, much shorter than the 
1st thoracic segment, and with the lateral angles pointed, 
though not to any great extent projecting. A very con- 
siderable portion of the sides, as also the oral appendages, 
are entirely covered by the 1 st pair of epimera. 
Of the thoracic segments, the 1st is somewhat longer 
than those immediately succeeding it; the last 2 being 
also a trifle shorter than the preceding. The 4 anterior 
pairs of epimera are upwards of double the height at- 
tained by the body itself, and apparently slender, covering 
one another, as they do, to a great extent. The last of 
these pairs are as usual very considerably emarginate pos- 
teriorly, to serve for the reception of the succeeding pair, 
appearing produced below, as an acute angle. The 5th 
pair of epimera have an irregular, quadrate form, their 
height slightly exceeding their breadth; the 2 succeeding 
pairs are considerably smaller. 
The 3 anterior abdominal segments have the lateral 
plates broad and deep. On the 3rd segment, they con- 
stitute posteriorly 2 sharp corners, of which the lower rep- 
resents the true lateral corner, whereas the upper, jutting 
forth much more prominently, constitutes a characteristic 
triangular projection. Between the two occurs a uniform 
emargination. The succeeding abdominal segments are equa- 
bly arched above, without either projection or protuber- 
ance.
