This species is closely allied to the Acanella arbuscula (Johnson) Gray, de- 
scribed from off Madeira, in 1862. It may, in fact, ultimately prove identical 
when the specimens can be directly compared. The figure of A. arbuscula 
indicates a more diffusely branched form, with more slender branches and 
branchlets. The calicles, also, judging from the figure, are different in form, 
but this might be largely due to distortion in drying. The Arctic form de- 
scribed by “Nera under this name is evidently identical with our species, 
but the use of the same name was, apparently, accidental, as he did not refer 
to Johnson’s species. 
From the Bay of Yeddo, Japan, I have several specimens of an Acanella 
without the ccenenchyma, which I cannot distinguish by the axis alone from 
A. Normani. They were collected by Professor E. 8. Morse.

Loosely and not very abundantly branched, the branches arising from the 
horny joints, sometimes singly, sometimes two or three from one joint, but not 
forming whorls in any of the specimens examined. The branches are often 
crooked, slender; and usually spread widely at the base. The calcareous joints 
are long, slender, translucent white, distinctly grooved, and solid, in both the 
larger and smaller branches examined; the horny ones are short, dark brown 
or brownish yellow. The calicles are decidedly swollen at the base, and usu- 
ally broader than the small branches on which they are obliquely set; they 
usually taper distally, and the slightly expanded margin is armed with eight 
large, sharp, spinous spicula, which are minutely warted or spinulated over 
the whole surface. Below the margin the calicles are covered with numerous 
and crowded, much smaller, slender, finely warted spicula, which are arranged 
obliquely or somewhat spirally below the middle. The canenchyma is 
very thin; near the calicles, and especially near the ends of the branches, the
