From 8i. ;]2 ( 1 1. ;{7 (1) = 2 specimens. 



Sp. 1 (St. 32) (\\ low. hluiitly conical. (', XXXII 10—18 (usu- 

 ally 17 — IS). 1»— 11 mm. (The dorsal ('. with 10 segments. 2 nun). 

 I''' and 2'' segments short, then the L = 2 — 2'/2 br. The .segments 

 distally much broadei', not hour-glass-shaped. No dorsal spine. Ante- 

 penultimate segment L = P 4br. Penultimate segment L = 1' s br. with 

 an opposing spine, h = '3 of the br of the segment. Terminal claw 

 slightly curved, somewhat shorter than the preceding segment. 



R— s not very visible. I Br I h = '/4 br, a little narrower at 

 the middle because of the slightly backwards directed synarthrial 

 tubercle on I Brax. I Br 2 L = br, rhombic, with a long, low carina- 

 tion on the synarthrial tubercle, the distal angle pi'olonged. Arms X, 

 + 40 mm. Br — s 1 basallj^ united inside; Br 2 considerably longer than 

 the preceding ossicle, with a proximal border of the same form as in 

 I Br 2, inside widely separated. p]x. of syzygies: 3 + 4, 9 + 10, 14+15 

 etc. with an interval of about 3 oblique articulations. The distal parts 

 of the arms smooth, 



P, 14—15; 5,5-0 mm. P., 14-15; 0— (1,5 mm, P3 13: (3 mm. 

 All these p-s very slender, the two first segments short, the following 

 ones L = 3 br. P^ 8 — 11; 4 mm. with a genital gland. Distal p-s 1(5; 

 ti,.') mm. 



Disk without calcareous granules, 4,8 mm. Anal cone 2.7 mm. 

 Colour: arms white with red transverse bands. 



Sp. 2 (St. 37) C. XXXVllI 10— IG; 3—8 mm. Arms X, 37 mm. 



Pi 12; 5,.^ mm. P, 11; 5 nnii. P, 10. 5 mm. P, 10, with a ge- 

 nital gland from the 3'— (!"' segment. Distal p. -[- 15; 5,5 mm. 



On account of the few segments of P, and Pg and the relatively 

 short P.J the above-desci'ibed specimens appear to come next to /. nui- 

 pornenc'., previously found at Hongkong. /. adresline is a not very dif- 

 ferent species from south Japan. It is distinguished by some more
