This list contains the names of 210 species. Of these, however, 30 have not been 
observed as yet in the Malay Archipelago. It seems certain that at least part of them will be found 
there eventually, for these species inhabit the south-eastern part of Asia, which has numerous species 
in common with the said Archipelago. Of course, the same is the case, at least to a certain 
extent, with the Malay Archipelago and the seas of Eastern-Asia (China, Japan, etc.) to the North 
of the region, and of Australia to the South of it. Yet there is an important difference between 
the latter regions and the Malay Archipelago: while they both extend from the tropical and 
sub-tropical regions far into the temperate zone, and, in consequence, are also inhabited by 
several species which are peculiar to the latter, the whole of the Malay Archipelago lies 
below the tropics. Nevertheless, the list of species representing the fauna of the latter region 
combined with that of Southern-Asia contains the names of several species, the distribution of 
which can be followed either into Australia or into the waters of China, Japan, etc. 
When discussing the geographical distribution of the species of Cirripedia, we commonly 
leave out of consideration those species that always are found to live attached to floating 
objects, drift wood, ships’-bottoms, and the like. Their distribution is generally supposed to be a 
very wide one, if not always a cosmopolitan one. In fact, some of these species are observed 
all over the world’s surface, as for example several species of Lefas and Conchoderma; but 
other species of the genus Zefas have a more or less limited distribution, so far as our 
knowledge goes at present. This seems to be the case also with several species of Cirripedia 
that are sometimes found attached to floating objects, but which live also on rocks, stones, 
shells, etc. and are collected even at not quite unimportant depths: Balanus tintinnabulum Linn., 
B. amphitrite Darwin, and 2. amaryllis Darwin are good examples of this case. They have no 
doubt a wide distribution, yet they are observed only in warmer, temperate, and tropical seas. 
Again, we know species that are found on ships’-bottoms, which are also dredged either in 
shallow or in relatively deep water, and have a wide distribution in the temperate zone, but 
which do not seem to be altogether absent from warmer seas. Such species are B. improvisus
