approaching the condition described and figured by Carpenter; 
the cirri are XX, 25—28, 15 mm. long. 
July 27,1907. One specimen with twenty-four arms 60 mm. 
long; all the IIBr series are present, 4 (3 — 4); four UIBr 
series of 2 are present, three developed internally, one externally; 
the cirri are XX, 25—30, 15 mm. long. 
November 27, 1907. One specimen with sixteen arms 
70 mm. long; six IIBr series of 4 (3 + 4) are present, but no 
IIIBr series; the cirri are XXII, 30, the transition joint being 
usually the eighth. 
January 9, 1908. One specimen. 
It will be seen that these specimens agree closely with Car- 
penter's description of fluctuans, except that the brachials are 
oblong distally; moreover, they all agree among themselves, and 
with Philippine specimens. I at first followed Carpenter's lead 
and considered them, as he did his own '/uctuans”, as belonging 
to Bell's previously described e/egans; but when I examined the 
collections made by the Gazelle” in northwestern Australia, I 
found that I was wrong, for in it there are specimens of what 
is undoubtedly true elegans, which agree with Bell's diagnosis, 
and have much longer and more robust cirri than any of these 
specimens, with more numerous joints. Judging from the material 
at hand, elegans and fluctuans are both perfectly good species, and 
there is not the slightest difficulty in differentiating them.
