Bemserkninger. Denne Art er let kjendelig fra de 
piige bekjendte Arter af Skegten, foruden ved sin for- 
oddsvis betydelige Stprrelse, ved den eiendommelige Form 
sidste Fodpars Hofteled, ved de stumpt tilrundede Side- ,[ 
l'lader paa 3die Bagkropssegment samt ved det pukkelfor- 
lu ige Fremspring, som det folgende Segment danner oventil. 
Beskrivelse af Hunnen. Legemet er (se PI. XIII, 
' MS- 5) noget mindre underssetsigt end hos den ovenfor 
'oskrevne Phoxus-Art, men dog endnu temmelig plumpt, 
oied bred Byg og forholdsvis ikke meget hdie Epimerer. 
Hovedet er oventil temmelig stmrkt livadvet, med Pande- 
Pkiden ikke meget uddraget og ovenfra seet stumpt af- 
fundet.

(PI. XIII, fig3. 5, 5 a—m). 
Harpinia abyssi , (t. O. Sars, Crustacea X Pycnog. nova etc., No. in. 
Specific Character. — Body somewhat less thickset, 
with the back broad and not very large epimera. Head 
convex above, with comparatively short frontal plate. Lat- 
eral plates of 3rd abdominal segment equably rounded be- 
hind; 4th segment hunched above. Most ol the bristles 
ciliated. No eyes. First pair of antennae with basal joint 
exceedingly thick and massive, flagella short, almost uni- 
form in length. Second pair of antennae with penultimate 
joint of peduncle greatly dilated. The first 2 pairs of 
legs with hand inverted - pyriform , palmar margin very 
oblique, and posteriorly defined by an obtuse angle. Fifth 
pair of legs with basal joint linear. Last pair of legs 
with basal joint irregular in form, broader than long, pos- 
teriorly very arcuate; anteriorly, oblique truncate in the 
lower corner, and closely beset with long, ' ciliated bristles. 
Last pair of caudal stylets short, outer branch beset with 
bristles, inner somewhat shorter, awlshaped-acute, naked. 
Telson very small, broader than long, cleft to the middle. 
Colour greyish-white. Length reaching 13”™. 
Locality. — Stats. 18, 31, 33, 40, 51, 87, 124, 192, 
200, 240, 248, 251, 283, 295, 312. 
Remarks. — This form is easily distinguished from 
all other known species of the genus, not only by its com- 
paratively very considerable size but also by the peculiar 
form characterizing the basal joint of the last pair of legs, 
by the obtusely rounded lateral plates on the 3rd abdominal 
segment, and finally by the hunched projection formed above 
by the succeeding segment. 
Description of the Female. — Tile body (see PL 
XIII fig- 5) is somewhat less thickset than in the Phoxus 
species described above, but still rather clumsy in form, 
having the back broad and the epimera relatively not very deep. 
rpii e head is considerably arched above, with the 
frontal plate not very much produced, and presenting, when 
viewed from above, an obtusely rounded appearance. 
The 4 anterior pairs of epimera are somewhat, though 
not much, higher than the body itself, and furnished along 
the lower margin with a row of bristles, finely ciliated, as 
is generally the case, too, on the appendages (see fig. 5 h). 
The 4th pair are rather broad, and have the posterior border, 
below the emargination, uniformly arched. The 5th pair 
(see fig. 5 *) are irregular-transversal in form, with the 
anterior part slenderly wedge-shaped, the posterior consider- 
ably deeper and somewhat angular.
