(11) 80 arms about 100 mm. long; cirri 35 — 37 mm. long, composed of 48 — 51 

 segments; Pd 32 mm. long, with about 60 segments; colour nearly white, the cirri and the 

 sides of the rays and arms deep purple. 



. (12) about 85 arms; colour yellow brown dorsally, purple ventrally. 



The preceding specimens are all very uniform ; division series of 2 are very rare ; the 

 proximal pinnules are typically very large and stout basally, tapering gradually and becoming 

 flagellate distally; the distal edges of the segments in the outer half are prominent. 



(13) a young specimen with 17 arms about 40 mm long; two of the rays bear two 

 arms each ; two others bear four arms each, there being one IIBr 4 (3 + 4) series, bearing a 

 IIIBr 2 series internally ; the fifth ray bears one IIBr 4 (3 + 4) series carrying two IIIBr 2 series. 



(14) a young specimen with 14 arms 25 mm. long; one IIBr series is present, bearing 

 two IIIBr 4 (3 + 4) series; the synarthry between the ossicles of the IBr series is just beginning 

 to transform into a pseudosyzygy.

The specimens from Stat. 162 are both young; one, badly broken, is entirely deep purple ; 

 the other, with 14 arms, is deep purple with a broad mediodorsal line of white on the arms. 



The example from Stat. 179 has 20 arms 90 mm. long; there are six IIBr 4 (34-4) 

 series and four IIIBr 2 series present, the latter all internal; the distal edges of the radials 

 are obscurely beaded ; the sides of the division series and rays bear a few irregular spinous 

 processes; the cirri are XVIII, 28 — 33 (usually 30), 25 mm. long; long dorsal spines are 

 developed from the ii th — 1 3 ,h segment onward. 



From Stat. 322 there is a small individual with 16 arms 60 mm. long; five of the six 

 IIBr series are 2 instead of 4 (3 + 4); the cirri are XVII, 27, 17 mm. long; the colour is 

 deep purple.
