Excluding Protozoa, over 150 specimens of invertebrates and fishes were obtained at 
this place, belonging to about 120 species, of which 32 are new to science, including 
representatives of 2 new genera ; 22 of the new species and 1 new genus were not 
obtained elsewhere. From the deeper water (240 fathoms) Q species were obtained, of 
which 5 are new, including representative of 1 new genus ; 2 of the new species and 
the new genus were not obtained elsewhere. One of the new species was taken also only 
in the shallower water (18 fathoms). 
Willemoes-Suhm writes : “ The sandy bottom in 18 fathoms was evidently covered by 
Algee, among which were Corals, Crustacea, and shells. A little green Stenorliynclius was 
specially adapted for life among the Algse ; the Lupea had brighter colours, and Alpheus, 
a compressed little Astacid, made a cracking noise by knocking one finger of its chela 
upon the other. From 240 fathoms a Hyperid was obtained having very remarkable 
appendages to the pereion, enabling it to close up exactly like a ball.” 
Moseley writes : “From 18 fathoms w r e brought up numerous Algae, Halimeda 
caulerpa, &c., one specimen of Acetabularia, great abundance of a green confervoid- 
looking Alga, one melanosperm Pavonaria (?), one red Alga, and abundance of Halophila 
in fruit (that on the reefs in shallow water was not, I think, in fruit).” 
Foraminifera (Brad} 7 , Zool. pt. 22). — The following species of Foraminifera were 
observed during the examination of the deposit from 18 fathoms (Station 172) ; the 
pelagic species, which make up about 6 per cent, of the carbonate of lime present in the 
deposit, are marked thus x : — 
Nubecularia divciricata, Brady. 
„ inflata, Brady. 
,, lucifuga, Def ranee.
