Triopa lacer Lovén.

40 to 50 fathoms ; and off Nova Scotia, in 80 to 100 fathoms. 
Scyllea Edwardsii Verrill, sp. nov. 
A large species, the body in extension nearly three inches 
long and half an inch high, with the four dorsal branchiferous 
lobes about equaling in height, or exceeding, the elevation of 
the body. Foot very narrow. Tentacular sheaths stout, 
expanding at the end into a large, flat, rounded lobe, most 
prominent posteriorly ; the small, plicated tentacle projecting 
from a funnel-shaped orifice in its outer anterior margin. 
Branchiferous lobes expanding into a broad, thin, spatulate, or 
paddle-shaped, terminal portion, narrower and thicker toward 
the base, the margins of the thin portions sinuous; the two 
airs far apart; their inner surfaces covered with small, trans- 
back. Anterior surface of tentacular sheath iridescent bluish. 
Along the sides is a row of small white papille, and similar 
ones extend along the white line of the back. Tentacles 
orange, the plications edged with orange-brown, the tips white.
