interiorly; third and fourth brachials (syzygial pair) half again to 

 twice as broad as long, oblong; next three brachials oblong, about 

 twice as broad as long, then becoming wedge-shaped, almost triangu- 

 lar, half again as broad as long, after the proximal third of the arm 

 becoming gradually less obliquely wedge-shaped, though remaining 

 of about the same proportionate length, and in the terminal portion 

 of the arm becoming wedge-shaped, and as long as or longer than 

 broad. The elements of the division series have everted and promi- 

 nent, finely spinous, distal ends ; the brachials have strongly produced 

 and overlapping, finely spinous, distal ends. Syzygies occur between 

 the third and fourth brachials, again between the eleventh and 

 twelfth or twelfth and thirteenth, and distally at intervals of four 

 oblique muscular articulations. 



Disk 13 mm. in diameter, with a few scattered calcareous granules 

 about the central anal tube ; mouth marginal and radial. 



Pd 15 mm. long, slender, with forty joints, all approximately as 

 long as broad; terminal comb arising suddenly, with seven teeth, 

 triangular, longer than broad, basall}^ in apposition, rather longer 

 than the diameter of the joints which bear them, rather strongly 

 incurved; P^ similar, slightly less stout basall}^, equal in length 

 or slightly longer; P, small and weak, (J mm. long; Pg similar, 

 but 5 mm. long (twenty joints) ; P^ 6 mm. or 7 mm. long, consider- 

 ably stouter than the two preceding i)innules, with the distal ends of 

 the joints strongly produced, and bearing a genital gland; following 

 pinnules slightly stouter, with larger genital glands, and slowly 

 increasing in length ; distal pinnules very slender, about 9 mm. long, 

 with about twenty joints, the first two short, then increasing in length 

 to about twice as long as broad and decreasing again in the terminal 

 jDortion. 



Color (in spirits). — White, the arms beyond the basal portion with 

 broad broken lateral lines, and dorsal bands, of violet; cirri white, 

 with occasional bands of light violet.
