jeg har flere Exempler, saavel Hannor sora Hunner. Arten 
er utvivlsomt at betragte som en mgte arktisk Form, skjondt 
egentlig kun 2 af de ovenmevnte Stationer tilhorer den 
kolde Area. 
viz. the Varanger Fjord, whence I have several specimens, 
both male and female. The species must unquestionably 
be regarded as a true Arctic form, though but 2 of the 
Stations strictly belonged to the cold area.

Artscharaeteristik. Forkroppen stserkt opsvulmet, med 
bred Ryg, Bagkroppen sammentrykt og oventil svagt kjolet, 
men utlen dorsale Fortsatser. Hovedet meget lidet, med 
et kort Pandehorn og afmndede Sidehjqrner. Epimererne 
smaa og jevnt tilrundede. De 3 forreste Bagkropssegmenters 
Sideplader store, med de nedre bagre Hjorner tilspidsede 
og den bagre Rand glat. 0inene smaa, ovale, hvide, be- 
liggende langt nede paa Hovedets Sider. lste Par Folere 
ualmindelig robuste, med Skaftets 2 forste Led store og 
noget opsvulmede, 3die meget lidet; Svoben noget lfengere 
end Skaftet, cylindrisk, bagtil forsynet med st ter let udvik- 
lede Calceoler. 2det Par Folere noget korterc og tyndere 
end lste Par, ligeledes med Calceoler i den forreste Rand 
af Svoben og Skaftets sidste Led. De 2 forreste Fodpar 
med store ovale Gribehaender ; de 2 folgende Par smrdeles 
spinkle; de 3 bagerste sttnrkt- forlrengede, omtrent ens ud- 
viklede, med Hofteleddet ovalt, Endekloen smrdeles lang.

Bemserkninger. Den her omhadlede Form afviger i 
enkelte Henseender temmelig meget fra de ovrige til Sltegten 
Tritropis henforte Arter og lean maaske vise sig at danne 
Typon for en egen Slaegt. Da imidlertid kun et enkelt 
Exemplar foreligger, og jeg paa (letter ikke har kunnet noiere 
undersoge Munddelene og Halevedhamget, tror jeg indtil 
videre at burde hen fore den til ovenmevnte Sltegt, hvortil 
den ialfald ntermest syncs at slutte sig. Arts beme v n else n 
er hentet fra de ussedvanlig stterkt udviklede Calceoler, 
hvormed begge Par Folere er forsynede.

Specific Character. — Anterior division of body greatly 
swollen, with back broad, posterior division compressed, and, 
above, faintly keeled, but without dorsal projections. Head 
very small, with rostrum short and rounded lateral cor- 
ners. Epimera small, and evenly rounded off. Lateral 
plates on the 3 anterior abdominal segments comparatively 
large, with lower, posterior corners acute and posterior 
margin smooth. Eyes small, oval, white, placed far down 
sides of head. First pair of antennae unusually robust, 
with the 2 first joints of peduncle large and somewhat 
swollen, 3rd exceedingly small; flagellum a trifle longer 
than peduncle, cylindric. posteriorly furnished with promi- 
nently developed calceolse. Second pair of antenme some- 
what shorter and more slender than 1st pair, having like- 
wise calceolse along anterior margin of flagellum and on 
last joint of peduncle. The 2 anterior pairs of legs with 
oval hands; the 2 succeeding pairs remarkably slender; 
the posterior 3 greatly produced, about uniform in develop- 
ment, with basal joint oval, terminal claw exceedingly long- 
Caudal stylets diminishing backwards successively in length, 
with branches of equal size. Telson — ? Colour whitish, 
translucent. Length 1 3 1 //™.

Remarks. — The form treated of here exhibits in 
some respects a rather striking deviation from the other 
species referred to the genus Tritropis, and may possibly 
bo found to constitute a separate genus. Meanwhile, as 
one specimen only was secured, and therefore not having 
had opportunity of submitting the oral parts and caudal 
appendages to a thorough examination, I have seen fit, for 
the present, to refer the animal in question to the aforesaid 
genus, which at least it would appear to approximate clos- 
est. The specific designation is derived from the remark- 
ably developed calceolas, occurring on both pairs of an- 
tenna).
