Beskrivelse af Hunnen. Legemet er (se PI. XVIII, 
Fig. 3) af den saidvanlige smale og liriesere Form og viser 
paa Rygsiden en Del meget smaa, men temmelig regelmses- 
sigt ordnede Knuder, der navnlig paa dot bagre Parti er 
tydeligt frem tnedende. 
Hovedet er meget lidet, afrundet, uden Pandehorn og 
viser oventil 2 meget smaa, jevnsides stillede Knuder. Dot 
forbinder sig med Kroppen ved en meget skjsev, skraat for- 
tilrettet Sutur. 
Af Rropssegmenterne er det lste forholdsvis kort og 
viser oventil ligeledes 2 smaa Knuder, der liar sin Plads

(PL XVIII, %. 3, 3 x-a). 
Caprella microtuberculata, (1. 0. Sars, Crust. & Pycnogonida nova etc., 
No. 43. 
Specific Character. — Body slender and elongate. 
The 4 anterior segments in female furnished with small 
scattered protuberances, in male almost quite smooth. Fifth 
segment having above in both sexes 6 protuberances, ar- 
ranged in pairs, 2 anterior and 4 posterior; 6th and 7th 
each with 4 larger ones, arranged in a transverse series. 
The 2 anterior segments in male more elongate than in 
female; 1st segment in both sexes shorter than 2nd. 
Eyes small, round, with red pigment. First pair of an- 
tennae greatly produced, with flagellum consisting of numer- 
ous short articulations; 2nd pair scarcely one- third as 
long, and posteriorly having a dense armature of bristles. 
Second pair of legs of well-nigh uniform appearance in 
both sexes, with large oval hand, furnislipd below with 2 
small teeth, separated comparatively by a wide interspace, 
and exhibiting anteriorly a sharply produced corner. The 
3 posterior pairs of legs powerfully developed, with last 
joint, or hand, expanded at base, and longer than the 2 
preceding ones taken together. Body translucent, mar- 
bled over with comparatively large brownish-red patches of 
pigment. Length 12 — 17 m ™. 
Locality. — Stats. 315, 336. 
Remarks. — Of the previously known species, this 
approximates closest C. linearis Lin., but admits at once of 
being distinguished by the much more produced 1st pair of 
antenna?, the form of the 2nd pair of legs, and the different 
colouring. 
Description of the Female. — The body (see Ph 
XVIII, fig. 3) has the usual slender and well-nigh linear 
form, exhibiting on the dorsal side a number of very small 
and comparatively in regular arrangement disposed protuber- 
ances, — distinctly prominent, more especially over the 
posterior part. 
The head is very small, rounded, without any rostrum, 
and exhibits above 2 very diminutive protuberances, placed 
side by side. It is connected with the body by an ex- 
ceedingly oblique, forward-directed suture. 
Of the body-segments, the 1st is comparatively short, 
likewise with 2 small protuberances, placed above on the 
posterior part. The 2nd segment is almost twice as long, 
and somewhat fusiform in appearance, as also very movablv
