 specimen is like that figured by Sars for D. velifer.

This species has been found, for the first time, upon the American 

 coast, by Mr. J. H. Emerton, who discovered it at Salem, Mass., tliis 

 season. He has kindly sent me a specimen and a colored drawing of the 

 species, which he liad already determined. The specimen agrees very 

 closely with Sars's description and figures, both in external characters 

 and in dentition, but not so well with those of Alder and Hancock. 



ANTHOZOA. 



Bolocera multicoriiis, sp. nov. 



A large, handsome species, broad and low, with a multitude of mod- 

 erate-sized tentacles, crowded in many rows, and covering the greater 

 part of the disk. Column smooth, very short ; in our specimen the disk 

 was so expanded that the margin was on a level with the base ; a smooth 

 rim below the bases of the tentacles. Tentacles very numerous (several 

 hundred), crowded in twenty or more indistinct, close, concentric rows, 

 which entirely cover and conceal the disk, except a narrow, naked zone 

 around the mouth ; they are changeable iu form, often cylindrical and 

 blunt at tip, at other times fusiform, clavate, or swollen in any part, 

 their length nearly equal in extension, and mostly less than a fifth of 

 the diameter of the disk, or 14""" to 18""". The disk, as expanded, is reg- 

 ularly convex, and the specimen showed no inclination to contract or 

 withdraw its tentacles. Mouth with a distinct, gonidial groove at each 

 end, bordered by a large fold or lobe on each side; sides of mouth with 

 numerous irregular lobes or folds and wrinkles. Color of body and 

 tentacles nearly uniform bright red-lead color or orange-scarlet ; mouth- 

 folds a deeper tint of the same color. 



Diameter of expanded disk, about 3.75 inches, or 194'"'" 5 height at 

 center, 30""" to 33'""^. 



One specimen only, dredged off Cape Cod, in 45 fathoms, shelly bot- 

 tom, 1879 (U. S. Fish Commission). 



Edwardsia pallida, sj). nov. 



A long, slender, soft, flaccid, whitish species. Column smooth, desti- 

 tute of any investment, but sometimes with grains of sand, slightly 

 adherent; surface faintly longitudinally sulcated, and sometimes finely 

 wrinkled transversely. The form is somewhat changeable, usually much 

 elongated, nearly cylindrical, but often tapered at the posterior end. 

 Tentacles about twenty-four, slender, the length about twice the diameter 

 of the body, of nearly uniform diameter to near the tip, translucent 

 whitish, often with a pale olive-green central line, interrupted by a line 

 of opaque white ?pots, often ten to twelve on a tentacle, or sometimes
