K.UNGL. SV. VET. AKADEMIENS HANDLINGAR. BAND 59- N:0 4. 2 1 



P t 39 — 48, 20 — 22 mm. The basal joints about as long as they are broad, 

 the length of the distal ones 1 V- times the breadth. The proximal segments with 

 lateral, black spöts. P 2 36 — 43, 20—23 mm, basal joints as by Pj, a little flattened. 

 P ;! -38 (20 mm); P 4 26, 13 mm; P, 24, 10 mm; P ]M 15, 8 mm. The distal pinnules 

 about 20, 8 mm. 



The segments of the division series smooth, the Br. joints more and more 

 collar-shaped, the arms laterally a little compressed. An oval interspace between 

 the innermost II and III Br:s. 



Arms large, bent towards the mouth, which is central. All the arms with am- 

 bulacral furrows. The skin on the anal tubus encrusted with coarse lime granules. 

 The intestines half knocked off from the dorsal part of the animal. 



Colour on the living animal (according to a statement enclosed) beneath 

 (= dorsally) yellow-white, ditto above (= ventrally). The pinnules dark with whitish, 

 rectangular small spöts. The specimen in spirit yellow-brown, the arms being 

 chocolate brown ventrally. The segments of the distal pinnules have dark bands 

 with white ends of the segments, by which the pinnules get a distribution of colours 

 that looks like a string of pearls. 



Description of the specimen from Station 11: Zygometra microdiscus var. elegans. 



Cd hemispherical. Dorsal face coloured by shallow, black-margined pits (due 

 to the C:i having fallen off), 3 mm. 



C XXX (of which X fresh joint-cavities and V young C). In the interiör (dor- 

 sal) row 25—28 mm: 33(10), 35(10), 35(10). I-E 36(12), 42(13). Exteriör (ven- 

 tral) row 32—35 mm: 42 (13), 42 (13), 45 (14). The remaining C broken. The segments 

 most often shorter than they are broad, the next to the first spiny segment longest, 

 as long as or longer than its breadth. Dorsal spines Vz^/s of the breadth of 

 the segments. Opposing spine a little longer than the preceding, about as high as 

 the breadth of the segment, starting from the whole dorsal surface. Terminal claw 

 rather curved, 2 — 3 times as long as the penultimate segment. The spines of the C 

 and their fixing points white-coloured. Basal segments distally white-coloured. 



Arms > 37 (probably about 40), 105 mm. 



R:s projecting as narrow ribbons, laterally contiguous. I Br:s 1 separated from 

 one another; breadth 4 times the length. I Br 2 united with the preceding ossicle by 

 a syzygy, narrowly pentagonal, in the median line a little broader than I Br 1. 



II Br:s are 4 (1 — 23 + 4) appearing in 9 cases. I Br:s 1 soldered together basally 

 two by two inside, the same is the case of the following primipostaxillaries. III Br:s 

 either 2 (in 14 cases) or 4 (in one case). IV Br:s 4 (1—2 3 + 4) appcar in all 4 cases.
