Hab. Unrecorded. B.M. 
The specimen to which this specific name has been given 
consists of a small broken portion of a rather massive struc- 
ture—a short branch with four short chief branchlets, on 
different parts of which there are indications of still smaller 
branchlets. In the sum of its characters it differs altogether 
from all other known species, though in many points its close 
affinities with A. californica, V., A. venusta, V., A. miniata, 
Powt., and A. nobilis, K., ave clearly seen. Its thick and 
massive structure, its cyelosystems placed on all sides of its 
branches and not raised above the surface, its few dactylo- 
pores in each system (generally 3 or 4), its rather short thick 
style in the gastropore, and its reddish-orange ochre colour 
are its essential characters, and will serve to mark the species 
with certainty. As the specimen is simply a broken branch, 
the details of the form of the entire cceenosteum must await 
description from a more perfect specimen ; but it is probable 
that it will be found to agree very closely with A. nobilis, K. 
Stylaster pulcher, n. sp. 
Coenosteum of a yellowish vermilion or bright tile-red 
colour, much branched, somewhat flabelliform but very irre- 
gularly so, branches not coalescing, surface very finely marked 
with whitish striations, especially on the basal parts; main 
trunk and branches rather thick, rounded or very slightly 
compressed, regularly diminishing and giving off many short 
branchlets, but these are not very small or delicate ; cyclo- 
systems arranged in two rows on opposite sides of the branches, 
but this is often disturbed, and many are found scattered over 
the surface of the ccenosteum, very few towards the basal 
_ parts of the main trunk, many having given rise to branchlets, 
very variable in size and structure, subcircular or elongate, 
prominent but never pedicellate, about *75 millim. in diameter, 
often much smaller, about 1:25 millim. apart in the same row ; 
dactylopores generally about 8 to 10, frequently less, very 
rarely 11 or 12, small, with minute styles, often unequally 
placed around the gastropore so as to give a varying thickness 
to the pseudosepta; gastropores very deep, rather wide, with 
a distinct short brush-like style; ampulle forming circular 
swellings, rather paler than the axis in colour, about 1 millim. 
in Giameter, placed on all sides of the branchlets, and giving 
them a rough swollen appearance ; many small pores, avout 
the size of the dactylopores, occur scattered over the surface 
of the coenosteum.
