Bemaerkninger. Den her omhandlede Art kan ikke 
forvexles med foregaaende. Mere ligner den vore 3 inden- 
landske Alter: A. maxillaris, elongatus og dentatus, fra 
hvilke den dog let kjendes ved sine t;et borstebesatte Iu- 
tegumenter. 
Beskrivelse af Hannen. Legemet er (se PI. VIII, 
Fig. 23) kjendeligt kortere og plumpere end bos foregaa- 
ende Art, neppe 3 Gange saa langt som bredt og fortil 
ikke maerkbart afsmalnende. 
Integumenterne er vistnok temmelig faste, dog langtfra 
i den Grad som bos foregaaende Art, og er del vis ru af 
meget smaa Pigge samt besat med lange og trntte Haar, 
navnlig paa den forreste Del af Kroppen. 
Hovedet er meget bredt, naesten lirkantet, med Pande- 
randen i Midten kuu lidet fremspringende og Sidedelene 
jevnt convexe, uden nogen tydelig Kjol. Supraorbitalfort- 
satserne er tydelige, skjondt temmelig smaa. 
Af de frie Forkropssegmenter er de 2 forreste som 
bos foregaaende Art kortest. 3die Segment er ved en dyb 
Iudsnoring skilt fra det folgende og er ligesom de 2 fore- 
gaaende Segmenter og Hovedet ru af talrige Smaapigge,

Specific Character. — Body thickset scarcely 
3 times as long as broad, and not perceptibly tapering- 
forwards. Integuments on anterior portion of body 
rough, by reason of minute spikes, and thickly covered 
with hairs. Head large and broad, well-nigh quadrate, 
with the lateral parts uniformly convex, and without any 
keel. The 2 posterior pedigerous segments without spikes, 
but with rounded epimera; penultimate segment largest, 
and exhibiting above a cruciform depression. Abdomen, 
above, smooth, with sharply pointed, bristle-beset epimera. 
Eyes distinct, but small, with a dark-coloured pigment. An- 
tennae ol the usual structure. Mandibles moderate in size, 
with a small but distinct tooth on the outer margin, ex- 
tremity acutely pointed. Pleopoda with narrow, bristleless 
terminal plates. Median caudal plate oblongo-triangular, 
with the extremity pointed, and furnished with 2 slender, 
diverging bristles. Colour a uniform dirty greyish-brown. 
Length 5 1 / 2 mM .

Bomarks. — The species here treated of cannot be 
confounded with the preceding. It has closer resemblance to 
our 3 native (Norwegian) forms viz. — A. maxillaris, A. elong- 
atus, and A. dentatus, from which however it may easily be 
recognized by the densely bristle-beset integuments. 
Description of the Male. The body (see PL VIII, 
fig. 23) is perceptibly shorter, as also more clumsy in form, 
than in the preceding species, scarcely 3 times as long as 
broad, and not obviously tapering anteriorly. 
The integuments are indeed rather firm, though by 
no means to the same extent as in the preceding species, 
and in places rough, by reason of minute spikes, as also 
clothed with long and close hairs, in particular on the an- 
terior part of the body. 
The head is very broad, almost quadrate, with the 
frontal margin projecting but slightly in the middle, and 
the lateral parts uniformly convex, without any distinct 
keel. The supraorbital projections are distinctly defined, 
though comparatively small. 
Of the free segments belonging to the anterior divi- 
sion the 2 foremost are, as in the preceding species, short- 
est. The 3rd segment is separated by a deep instriction 
from the succeeding one, and, like the 2 preceding segments
