212 A. E. Verrili— Marine Fauna of North America. 
ANTHOZOA, 
Keratoisis ornata Verrill, sp. nov. 
Corallum tall (over two feet high), spreading, arboresceatly, 
but distantly and irregularly, branched, the branches spreading, 
often nearly at right angles, elongated, rather slender, gradually 
tapering, giving off, in the same manner, elongated branchlets. 
The branches and branchlets mostly arise from near the proxi- 
mal end of the calcareous joints, but sometimes from the mid- 
dle. The calcareous joints are ivory-white, elongated, round, 
slightly enlarged at the ends, faintly and often indistinctly 
striated longitudinally, appearing smooth to the naked eye, but 
finely granulous under a lens. Chitinous joints golden yellow 
or bronze-color, short, scarcely longer than thick in the larger 
branches, about twice as long as thick in the smaller ones, 
where they become translucent and brownish or amber-color, 
without the metallic luster seen in those of the larger branches. 
The coenenchyma and polyp-cells are mostly absent, but so far 
as can be ascertained from the small patches remaining, the 
coenenchyma is thin, pale yellowish, and filled with rather 
large fusiform spicula; and the -cells are rather distant, 
in the form of somewhat prominent verruce, strengthened by 
rather large projecting spicula. 
ight of tallest specimen, 26 inches; breadth, 18 inches ; 
length of longest undivided branchlets, 12 to 16 inches; diam- 
eter of calcareous joints of main stem (base absent), 35 inch 
(9™™) ; of the larger branches, ‘20 inch (5™™); length of the 
calcareous joints in the larger branches, 1:25 to 1-95 inches (30 
to 48"™, but mostly about 40™™); diameter in smaller branch- 
lets, about ‘06 inch (15™™); length, °75 to 1:25 inches (19 to 
32mm) ; length of chitinous joints of larger branches, ‘10 to 20 
inch (25 to 5™”). 
Two specimens were taken by Mr. Philip Merchant, of the 
schooner Marion, off Sable Island, N. S., in about 250 fathoms, 
on a trawl line. 
_ This is a large and beautiful species of a group formerly con- 
sidered chiefly tropical in habitat. The weiter: or bronzy 
chitinous joints contrast finely with the clear ivory-white 
careous joints. The genus was founded by Professor E. 
Perceval Wright, in 1869, for a species taken in deep water, 
off the coast of Portugal. 
Acanella Normani Verrill,

was brought in by Mr. J. Murphy, from Banquereau, in 
the same region. The species Bviri 4 B
