From St. 53 (1 sp.) 59 (2 sp.) = 3 specimens. 



Sp. 1 (St. 59) Cd 3,5 mm., free dorsal pole 2,5 mm. Cirri XXI. 

 19; 10 — 12 mm. in a single or double whorl. First and 2'' segments 

 short, 3'' cubical, somewhat hour-glass-shaped, 4*'^ a little longer, 5 — 7*'' 

 segments L = 1 ^2 br. Then shortei' segments again with dorsal spines. 

 Penultimate segment L = br. Terminal claw coarse L= 1'2X the 

 foregoing segment. A young cirrus has the 4 — 7"' segments some- 

 what longer, L = 2 X bi'. 



B-s and R-s as in the preceding species. I Br 1 h = V'j bi"- 

 laterally free. I Brax h = V^ bi', the border against II Br 1 a little 

 bent outwards. I Br 2 forms with I Br 1 a small synarthrial tubercle. 

 11 Br:s are 2. 



The arms are XV (or perhaps XVI), partly broken, 65 mm. 

 Primipostaxillaries inside for the most part united. Syzygies 1 — 2, 3 + 4, 

 14+15, 23 + 24 or 13 + 14, 18 + 19, then with an interval of 5 to 6 

 oblique articulations. The proximal part of the arm not quite smooth*. 

 Br:s 1 — 8 discoidal, then oblique joints. Distal segments tolerably short, 

 the margins a little spiny and somewhat bent outward like a collar. 

 16 — 17 segments pro cm (If syzygial pairs are counted as units there 

 are 14) Breadth of arms 1,2 mm. 



Pj— Pc with combs. P, 36—38 (18 T) 9 mm. Teeth rather nar- 

 row, '/2— '/3 of the segment's breadth. P^ + 30 (15— 17T) 6,5 mm., 

 P3— P5 with decreasing length. P^, 22 (12 T) 4.5 mm. Distal p. 17—18; 

 5 — 6 nun.
