odorsal is flattened hemispherical, the dorsal pole more or less thickly covered 

 with rounded tubercles. which beconie smaller centrally: the cirrus sockets are arranged in one 

 irregular crowded rows. 



The cirri are X XX, t2— [6, 7 mm. to 11 mm. long, extremely slender, very slightly 



tapering gradually to a sharp point in thé distal fourth, composed of extremely long 



lents with greatly swollen articulations, especially in the proximal portion;.the first segmenl 



is very short, the second nearly as long as broad, the third from two and one half to three 



as long as the diameter of the expanded distal end, and the following about tour times 



the diameter of the greatly expanded distal ends, which are about twice as broad 



in iateral view as the central portion of the segments; bevond the fifth-eight the expansion 



of the distal ends of the segments gradually decreases, and the Iateral diameter of the segments 



after the tenth gradually decreases to the sharp tip; there is no oppositie spine; the terminal 



claw is very slender, and straight. 



The distal edge of the radials is even with the rim of the centrodorsal, and sometimes 

 bears a few tubercles toward the interradial angles of the calyx; the distal interradial angles 

 are slightly separated. 



The IBrj are very short, about four times as broad as long, twice as long laterally 

 as in the median line; the Iateral edges are parallel, or converge slightly; they make an 

 about 90 - with the Iateral edges of the adjacent IBr,, and are not in contact basally; 

 the proximal and distal edges are broadly thickened, the proximal more broadly than the 

 distal, and very finely spinous; as a result of this thickening of the proximal and distal edges 

 the Iateral have a rounded notch. 



The i; are rhombic, all the sides moderately concave, with truncated Iateral 



angles, from half again to twice as broad as long; the Iateral angles are slightly prodi 

 ontward and downward in rounded lateroposterior processes; the truncated ends of the Iateral 

 angles are about as long as the median length of the IBr,; all the borders are slightly everted 

 and very finely spinous. 



The to arms are from 20 mm. to p> mm. long, and exceedingly slender; the brachials 



elongate, slightly constricted centrally, this condition increasing distally, and practically 



oth, with no production of the distal edges. Syzygies occur between the third and fourth 



brachials, again between the ninth an I tenth and fourteenth and fifteenth, and distally al intervals 



of I lique muscular articulations. 



1' is from 3.5 mm. to \ mm. long, and tapers evenly from the base to the tip; it is 

 composed of 9 -11 segments of which the firsl is twice as broad as long, the second half 



oad, the third twia one as broad, and the remainder from two and
