From St. 45 (3 sp.), 51 (1), 59 (1), 60 (1) = 6 specimens. 



Sp. 1 (St. 51) Cd thickly discoidal, 10 mm., free dorsal pole 

 5 mm., flat with somewhat i-aised margins. 



C. XLII 27-28 (D) 30—32 (V) 35-40 mm. in 2 to 3 whorls. 

 P' and 2" segment shorter than long, 3'' and 4"" cubical, 5"' — 9"' some- 

 what longer than broad to L = 1 '/2 X br. Dorsal spine from the 11"' 

 segment (Length of this segment = br). From about the 15"' segment 

 L = ^2 X br. Dorsal spines and opposing spine very small, ii = V/6 X 

 the breadth of the segment. Terminal claw L =^^ 1 \4 X preceding seg- 

 ment. 



I Br 1 almost completely hidden by Cd. I Brax pentagonal h =^/2 br, 

 distal margins weakly concave. The disk visible in the narrow inter- 

 spaces between the outer sides of the II Br:s and I Brax. II Br:s 

 are 4 (3 + 4). II Br 1 and 2 with distinct synarihrial tubercle. Primi- 

 postaxillaries completely grown together inside. From II Br 2 the distal 

 margins of the segments are somewhat collar-shaped, bent outw'ards 

 and provided with small spines. Ill Br:s are 2 (1 — 2) in 8 cases 

 of 13. IV Br:s: 4 (in all 13 cases). Arms XLVI 130 mm. Br 1-7
