A (1 1 k c 1 , Zoul. pt. 40).— The sediment which remains after removing t e 
Poraminifera and larger mineral particles is almost entirely composed 
elonging to a few species of Sphseroidea, w ic ma e up 
ha of the whole mass. By far the commonest of these Spumellana is 
( • myosphxra anU which is probably genetically related with the very similar 
form , Cromyomma perspicuum, occurring on the surface at the same Station, 
the other Spumellaria the Discoidea are the most abundant, particularly the spongy 
forms (Spongodiscida, e.g., Spongodiscus, Spongotrochus, Stylotrochus). particularly 
SpongopyU . not des ribed in the Report : it is a bpongodisci 
with a marginal osculum like that of the Porodiscid Ommatodiscus, which also occurs at 
t) _ t , station. In contrast to the large number of Sphseroidea and Discoidea, the 
Pnm ndea and Larcoidea are present only as isolated specimens. 
Very few species of Nassellaim are present, but among them the Botryodea, which are 
re, are rather abundant, especially Botryocdla borealis and Botryopyle 
cribros't. The most common Cyrtoidea are a few cosmopolitan forms, lor examp e, 
CortiutcUa cloth rota, Comutdla cannvlata, and Lithomitra lineata. 
only represented in this deposit by a single rare species, 
Pantopelta icomsjns. 
Ti • Phmodaria are represented by a few remarkable forms, such as bagenoscena 
r inllata, Aulosphan'o. bistemaria , Cannosphtera antarctica, and Conchasma hippuntes ; 
all these, however, are rare.
