From St. 39 1 1 ), 47 (1) = 2 specimens. 



Sp. 1 (St. 39) Cd discoidal. free dorsal pole 2,5 mm. C. XXIX 

 27-30 (D) 31—38 (V), 16—24 mm. in two close whorls. P^— 3'' seg- 

 ment with a little convex proximal and concave distal margins in 

 lateral view. 4"' and the following segments slowly increasing ta 

 L = br (at the 15* or 20''' segment). No dorsal spine. Opposing spine 

 small, coarse, blunt-ended, h = '/3 of the br of the segment. Terminal 

 claw short, coarse, L = the preceding segment. 



R — s narrow bands. I Br 1 h=' j br, in lateral apposition. 

 I Brax low pentagonal, h = '-g br, with concave distal margins. I Br 

 1 and 2 form a low synarthrial tubercle. II and III Br— s: 2, (III Br — s 

 in 6 cases on the outer sides). Primipostaxillaries united inside. Arms 

 XXVI, 120 mm. The br of Br 1 = 1,6 — 1,8 mm. Br 2 twice as long on 

 the outside. The first 10 Br-segments rectangular, h = ' 2 br, then 

 slightly oblique joints. 



pt- syzygy usually between Br 3 and 4 but often exceptions 

 (see the example). Distally with an interval of 7 — 12 oblique articu- 

 lations. Example of arm-division:
