the base; the axillaries are longer than broad with a strongly produced distal angle and an 
equally long, but broader, posterior process which rises into a faint rounded median carination ; 
the second brachials are much longer than broad with a faint median carination running their 
entire length; and the following brachials are slightly raised in the mid-dorsal line, the raised 
portion bearing very numerous very fine spines.

The centrodorsal is conical, the sides practically straight, 2.6 mm. in diameter at the 
base and 2.6 mm. from the apex to the interradial border, and is closely set with about one 
hundred cirrus sockets of which about one half appear to be of full size. 
The radials are just visible beyond the rim of the centrodorsal in the median line, but 
extend well up in the angles of the calyx ; their distal angles are slightly separated. 
Viewed perpendicularly to the plane of their dorsal surface the IBr^ are very short and 
band-like, five to six times as broad as long, the proximal and distal borders parallel, the 
distal angles broadly rounded off and finely spinous. If the animal is viewed at right angles 
to the dorsoventral axis the IBr, are seen to be very strongly convex dorsally and, since the 
plane of their mid-dorsal line is at right angles to that of the dorsoventral axis, they appear 
to be bisected by the posterior process of the axillaries. 
The IBr.^ (axillaries) are about as broad as long with very strongly concave sides; as 
a result of the broad rounding off of the distal angles of the IBrj their lateral angles, the 
proximal borders of which are horizontal, overhang for a very considerable distance the distal 
corners of the IBrj so that large rhombic water pores are formed between the IBr series. There 
are no ventrolateral processes on the elements of the IBr series, or on the first two brachials. 
The first brachials are very short, the inner two thirds very narrow and band-like, the 
outer third rapidly increasing in length so that the outer border is from three to four times 
as long as the inner, or the median length; interiorly their bases are not in apposition, and 
their inner borders diverge at somewhat more than a right angle. 
The second brachials are irregularly quadrate, somewhat broader than long: their inner
