inside. II Br — s: 2. Arms XVI, 90 mm. slendei-, smooth, well sepa- 

 rated basally. Inconspicuous synarthrial tubercles. The br of Br 1: 

 1.1 — 1.2 mm. p]xample of syzygies: 3 + 4, 11 + 12, 17 + 18 etc., dis- 

 tally with an interval of 3 — 4( — 5) oblique articulations. Br 1 — 7 dis- 

 ooidal, then oblique Joints. The longer side of the distal Br — s: L=br. 

 19 — 20 segment per cm. (15, if the syzygial pairs are counted as units). 



Pj 15: 5,5 mm. smooth. P., 19: 9—9,5 mm. (5"' — 12*'' segment: 

 L = 2 — 2 ' 2 br, with spiny pi'ominences on the distal ends of the seg- 

 ments. The tip of the pinnule usually smooth), Pg 14-^15; 7 — 7,5 mm. 

 similar to the preceding. P^ (12; 4 mm.| and the following ones smooth. 

 Distal p. 20 — 22; 8 mm. (P' and 2'' segment short, coarser than the 

 following ones, the distal end of the 2^" segment therefore forms a 

 weak notch against the outer segments which are longer, L = 2 — 3 

 X l)r: the last segment provided with microscopic dorsal hooks). Disk 

 tiirown off. 



Cirri and division-series white. The distal parts of the arms 

 spotted with red-brown. Pi'oximal pinnules white, the other p — s with 

 strongly coloured sacculi (which are about 4 pairs per segment) and 

 otlierwise light brown-violet. 



The scheme given below is an example of the piiinulation of 

 the proximal arm parts. Pj is always lacking on the inner side, when 

 there are 4 arms on a I Brax.
