broadly flattened; cirri with 25 — 28 segments of which the longest are 
from two to three times as long as the diameter of the much expanded

The centrodorsal is sharply conical with straight sides, 3.5 mm. in diameter at the base 
and 3.0 mm. from the apex to the interradial border, thickly covered with very numerous 
cirrus sockets. 
The distal border of the radials is even with the rim of the centrodorsal in the median 
line, and is slightly produced — very much less than in most species — in the interradial 
angles; the distal angles al-e slightly separated. 
The IBr, are very short, eight to ten times as broad as the median length; the proximal 
border parallel with the curved distal border of the radials, the distal border on either side 
of the median line convex, nearly parallel with the concave proximal sides of the axillaries. 
In direct lateral view (viewed at right angles to the dorsoventral axis) the IBr, appear almost 
or quite bisected by the posterior process from the axillary. The bases of the IBr, are widely 
free laterally. 
The IBr, (axillaries) are about as broad as long with the anterior angle considerably 
produced ; the lateral angles project somewhat beyond the distal angles of the IBr, so that 
narrow elongate water pores are formed. Neither the IBr, nor the axillaries have ventrolateral 
processes. 
The first brachials are extremely short in the median line, very slightly longer in median 
length, but becoming four to five times as long externally ; their inner sides diverge at approxi- 
mately a right angle. 
The second brachials are longer than broad, rather sharply convex dorsally, with the 
proximal sides rather strongly concave so that a relatively long and narrow process incises the 
first brachials. 
The arms are all broken at the syzygy between the third and fourth brachials. The 
eversion of the distal edges of the brachials and the development of spines along these edges 
are almost obsolete. 
In a smaller specimen the centrodorsal is sharply conical, slightly higher than broad at
