The Ckinoids from Dk. S. Hock's Expédition to Japan 1!)14. 125 



Axillary h = '/2 br, rhombical, the proximal angle covcring a 

 part of I Br 1. The axillary is broader than I Br 1. Br-s 1 inside 

 well separated. Arms X, 20 mm.+, but not very much longer. 



?! 10; 4 mm. (a distal, spiny whorl from the 6"' pinnular), P^ 7; 

 2 mm., withont genital gland, P3 7; 2 mm. with a genital gland from 

 the 3'' — the 5* segment. Pg 13; -1 mm. (I'" and 2'' segments short, 

 the other ones long). 



Disk 4 mm. Anal funnel long. 



Sp. 2 (St. 47) C. XXXVII S -11;' 2—4,5 mm. (4'" cirral the 

 longest, L = 3 — 4 X br). R — s concealed. Axillary h = ^/3 br with 

 strongly concave distal margins. Br-s 1 basally contiguous inside, h of 

 the outer border '/2, of the inner one '4 X br. Arms X, 25 mm. 



Pj 7 — 8; 2 mm. (The L of the segments with the exception of 

 the two first and the very last ones 2 — 3 X br), P._, 6; 1,2 mm. P., S; 

 2,2 nmi. with a genital gland, P^ 8; 2,2 mm. Distal p. 14; 4 mm. 



Sp. 3 (St. 47) C. XXXI 9-10; 2,5—3,5 mm. 



Axillary as in the preceding specimens. Arms broken, probably 

 between 20 and 25 mm. 



Pi 8; 3 mm. (3'' segment L = 2'/2, 4"' one L = 372 br) P., 5-6; 

 1,2 — 1,5 mm. P3 7; 2 mm. No pinnules genitally swollen. 



Disk 1,8 mm. Parasitical Myzostomids. 



Sp. 4 (St. 45) C. about XXV on a hemispherical Cd; arranged 

 in two whorls: 9 — 11; 2 — 4,5 mm. The segments very pronouncedly 

 hour-glass-shaped, those before the antepenultimate cirral L = 2 br, 

 antepenultimate segment L= l',2 br. Cirri from the dorsal whorl with 

 very much longer segments (cf. the figure ill), in this case the ter- 

 minal claw and opposing spine are relatively large. 



I Br 1 h = Ve br. Axillary rhombical, h = '/2 br (lower, and with 

 smaller lateral angles than in the preceding specimens). Arms X, 15 

 mm. +. Br-s 1 inside basally contiguous. Syzygies with an interval 

 of 3 oblique articulations. Br-s rather smooth. 



Pj 8; 1,5 mm. P^ 6; 1 mm. P3 7 — 8; 1,8 mm. with a genital 

 gland. Disk 2,5 mm. Anal cone 1,3 mm. 



Sp. 5 (St. 45) C. + XXV 10—11; 2—3 mm. (4'" segment L = + 4 X 

 br). Arms about 15 mm. Pj 0; 1 mm. P, 4; 0,5 mm. or lacking. 

 Disk 1 mm. No gonads developed.
