Bemserkninger. .Teg anser det for noget tvivlsomt, 
hvorvidt alle i ovenstaaende Synonymliste opregnede For- 
mer i Yirkelighcden refererer sig til denne Art. Den af 
Goodsir som P. globosum opfprte Form kan vistnok erkjen- 
des som en Phoxiehilidium; men den er altfor ufuldkom- 
ment beskrevet og afbildet til at Arten med Sikkerhed kan 
bestemmes. Ligeledes er jeg i nogen Tvivl, hvorvidt den 
af Hoek veil Holland og Nordkysten af Frankrige iobser- 
verede Form er samme Art. Fodleddets Bevsebning er 
nemlig, efter de af Hoek leverede og som det synes meget 
noiagtige Afbildiiinger. temmelig forskjellig ved det ringe 
Antal af Torner, der er fsestede til Inderkantens basale 
Udvidning, Hos alle de af mig undersOgte Exemplarer er 
Tallet af disse Torner constant 6, og henned stenimer 
ogsaa livad Wilson angiver for den nordamerikanske Form, 
hv'is Identitet med den typiske Art synes at vsere utvivl- 
som. 
Beskrivelse. Hunnens saidvanlige Lsengde er omkring 
3”™, med en Spandvidde af 20”™; Hannerne er som smd- 
vanlig noget rnindre. Exemplarer fra Gronland er dog 
adskilligt stprre. 
Legemet er (se PI. II, Fig. 1, la, lb) forholdsvis 
temmelig under smtsigt, cylindriskt, noget tykkere fortil end 
bagtil. og bar Segmenterrie ved vel markerede Suturer be- 
gramdsede fra hinanden. Sidefortsatserne er forholdsvis 
korte, neppe lamgere end Legemet er bredt, og skilte ved 
temmelig brede Mellemrum; naar undtages paa sidste 
Kropssegment, udgaar de omtrent fra Midten af Segmen- 
terne. Hovedsegmentet er noget leengere end det folgende 
Kropssegment og liar Pandedelen forholdsvis meget kort, 
neppe fremragende over Snahelens Basis og i Forkanten 
mellem Roden at Saxlemmerne svagt indbugtet. Haleseg- 
mentet er forholdsvis lidet, af simpel oval Form og neppe 
tydeligt afgraendset fra sidste Kropssegment; det er altid 
the frontal part very short and slightly incurved at the 
middle of the fore margin. Caudal segment comparatively 
small, oval, unarmed. Oculiferous tubercle obtusely conic, 
the 4 cornea 1 rather small, placed nearer the base than the 
extremity of the tubercle. Proboscis scarcely half as long 
as rest of body, cylindrical, truncate at extremity. Cheli- 
fori longer than proboscis, chela a little shorter than 
scape, fingers the length of palm, exceedingly powerful 
and hooked at the points. The false legs in the male 
attaining when fully extended almost the length of the 
body, exclusive of proboscis, sharply bent in an sigmoid 
curve, 3rd joint longest, last joint a little shorter than 
penultimate, with 3 strong, unguiform spines on the inner 
margin, near the base, and a row of more slender spines 
along either side. Ambulatory legs rather powerful, about 
2 x / 2 times as long as the body, almost bare; femoral joint 
largest, the '2 tibial joints about equal in length, tarsus 
irregularly triangular, propodus about 3 times longer than 
broad, inner margin at base armed with G strong spines, 
terminal claw a little more than half as long as propodus, 
auxiliary claws plainly projecting, but small. Colour red 
or brownish (sepia-tint). Length of body in female 3’"’"; 
extent 20”™. 
B,emarks. — I regard as somewhat doubtful whether 
all the forms enumerated in the above List of Synonymes 
can properly be referred to this species. The form estab- 
lished by Goodsir as P. globosum, may certainly pass for 
a Phoxichilidium ; it is however much too imperfectly de- 
scribed and figured to admit of determining the species with 
certainty. Likewise, I am far from sure that the form 
observed by Hoek off the coast of Holland and the north coast 
oi France is the same species. The armature of the pro- 
podus must, judging from Hoek’s various and, it would 
seem, very accurate representations, differ not a little by 
reason of the small number of spines affixed to the basal 
expansion of the inner margin. In every specimen I have 
examined, the number of these spines was constant, viz., 
6 ; and this agrees too with what Wilson states for the 
North American form, whose identity with the typical spe- 
cies would appear to be unquestionable. 
Description. — Usual length of female about 3™”, 
with an extent of 20"™; the males as a rule somewhat 
smaller. Specimens from Greenland however attain a con- 
siderably larger size. 
The body (see PI. II, fig. 1, 1 a, 1 b) is compara- 
tively rather squareset, cylindric, somewhat thicker anteriorly 
than posteriorly, and has the segments limited by well- 
defined sutures. The lateral processes are comparatively 
short, hardly longer than the body is broad, and separated 
oue from the other by rather wide intervals; save on the 
last segment of the trunk, they issue from about the middle 
of the segments. The cephalic segment is a trifle longer 
than the succeeding segment of the trunk, and lias the 
frontal part comparatively very short, projecting hardly 
beyond the base of the proboscis, and on the anterior 
margin between the origin of the chelifori slightly incurved. 
The caudal segment is comparatively small, of a simple
