L = i '/3 br. Antepenultimate segment L = or somewhat larger than 

 br; last 3 lo 4 segments with a small, dorsal s|)ine. Terminal daw 

 strongly bent, somewhat longer iliaii the proeeding segment. 



K — s appeai'ing as small coi-ner-llaps. I Br 1 h = '/e x bi-, later- 

 ally I'ree, the angle between them about 45°- United with the axillary 

 by syzygy. 1 Br 2 triangular h = '/2X br, with very concave distal 

 sides. Br 1 and 2 rather narrow^ h = '/4 X br, on the outer side 

 twice as broad. Arms X, + 20 mm. The arm-bases fairly smooth. 

 Syzygies. for instance, 3 + 4 . . . 1 1 + 12 . . . 15 + 16 . . distally with an 

 interval of 3 oblique articulations. The longer side of the distal seg- 

 ments L = 2 X br. 20 Br-segments pr cm. (15, if the syzygial pairs 

 arc counted as units). The br of the segments 0,5 mm. 



Pj— P2 wnth a comb. Teeth 8—10. P, 27; 4 mm., P, 23; 3,r, mm. 

 P., 11; 2,5 mm. with a genital gland. Distal p. 14; 4,5 mm. 2'' to 

 4"' piiuiulars somewhat notched on the outer side (especially on P, 

 and P2). The bases of the p — s however smooth because of connec- 

 ting skin. 



Disk smooth, + 2 nun. Mouth central. Cushion-foi-med swel- 

 lings along the ambulacral furrows. Anal funnel bi'oad, coarse, short. 



Sp. 2 (St. 45) P3 — P12 with genital glands. For further details 

 of these as well as the following specimens see the table. 



Sp. 3 (St. 45) P2 very small. Disk 2 mm. 



Sp. 4 (St. 45) I Br 1 h = '/s X br. P.,— P., with genital glands. 



Sp. 5 (St. 45) Disk 3 mm. Sp. 6 (St. 45) Disk 3 mm. Specimens 

 6 — 10 young, more slender individuals. 



Sp. 7 (St. 45) Antepenultimate cirral in the smallest cirri L = 

 1 '/2 X bi'. 1 Bi' 1 bent outwards almost at a right angle. Disk 2,5 mm. 



Sp. 8 (St. 45) Segments somewhat more spiny than in the pre- 

 ceding specimens. 



Sp. 9 (St. 45) — . Sp. 10 (St. 45) I Br 1 h = '/4 x br. Disk 2 mm. 



Sp. 1 1 (St. 42) 1 Br 1 almost completely hidden. Pj with 23 

 segments. Disk thrown off. Basal star visible. 



Sp. 12 (St. 47) Cd 2 mm., h-ee dorsal pole 1,5 mm. IV C, very 

 small. 1 Br 1 h = '/s br. Usually Br .1 + 2, 3 + 4; Pj with 24, Pg with 

 20 segments. The bases of the pinnules with strong genital swellings. 

 Disk 3 mm. Colour brown.
