PennatULIL'A (Kolliker, Zool. pt. 2). Station VII. 
Umbellula thomsoni, n.sp. Two specimens ; obtained at no other locality. The larger Trawl/ 
specimen had a stem 3 feet in length, and showed most brilliant 
phosphorescence, which, on being examined with the spectroscope, 
gave a very restricted spectrum, extending from about b to D. 
In the Station-book are noted also: Archaster [_ = Plutonasier] bifrons (?), and 
three specimens of Stichopus (?) sp.
