brown colour, with brilliant white, sharply defined, areas, and thus closely resembles the 
older darker pieces of Sargassum, which also are thickest covered with Membranipora. 
Antennarius is of the weed colour, and the peculiar white spots on the body evidently 
have a like signification. Even one of the Planarians living in the weed is yellow marked 
with brown. 
“ In the morning when I was out in a boat Radioiarians had been scarce, but in the 
forenoon it fell almost a dead calm, and Murray, going out in the afternoon after it had 
been calm some time, found them on the surface in enormous abundance/'

Ar daylight a spar of pitch pine was picked up and hauled on board. At 9.30 a.m. 
obtained serial temperatures down to 300 fathoms. Cutter was lowered to try the 
current, and jolly-boat for surface collecting. 
Surface Organisms. — Moseley writes : “ The spar of pitch pine was covered with a 
Lepas [ Lepas anatifera, Linne, see Hoek, Zool. pt. 25] in abundance, and numbers of 
the small gulf-weed crab [Nautilograpsiis minutus (Linne), see Miers, Zool. pt. 49]. 
The colour of the crabs here matched admirably with the dark coloured wood and white 
Lepas- shells showing out in relief upon it. But I suspect that they are merely casual 
visitors to such a log, and that their real home is the gulf-weed, the white patches being 
imitative of the Flustra and not Lepas-shells, perhaps of both since a few Lejoas-shells 
are to be met with on the weed. A small brown Nudibraneh ( JEolis ) was abundant on 
the log, and there were plenty of its eggs disposed in small rounded white patches amongst 
the bases of the Lepas- stems. These ova contained embryos in an advanced stage of 
development ; they seemed closely to resemble the embryos of Tergipes figured by 
Selenka. Rome Campanularians were the only other animals on the log, but there were a 
few small Diatoms growing on it. 
“ The tow-net, which for some time past has been almost barren, produced some very 
fine specimens of Phyllosoma, a male Lucifer with spermatophores, larvse of Squilla, 
Nymphon, the yellow coloured gulf-weed Planarian, and several Leptocephali. A 
dolphin was speared with the ‘ grains.’ ”
