Urticina nodosa were attached, their basal margins having, in 
each case, united around the axis, which is small and round. 
The uninjured portion is 125 inches long; breadth across 
largest alee, 60; peduncle, to ale, 450; to first zodids, 3°20; 
breadth of largest alee, 50; height, without polyps, 33; length 
of their acute marginal lobes, ‘10; diameter of peduncle, ‘30;

Anthomastus, gen. nov. 
Aleyonarian forming a large rounded polypiferous mass, 
raised on a short, stout, barren peduncle, Polyps few, very 
large, spiculose, entirely retractile into 8-rayed cells. Rudi- 
Sids numerous, minute, scattered between the 
polyps. Ccoenenchyma abundant, firm, finely spiculose. 
Anthomastus grandiflorus, sp. nov. : 
Corallum broadly capitate, surface finely granulose ; polyp- 
cells not prominent. Peduncle, 50™ broad, 30 high ; polyp- 
iferous summit, 82 broad, 30 thick; expanded polyps, 36 long ; 
8 in diameter; 25-28™™ (1-11 inch) across tentacles. Spicula 
of surface minute, rough stellate and capitate; beneath the sur- 
face are long slender spicula, and slender fusiform ones are 
abundant in the tentacles and pinnz. Color, deep cherry-red. 
Off Sable Island, N. S., in about 250 fathoms, schooner Marion 
(coll. Newcomb). Two specimens were obtained. 
Acanthogorgia armata, sp. nov. 
Corallum slender, flexible, much and irregularly branched, 
somewhat in a plane, the branches occasionally uniting. ce- 
-nenchyma thin, filled with conspicuous, white, rough, curved, 
fusiform spicula. Polyp-cells very much elongated, the length 
six to eight times the diameter, often curved, clavate, or capl- 
tate, smallest at base and suddenly enlarged near the summit, 
which is surmounted by eight groups of long, divergent, por? 
spicula; sides of polyp-cells with eight low ridges, covered wit 
elongated spicula, having an irregular chevroned arrangement. 
Height, about 8 inches; breadth, 6; length of cells, 5%™ to 
8mm; their diameter at base, 8 to 1™™; at summit, 1 to 15" 
Color, ash-gray ; axis, yellowish-brown. : 
Off Nova Scotia, 300 fathoms, Capt. T. Goodwin (sch. Elisha 
Crowell). A second specimen from off George’s Bank, 10 
about 220 fathoms, Capt. Anderson (schooner Alice G. W onson). 
Keratoisis ornata Verrill. 
Of this species, described in the last number of this Journal, 
another specimen, taken with the two preceding, has been re- 
ceived from Mr. Geo. K. Allen, of the schooner “ Marion.” This 
has the coonenchyma and polyps upon it, and is considerably 
taller, but the joints lack the golden color, and are plain 
rown. The polyp-cells are pale salmon, prominent, elongated,
