Bemaerkninger. At den ved Norges K yster forekom- 
mende Form er identisk med Montagu’s Art, derom lean 
der neppe vsere nogen Tvivl, og heller ikke den af Hoek 
ved Frankriges Nordkyst undersegte Form synes i nogen 
Henseende at skills sig fra vor Art. Da Hoek har taget 
sine Exemplarer paa den selvsamme Lokalitet, hvorfra 
Grube har sin P. Iwvis, og har paavist mindre Differentser 
hos ulige udviklede Individer, holder han Grube’s Art for 
identisk med sin, ligesom han anser det for sandsynligt, at 
den af Hesse som P. inermis opfprte Form heller ikke er 
artsforskjellig. Hvad endelig de to af Dohrn fra Golfen 
ved Neapel opferte Arter angaar, saa viser begge saavel 
stor Overensstemmelse indbyrdes som med den typiske Art. 
Den ene at Arterne, P. charybdceus opgives imidlertid at 
vrere mere end dobbelt saa stor som den anden, P. vulgaris , 
der derimod i saa Henseende ganske svarer til vor Art, 
med hvilken jeg derfor er tilboielig til at anse den for 
identisk. Philippi’s Endeis gracilis maa ligeledes aabenbart 
henregnes til denne Art. Som forskjellige Arter bliver 
saaledes kun tilbage P. charybdceus Dohrn, der forovrigt, 
naar afsees fra dens ualmindelige Storrelse. kun lidet synes 
at skille sig fra Montagu’s Art, og P. meridionalis Bqhm, 
som ifolge sit Findested (Singapoor) vel neppe kan vsere 
identisk mod nogen af de europseiske Arter. 
Beskrivelse. Legeinets Lsengde hos fuldt udviklede 
Hunner er omkring 4”' m , med en Spandvidde af 23”‘ w . 
Hannerne synes som Hegel at vaere noget, skjondt ikke 
meget, mindre end Hunnerne. 
Af Form er Legemet (se PI. I. Fig. 3, 3 a, 3 c, 3 d) 
than that succeeding it, frontal spines near together, the 
collar having above in the middle a slight sinus. Caudal 
segment oblong-oval, truncate at the extremity, and on 
either side armed with a short spine. Oculiferous tubercle 
exactly in the middle of the cephalic segment, prominent, 
acuminate, the 4 cornea? comparatively small, nearer the 
base than the point. Proboscis more than half as long as, 
and hardly slenderer than the rest of the body, slightly 
expanded in the middle. The false legs in the male about 
half the length of the body, 2nd joint largest, 5th joint 
larger than either of the 2 preceding or succeeding it, 
sharply curved, last joint triangular, scarcely half as long 
as the preceding, with 2 short spines on the inner margin. 
Ambulatory legs well-nigh thrice the length of the body, 
armed with .scattered spines, unequal in size, 2nd coxal 
joint longer than the 2 others taken together, femoral joint 
twice as long as coxal section, and terminating out- 
wards in a conical process, armed with 2 spines of dif- 
ferent length, 1st tibial joint shorter than 2nd, the 
latter about as long as femoral joint, tarsus obliquely 
rounded, propodus about 4 times longer than broad, term- 
inating outwards in a sharp corner, inner margin furnished 
at base with 5 strong spines, the 2 outermost placed side 
by side, terminal claw more than half as long as propo- 
dus, auxiliary claws about half the length of terminal claw. 
Body translucent, with the intestine and its lateral ex- 
pansions of a green colour. Length of body in the female 
4»m, ex t cn t 23’”’"; male somewhat smaller. 
Remarks. — That the form occurring on the coasts 
of Norway is identical with Montagu’s species, can hardly 
admit of doubt; nor indeed would the animal observed by 
Hoek on the north coast of France appear to differ in 
any respect from the present species. Hoek having taken 
his specimens in precisely the same locality whence Grube 
obtained his P. laevis, and having shown too minor differ- 
ences to characterise unequally developed individuals, he 
holds Grube’s species as identical with his own, regarding 
moreover as probable that P. inermis , established by Hesse, 
is not either specifically distinct. Finally, as to the two 
species established by Dohrn from the Bay of Naples, 
both exhibit close agreement alike individually and with the 
typical species. One of the species. P. charybdceus, is 
stated however to be more than double the size of the 
other, P. vulgaris, which in that respect agrees exactly 
with our species, with which therefore I am disposed to 
consider it identical. Philippi’s Endeis gracilis must like- 
wise obviously be referred to that species. Hence, as dis- 
tinct species we have left only P. charybdceus Dohrn, which, 
apart from its remarkable size would appear to differ but 
little from Montagus’s form, and P. meridionalis Bohm, 
that, judging from its habitat (Singapoor), can hardly be 
identical with any of the European species. 
Description. — The length of the body in fully de- 
veloped females reaches about 4 mm , with an extent of 23"™. 
The males would seem as a rule to be somewhat, though 
not much, smaller than the females.
