From St. 53 (2), 09 (2) = 4 .specimens. 



Sp. 1 (St. 59) Cd di.seoidal, 4,5 mm , fi-ee dorsal surface 3 mm., 

 h = ],s mm. C. XXIX 31 — 35; 19—21 mm., 3'' and 4"' segments cubical, 

 5th — gth slightly longer, tiien siiorter segments again, 10"' — 12"' segments 

 with a dorsal transverse ridge, 13"' — 1-6*'' witii a 3— pointed prominence, 

 16"' — 24"' witli a double spine then a single dorsal spine. The 

 double prominences sometimes not distinctly separated. Dorsal spine 

 very small, but in side view well bounded, fixed at the middle of the 

 cirral, h = Va of the br of the segment. Opposing spine considerably 

 larger h = \'2 — ^/3 of tlie br of the segment. Terminal claw pointed, 

 curved, about as long as the preceding segment. 



R — s projecting under the margin of Cd. I Br 1 h 'e br, late- 

 rally free. 1 Brax h = \'2 br, the lateral sides bent at a slight angle 

 to the preceding ossicle. A well-developed synarthrial tubercle be- 

 tw^een I Br 1 and 2. II and III Br — s : 2, the later ones on the outer 

 sides. Arms XXVI, broken (probably XXVIII in a complete .specimen). 

 Ex. of syzygies: 3 + 4, 18 + 19, distally with an interval of fO— )9 obli- 

 que articulations. Arms smooth, after Br 9 oblique joints. 



Pj 17; 6 mm.. (Pj on Br 2 from the inner side of a II Brax; 14; 

 6 mm.), P.2 17 — 18; 9,^ mm.. P., 1()-18; 7 — 8 mm. The distal segments 

 of Pg and P3 very long, L = 3 br), in the distal margin serrate. Pa 

 lacking, Pj, = Pg. P, usually absent on the inner side after a III Brax. 

 Distal p. ±20; 7 mm. 



Disk very much incised, smallest diameter 4, largest one 10 

 nun. Colour: red-violet with yellow longitudinal bands. Distally with, 

 yellow and red spots mingled.
