 From St. 43 (15 sp.), 53 (2( = 17 specimens. 



Sj). 1 (St. 43) Cd low, ai'ched, br = 1,8 mm., free dorsal surface 

 1 mm., somewhat granulated. H of Cd I mm. (fi-om the R — s to the 

 dorsal pole). 



C. XXX 15 — 18; 3,5 — 5 mm. in two close, alternating whorls. I''' 

 segment shorter than long, 2'' and 3'' cubical, 4"' L = 1 V* X br, then 

 slowly decreasing. 5"' — 7"' (or 8"') segment with a low, transverse, cur- 

 ved crista which from the 8"' cirral concentrates to a small, simple 

 dorsal tubercle. Opposing spine pointed, rather large (h = '/2 of the br 

 of the segment). Terminal claw curved, rather stout, length about the 

 same as the preceding segment. The whole cirrus rather stout. 



R — s almost concealed at the middle by Cd, a little tongue-like 

 in the corners. I Br-s 1 baso-laterally contiguous or free, h =+1/4 

 br, with a small medio-dorsal tubercle. Axillary h = ^/4 br, almost 

 hexagonal with a low, synarthrial, longitudial crista (rather slightly 

 bordered) in the proximal ^/3. Arms X, 30 — 35 mm., smooth. Br-s 1 

 united inwardly to ^/3. Br 2 on the outside twice as broad. Br 1 

 and 2 with a slight synarthrial prominence similar to that of the 1 

 Br series. Ex of syzygies: 3 + 4, 9+10.. distally with an interval of 

 3 oblique articulations. The proximal segments rather long. 



Pj and Pa absent. Pj 12: 6, .5 mm. (P* segment short, 2'' a little 

 longer than broad, 3'' L = 2 br, 4'" and 5*'' segment L = 3 — 4 X br 

 slender, at the ends somewhat widened. From the 3'' segment the 

 distal ends are indistinctly collar-shaped and have spiny borders), P,, 

 () mm. P3 11; 5 mm. P^ 10; 3,2 mm. with a genital gland and con- 

 siderably shorter segments. Distal p-s. 10; 5,5 mm. (1"*', 2'' and the 

 last segments short, the other ones L = 2 br). 



Disk without calcareous granules, incised, longest diameter 4, 

 shortest 2,5 mm. Anal cone long, + 2 mm. 



Cirri white, the arms red-violet. 



Sp. 2 (St. 43) The size of the disk as before. Anal cone 1,5 

 mm. Colour a little lighter: red-grey with a light, dorsal, longitudinal 

 band. For further details compare the table.
