af Fremspring ; men disse er her ( se Fig. 2 a) betydelig 
lavere, stumpt afrundede i Spidsen og det forreste og ba- 
gerste af dem neppe mere end antydede. Ligeledes findes 
ved Enden af enhver af Sidefortsatserne oventil en ganske 
lav. knudefonnig Forhoining. Af Segmeriterne er det for- 
reste, eller Hovedsegmentet som saedvanlig stprst og nsesten 
af samme Lsengde som Brede, med Pandedelen meget kort 
og som hos foregaaende Art endende med en cirkulser I or- 
tykkelse, hvori Snabelen er ligesom indsmnket (se Fig. 2 c). 
Halesegmentet (se Fig. 2 og 2 h) er forholdsvis omtrent af 
samme Lsengde soin hos P. littorale, men at en temmelig 
afvigende Form. Det er nemlig aflangt ovalt, eller mcsten 
cylindriskt, med det ydre Parti ganske jevnt afrnndet, ikke 
som hos foregaaende Art spadeformigt udvidet og alkuttet 
i Spidsen. 
0ieknuden (Fig. 2 b) er stumpt afrundet og rettet 
noget forover saint beliggende ganske n;ur Hovedsegmentets 
Forkant (se Fig. 2 a). De 4 Oorneae er kjendelig storre 
end hos foregaaende Art og ogsaa mermere stillede sam- 
men (sml. Fig. 2 b og 1 b). 
Snabelen (se Fig. 2, 2 a, 2 c) er af et meget charac- 
teristiskt Udseende og temmelig ulig samme hos P. littorale. 
Deft er forholdsvis kort og tyk, neppe mere end '/» saa 
lang soin det ovrige Legeme og noget slcraat nedadrettet. 
AfForm er den nsesten cylindrisk, kun meget lidet afsnial- 
nende mod Enden, der ikke som hos foregaaende Art er 
smalt udtrukket, men stumpt alkuttet. Mundaabningen 
viser heller ikke en saa regulier trekantet Form som hos 
hin Art, men bar Kanterne noget uregelnnessigt foldede 
(se Fig. 2 c). 
De falske Fodder hos Hannon (se Fig. 2 c, 2 d) er 
yderst smaa og forholdsvis kjendelig spinklere end hos P. 
littorale, nsesten traadformige. Lsengdeforholdet af de en- 
kelte Led er ogsaa temmelig afvigende. Saaledes er her 
de 2 forste Led ubetinget de storste, og af de folgende 
Led er det 5te og 6te noget storre end baade de 2 fore- 
gaaende og efterfolgende. Endekloen (se ogsaa F ig. 2 e) 
er kjendelig tyndere og viser kun en ganske svag og jevn 
Krumning. De paa disse Lemmer feestede Horner er meget 
smaa og spredte uden nogen bestemt Orden, dels i Kan- 
terue, dels paa den ydre eller indre Side al Leddene. 
Gangfodderne (Fig. 2 f) er adskilligt kortere end Le- 
gemet og viser idethele en med samme bos foregaaende 
Art temmelig overensstemmende Bygning, dog med enkelte 
mindre Afvigelser. Af Leddene er det 4de ellei Laailed- 
det baade det storste og kraftigste, omtrent af samme 
Lsengde som de 3 Hotteled tilsammen, og kjendelig ten- 
ge re end det folgende Led. Det viser indad et lignende 
vinkelformigt Fremspring som hos P. littorale, hvorimod 
de hos denne Art ved Enden af dette og de 2 folgende 
Led forekommende koniske Fortsatser mangier eller er i 
ethvert Fald yderst utydelige. De 2 Lrngled aftager hur- 
tigt baade i Lsengde og Tykkelse og har hvert mer Enden 
cur as in the preceding species a series of projections; but 
in this animal they are considerably lower, obtusely rounded 
at the point, and the first and last but little more than 
rudimentary. Moreover, at the extremity of each lateral 
process we observe above a low, knob-shaped protuberance. 
Of the segments, the foremost, or cephalic segment, is as 
usual the largest, and well-nigh of' the same length as 
breadth, with the frontal part exceedingly short and, as in 
the preceding species, terminating in a circular inspissation, 
into which the proboscis would seem, as it were, to be 
sunk (see fig. 2 c). The caudal segment (see fig. 2 and 2 h) 
is relatively of about the same length as in P. littorale, 
but rather different in form. It is oblongo-ovate, or 
almost cylindrical, with the outer part uniformly rounded 
off, not as in the preceding form spatulate-expanded and 
truncate at the point. 
The oculiferous tubercle (fig. 2 b) is obtusely rounded 
and directed somewhat forwards, as also placed close to 
the front margin of the cephalic segment (see fig. 2 a). 
The 4 cornea; are perceptibly larger than in the preced- 
ing species and nearer together (compare fig. 2 b with 
fig. 1 b). 
The proboscis (see fig. 2, 2 a, 2 c) has a most charac- 
teristic appearance, differing riot a little from that in P. 
littorale. It is relatively short and thick, hardly more than 
one-third as long as the rest of the body, and points some- 
what obliquely downward. In form it is almost cylindrical, 
tapering but very slightly towards the extremity, which is 
not, as in the preceding species, slenderly produced, but 
obtusely truncated. Neither does the buccal orifice show 
so regularly triangular a form as in that species, but has 
the margins irregularly folded (see fig. 2 c). 
The false legs in the male (see fig. 2 c, 2 d) are 
very small indeed and more appreciably slender than 
in P. littorale, nay almost filiform. The relative length 
of the different joints differs too considerably. Thus, 
in this animal the 2 first joints are without question the 
largest, and of the following the 5th and 6th are a trifle 
larger than both the 2 preceding and the 2 succeeding 
ones. The terminal claw (see also fig. 2 c) is perceptibly 
thinner, and exhibits but a very slight and uniform bend. 
The spines observed on these limbs are very small, and 
occur scattered, without regular arrangement, partly along 
the margins and partly on the outer or inner surface of 
the joints. 
The ambulatory legs (fig. 2 f) are a good deal shorter 
than the body, and exhibit on the whole a structure agree- 
ing rather closely with that in the preceding species, though 
with a few minor differences. Of the joints, the 4th or 
femoral joint is the largest and most powerful, about 
equal in length to the 3 coxal joints taken together, and 
appreciably longer than the succeeding joint. It has an 
angular projection similar to that in P. littorale, whereas 
the 2 conical processes observed in that species at the ex- 
tremity of this joint and of the 2 following ones are want- 
ing, or at least very indistinct. The 2 tibial joints diminish 
rapidly alike in length and thickness, and have each, near
