4 (3 + 4); the centrodorsal is pentagonal, very slightly raised above the surface of the radials; 
a single slender cirrus, lo mm. long with 14 segments, remains. 
Of the 17 specimens from Stat. 89 the largest has 39 arms iii mm. long anteriorly, 
70 mm. long posteriorly; all the division series are 4 (3 -f- 4); an e.xternal IIIBr series is missing-, 
the centrodorsal is small, with the dorsal pole 1.5 mm. in diameter; the cirri are XII, 15, 9 mm. 
long, somewhat compressed distally. Another has 28 arms the anterior i 20 mm. and the posterior 
55 mm. in length; the former are excessively attenuated; the cirri are XII, very small and 
weak, 6 mm. to 7 mm. long with 12 — 13 segments. A third has 28 arms, the anterior 90 mm. 
the posterior 55 mm. in length; of the IIBr series nine are 2, the remaining one being 4 (3 + 4); 
all of the other division series are 4 (3 + 4); the cirri are X, with some additional rudimentary, 
compressed distally_j^ 8 mm. to 9 mm. long. A fourth has 22 arms 130 mm. long, very attenuated; 
five of the IIBr series are 2, and five are 4 (3 + 4); the other division series are all 4 (3 + 4); 
although the arms are much longer, the calyx is the same size as in the preceding; there are 
X interradial cirri, 8 mm. long, slender, with 12 segments. Of the remainder three have exactly 
40 arms, all the IIIBr series being present, four others have 37, 33, 32 and 25 arms respectively, 
five are small, and one is an 11 -armed young. 
The individual from Stat. 149 has 36 arms iio mm. long; all the IIBr series are 2; 
one of the IIIBr series is 2, the others 4(3 + 4); the centrodorsal is greatly reduced, pentalobate, 
bearing at the tip of one of the lobes a single cirrus 9 mm. long with 14 segments. 
The example from the reef at Stat. 209 has 42 arms 95 mm. long; five of the IIBr 
series are 2 ; there are VII cirri. 
That from Stat. 273 has 36 arms 100 mm. long; there are two small cirri and several stumps. 
The larger specimen from Stat. 322 has 49 arms 130 mm. long; all of the IIIBr series 
are present; of the IIBr series six are 2 and four are 4 (3-1-4), the latter all on two rays-, 
the centrodorsal is greatly reduced, small and sharply stellate; the rays and division series are 
broad, and are in close lateral apposition and sharply flattened against each other; the smaller 
has three of the rays undergoing adolescent autotomy; one partially developed cirrus remains 
on an irregularly pentagonal centrodorsal. 
The example from Saleyer has 40 arms 80 mm. long ; one I\'Br series is present, and 
one IIIBr series is lacking; all the division series are 4 (3 -f- 4) ; there are V cirri, and several 
small stumps.
