1 8 mm. long; the first segment is very short, the second from one half again to twice as long 
as the median diameter, the third from two' and one half to three times as long as the median 
diameter, the fourth and following about four times as long as the median diameter; after the 
eighth the segments slowly become shorter so that the antepenultimate is little, if any, longer 
than broad; the penultimate segment is small, wedge-shaped, about half the size of the ante- 
penultimate; the opposing spine is small, subterminal ; the longer earlier segments are moderately 
constricted centrally, with expanded and slightly overlapping ends; the shorter terminal have 
straighter dorsal and ventral profiles so that in lateral view the cirri appear to broaden just at 
the tip; there may be a slightly marked transition segment at about the eighth. 
The distal border of the radials is even with the rim of the centrodorsal. 
The IBr, are verv short, about four times as broad as the lateral length, which is about 
twice the median length; the lateral edges are concave; the}- are just in apposition basally, 
but diverge from each other in the angles of the calyx at an obtuse angle of about i 20°. 
The IBr, (axillaries) are slighdy broader than long, very widely separated; the lateral 
edges are about as long as those of the IBr^, concave, diverging outward at appro.ximately a 
right angle to each other; the anterior sides are approximateh^ at right angles to each other, 
nearly straight; the anterior angle is only very slightly and broadly produced; a rounded median 
posterior projection incises the IBrj. 
The arms are all broken; the size appears to be about that of an average Antcdon 
mediterranea. 
The first brachial is very short, twice as long exteriorly as interiorly, the median length 
about the same as the internal ; the proximal third of the inner borders are united, but the 
distal two thirds diverge almost in a straight line. 
The second brachial is much larger, irregularly quadrate. 
The structure of the arms is essentially the same as that of Antcdon mediterranea. 
Pj is from 13.5 mm. to 16 mm. long, composed of 18 — 21 segments, moderately slender 
and tapering evenly from the base to the delicate tip ; the first segment is not quite so long 
as broad, the second decreases slightly in diameter distally and is about as long as the proximal 
diameter, the third is between two and one half and three times as long as broad, and the 
following are somewhat over three times as long as broad, becoming more elongate distally; 
the segments have the whole surface very finely spinous, and the outer have very finely spinous 
distal ends; the articulations are very slightly swollen. 
Pfl is .similar to Pj, but is not quite so long. 
Pj is 7 mm. long with 14 — 15 segments, much more slender than Pj but otherwise similar. 
P., is 5 mm. long with 1 1 segments, slender and weak, all but the two basal segments 
much elongated. 
Pj is 5 mm. long with 10 segments, slender and weak, similar to P„ but more slender 
beyond the third segment. 
P, is 6 mm. long with 13 segments, slightly stouter than P^ with slightly shorter segments. 
P(. is 7.5 mm. long with 14 segments, similar to P^, but the component segments are 
slightly shorter with more expanded ends.
