The controdorsal is small, truncated hemispherical, the cirrus sockets arranj^ed in three 
closely crowded alternatiiij; marginal rows; the dorsal pole is small and papillose. 
The cirri are XXIV, 13 — 16, 10 mm. lonjj, recallin<j those of Antcdon petasus but 
smoother dorsally and more slender proximally; the lirst segment is short, the second slightly 
longer, the third as long as broad or slightly longer than broad, the fourth slightly longer 
than the third, the fifth and sixth the longest, twice as long as the proximal diameter; the 
following gradually become laterally composed and, though remaining actually of the same 
length, increase in lateral diameter and become therefore relatively shorter so that the last 
four before the penultimate are slightly longer than broad; in the proximal portion te cirri 
are in lateral view slender, and rounded in cross section ; in the distal half tifey become 
strongly compressed and in lateral view about twice as broad as in the proximal half; there 
are no dorsal processes; the opposing spine is short, subterminal to submedian, its Tjase 
involving only a small part of the dorsal surface of the segment, in height scarcely one third 
the distal diameter of the penultimate segment, directed obliquely forward; the terminal claw 
is somewhat longer than the penultimate segment, stout and strongly curved. 
The radials are just visible beyond the rim of the centrodorsal ; their distal angles 
are separated. 
The IBr, are short about four times as broad as long in the median line, trapezoidal, 
widely separated interradially, the sides making an angle of nearly 120^ with those of 
their neighbors. 
The IBr„ are broadly pentagonal; the anterior angle is appro.ximately 90°; the lateral 
edges are nearly as long as those of the IBrj and make with them an angle of about 120°. 
The synarthrial tubercles are rather prominent, and the elevation is continued somewhat anteriorly 
onto .the axillary. 
The first brachials are short, over twice as broad as long exteriorly, the exterior length 
being rather more than twice as great as the interior; the inner edges are united basally, but 
distally diverge at a very broadly obtuse angle. 
The second brachials are about twice as large as the first, irregularly quadrate. 
The first syzygial pair (composed of the third and fourth brachials) is nearly twice as 
long interiorly as exteriorly, the inequality falling chiefly in the hypozygal, twice as broad as 
long in the median line. 
The next four brachials are slightly wedge-shaped, twice as broad as the greater length, 
then becoming triangular, about as long as broad, and after the proximal quarter of the arm 
wedge-shaped, about as long as broad, and somewhat longer terminally. 
Svzvsies occur between the third and fourth, ninth and tenth and fourteenth and fifteenth 
brachials, and distally at intervals of three oblique muscular articulations. 
Pj is 5.5 mm. long, composed of 15 segments of which the first is short, the second 
longer, the third nearly as long as broad, the fourth slightly longer than broad, and the 
seventh and following about twice as long as broad; the pinnule is small and slender, and 
tapers evenly from the base to a slender and delicate tip; there is a slight swelling on the 
distal edge of the second and third segments.
