med vel udviklede Synselementer. Sunbolen kort, fortil- 
rettet, uoget udvidet i sit ydre Parti; Mundaabningcn sim- 
pel. Saxlemmeme forboldsvis korte, Skaftet tykt, cylindriskt, 
Haanden aflang oval, med Fiagrene koniskt tilspidsede og 
fint tandede i Inderkanten. De lalske Fodder strerkt- for- 
lsengede og smale, 10-leddede, 5te Led hos Hannen kengcre 
end de 0vrige og ved Enderi forsynet med en kort tilbage- 
boiet Flig ; de 4 ydre Led langs Inderkanten besatte med 
en regelmrcssig Rad af ])ladeformige, i Kantorne fint cilie- 
rede Tomer; sidste Led stumpt tilrundet i Enden, uden 
Klo. Gangfodderne mere eller mindre staerkt forlamgede, 
sparsomt borstebesatte, med Laarleddet staerkt opsvulmet 
lios Hunnerne; Tarsalleddet yderst lidet; Fodleddet kraf- 
tigt udviklet og bevsebnet i Inderkanten ved Basis med 
stserke Torner; Endekloen forboldsvis kort, men kraftig; 
Bikloerne vel udviklede. Kjonsaabningerne bar Hunnen ved 
Enden af 2det Hofteled paa alle Fodder, hos Hannen kun 
paa de 2 bagerste Par. De ydre rEg meget store og fse- 
stede enkeltvis til de lalske Fodder, uden at were sammen- 
kittede til sammenhcxmgende Masser. 
Bomserkninger. I den Begrsendsning, bvori Skegteu 
her tages, er den hovedsageligt cbaracteriseret ved den f'or- 
holdsvis snuekre, cylindriske Krop, den eiendommelige TJd- 
vikling af Hovedsegmentet, den ualmindelig korte Snabel, 
Saxlemmernes og navnlig de lalske Fodders Structur, ende- 
lig ved Tilstedev.nerelsen af vel udviklede Bikloer paa Gang- 
fodderne. Ligeledes tor de 2 sidste Kropssegmenters Sam- 
mensmeltning gjselde for et generiskt Mserke. 
Typen for Slmgten er den nedenfor noiere beskrevne P. 
brevirostris, Johnston. I den nyere Tid er desuden afDohrn 
opfort 4 middelhavske Arter, der utvivlsomt horer ind un- 
der denne Slaegt og slutter sig meget n;er til den typiske 
Art, bvortil endnu kommer en 6te nordisk Art, som i det 
folgende nffirmere skal beskrives. 
protuberant, with well developed visual elements Proboscis 
short, anteriorly directed, somewhat expanded in its outer 
part; oral orifice plain. Chelifori comparatively short, 
scape thick, cylindric, hand oblongo-oval, with the fingers 
conically pointed and finely dentated along the inner mar- 
gin. False legs very elongate and slender, ten-jointed, 5th 
joint in male longer than the rest, and furnished at the 
extremity with a short recurved lappet : the 4 outer joints 
along the inner edge armed with a regular series of lamel- 
lar spines, finely ciliate along the margins ; terminal joint 
obtusely rounded at the extremity, without any claw. 
Ambulatory legs more or less prolonged, sparingly setous, 
with the femoral joint a good deal swollen in the female; 
tarsal joint exceedingly small ; propodal joint powerfully 
developed, and armed along the inner edge, at the base, 
with strong spines; terminal claw comparatively short, but 
powerful; auxiliary claws well developed. Sexual openings 
in female at the end of the 2nd coxal joint on all the 
legs, in male on the 2 posterior pairs only. The outer 
eggs very large, each fixed by itself to the false legs, 
without being glued together in masses. 
Bemarks. In the restricted sense in which the genus 
is taken here, its chief characteristics consist in the com- 
paratively slender cylindrical body, the peculiar development 
of the cephalic segment, the remarkably short proboscis, 
the structure of the chelifori, and more particularly that of 
the false legs, and finally, in the presence of well developed 
auxiliary claws on the ambulatory legs. The coalescence 
of the 2 last segments of the trunk may likewise perhaps 
be taken as a generic feature. 
The type of the genus is P. brevirostris, Johnston, 
described in detail below. Of late, too. Dohrn has estab- 
lished 4 Mediterranean species, unquestionably referrable 
to this genus, which agree very closely with the typical 
species, to which comes a Northern species — the 6th, 
described more at large in the sequel.
