Sp. 1. Cd thickly discoidal (h = 1,.^ mm.) with raised margins 

 round the free doi'sal surface, the diameter of wiiicli is 2 mm. — C. 

 XXVI 34—38; 10 — IS mm. in two whorls. The 12 first segments: L 

 about '2 — ^/3 bi', the following ones similar or a little shorter. The 

 distal liait of the cirrus with a low transverse ribbon, which is indis- 

 tinctly (or not at all) divided into two tubercles (slightly projecting in 

 lateral view). Opposing spine: h = '2 of the br of the segment. Ter- 

 minal claw coarse, blunt-ended, L about the same as the pi'eceding 

 segment. 



R— s h = ' 4 br, most apparent in the corners, baso-laterally 

 united. I Br I h = '3 br, laterally free, forming with 1 Brax' a distinct 

 synarthrial tubercle. I Brax h = '^,3 br, pentagonal. A ventro-lateral 

 l)rominenee on each ossicle from I Br 1 — Br 1, largest on II Br 1, 

 where it occupies the whole side of (he ossicle and reaches '5 of 

 the lateral h of the segment. II and 111 Br — s: 2 (the latter ones on 

 the outer sides). Primipostaxillaries basally united inside. Arms XXVT, 

 90 mm. Syzygies: 3 + 4, 12 + 13, distally whh an interval of 7 (— 10>
