508 BULLETIN 82, UNITED STATES NATIONAL MUSEUM VOLUME 1 



spine is terminally situated, triangular, about equal in height to the diameter of the 

 penultimate segment, arising from the entire dorsal surface of that segment. The 

 terminal claw is stout basally, slender distally, strongly curved, and longer than the 

 penidtimatc segment. Botli the opposing spine and the terminal claw arc rather 

 disproportionately large. 



The ends of the basal rays are visible, delimiting tlie deep subradial clefts. 



The radials arc short, with the distal edge fringed with spines. The IBr, are 

 short, about 4 tunes as broad as long, with the posterior border strongly everted and 

 very spinous and the anterior edge incised by a posterior projection from the axillary. 

 The IBro (axillaries) are rhombic, about twice as broad as long, with all the sides 

 everted and very spinous. 



The 10 deep laterally compressed arms are apparently about 150 mm. long. The 

 first brachials arc short, rather longer exteriorly than interiorly where they are united 

 in their proximal half above the anterior angle of the axillary, with the anterior border 

 incised, and with the posterior border everted and spinous. The second brachials 

 are larger, irregularly quadrate, with the anterior and posterior borders everted and 

 spinous. The first syzygial pair (composed of the third and fourth brachials) is about 

 as long as broad, slightly longer interiorly than exteriorly, with the anterior and posterior 

 borders and the syzygial line spinous. The following 5 segments are oblong, about 

 half again as broad as long, with both edges everted and standing up verticall}^ as a 

 row of fine thickly set spines. The following brachials ai'e oblicjuely wedge-shaped, 

 about as long as broad, gradually becoming more elongate distaUy, at the extreme tip 

 of the arm being oblong and twice as long as broad. All of the brachials have over- 

 lapping spinous ends. 



Syzygies occur between brachials 3+4, 9 + 10, and 14 + 15, and distally at intervals 

 of from 2 to 5 (usually 3 or 4) muscular articulations. 



All the pinnules, especially the lower, are very slender. P, is 8 mm. long with 

 22 segments, of which the first 3 are about as long as broad with the corners cut away, 

 the next 2 are progressively longer and more slender, and the remainder are greatly 

 elongated and very slender. Pj is 10 mm. long, slightly stouter than P, but with the 

 same number of segments which are similarly proportioned. The following pinnules 

 become progi-essively stouter and shorter, with shorter segments, Pe being 7 mm. long 

 with 17 segments, of which the first is short, the second is about as long as broad, the 

 third and following are about twice as long as broad, and the few last become more 

 elongate and very^ slender. The distal pinnules are 15 mm. long with the fnst 2 seg- 

 ments rather markedly expanded, the first short, wedge-shaped, the second strongly 

 trapezoidal, about as long as its basal width, and the remainder becoming progressively 

 elongated with somewhat swollen articulations and with one or two long forward project- 

 ing spines on the distal end.
