other four regenerating ; there are 1 1 cirrus segments. The other two are 1 o armed young 
with the arms 22 mm. long. 
The individual from Stat. 153 has about 34 arms no mm. long. 
Of the three from Stat. 260 one is large, one small, and 
one very small with only ten arms. 
All of those from Stat. 289 are small; one has 16 arms 
35 mm. long; there are three IIBr 4 (3 + 4) series each bearing 
a IIIBr series of 2 internally; another has 12 arms 25 mm. 
long; there is a single IIBr 4 (3 -|- 4) series bearing a IIIBr 2 
series internally developed; the third has 10 arms 25 mm. long. 
Of the five specimens from Stat. 294 the largest has 
15 arms 30 mm. long; there are two IIBr 4 (3 + 4), series, 
one bearing internally a IIIBr 2 series, the other bearing two 
IIIBr 2 series; another has 12 arms 25 mm. long; there is a 
single IIBr 4 (3 -|- 4) series which bears internally a IIIBr 2 
series; a third has 10 arms 25 mm. long, and the remaining 
two have each 10 arms 15 mm. long. 
The largest specimen from Stat. 305 has about 30 arms 
75 mm. long; the dorsal pole of the centrodorsal is flat, 2 mm. 
in diameter; the cirri are XXI, .12—13, 10 mm. long; another has 30 arms 70 mm. long; 
the cirri are 8 mm. long, composed of 9 — 10 segments; one of the cirri in this example is 
curiously modified (Fig. 2, A); it is composed of 8 segments and measures 5 mm. in length; 
the first three segments are of the normal type, but the following are strongly flattened 
dorsoventrally and greatly broadened, the normal distal dorsal spine occurring at each of the 
distal angles of the segments. The six additional specimens are all small.

Stat. 282. 8°25'.2S., i27°i8'.4E. 27—54 Metres, i Ex. 
This specimen has 20 arms 65 mm. long and the cirri XIII, 14, 8 mm. long; the fifth 
or sixth (usually the former) is a transition segment. 
Except in its smaller size and lesser number of arms this example agrees well with the 
series from the Philippine Islands in the collection of the U. S. National Museum.
