tinctly limited tubercle, not at all or only slightly prominent in lateral 

 view. Br 1 and 2 with a similar though still smaller prominence. 

 Br — s inwardly united basally: Ex. of syzygies: 3 + 4, 9 + 10, 14 + 15 

 etc. with an interval of 8 (exceptionally only 2) oblique articulations. 

 Arms X, 40 — 45 mm. First 10 Br— s discoidal, not »wall-sided», then 

 oblique joints. Arms smooth. 



Pj 13 — 15; 3 — 5 mm. (The pinnulars smooth, cubical to L = 

 1 1 2 X br). P., 16; 5 — 0,5 mm., longer and stouter than the preceding 

 pinnule, the middle segments often with small, distal tubercles, Pj 12; 

 3 — 4 mm. as the following ones smooth; P^ 13; of the same length or 

 shorter. P5 and the following pinnules again longer. P^^ absent, P,, 14; 

 4,5 mm. Distal p-s + 20; 5 mm. (P' and 2'' segments shbrt, 3'' cubi-

 Colour light-brown (in the preserved animal). 



Sp. 2 (St. 13) Cd knob-formed, free dorsal surface 1,3 mm. Ter- 

 minal claw about as long as the penultimate segment. — Axillary a 

 low hexagon, h = - 3 , br. II Br — s : 2. Syzygies with an interval of 

 2 — 3 oblique articulations. Br 1 — S discoidal. — Distal p — s with a 

 notch between the 2'" and 3'' segment (a similar condition though not 

 so decided in Sp. 1 too) by which the 2'' segment seems to form a 

 small prominence. For further details as in the following specimens
