From St. 50: 1 specimen. 



»S/j. i Cd 3 mm., free dorsaf pole 2 mm., flattened, with a some- 

 what arched dorsal surface. 



C. XIX 19 — 21; 11 — \■^ mm. in a single or double whorl, l""' 3'' 

 segments short, 4"' — 7* L = 1 '/2 — 2 the median br, like the following 

 cirrals strongly hour-glass-shaped. The distal segments shorter. Ante- 

 penultimate one not veiy much longer than broad (L = 1'/^ br). 14"' — 

 18*'^ segments less swollen at the ends. Opposing spine h = '3 of the 

 br of the segment. Terminal claw somewhat longer than the preceding 

 segment. 



R — s nearly concealed, the visible border adorned with small 

 knots. I Br 1 + 2 with a weak median prominence. The arm-bases 

 smooth, without longitudinal prominences as in En. variegutus. A pro- 

 minence between Br 2 and 3 formed in the oblique articulation on 

 the right. A similar knot on the left between Br 4 and 5, and one 

 more on the right between Br 5 and 6, then less pronounced. Arms \\ 

 broken. Breadth of Br 1:1,9 mm. Ex. of Syzygies: 3 + 4, 8 + 9... 

 After Br 10 oblique articulations. Out to Br 4 small, ventro-latei-al 

 rows of knots. 



Pi 10; 4 mm. P, 10; 4 mm. P^ 10; 7,5 mm. P^ 11; 8 nmi. These 

 p. extraordinarily coarse and thick, sharply triangular; 3'' segment on 

 Pj and P.^ about cubical. The distal segments, L = P 4 br, without 

 distal, spiny borders. P,, and P3 much more slender, the latter 17; 

 8 mm. L of the segment 272 — 3 X br. 



Disk thrown off, probably about 3 mm. Colour yellow-brown. 



This specimen is closest to Eh. indivisus, though the longest cir- 

 rals are rather short to belong to this species. Nevertheless it has
