cies of Pteropodes, closely allied to the _Cliodora_;
a small and remarkable Hyaloea; two new _Janthinae_; _Firola hyalina_,
_Pyrosoma atlanticum_, _Salpa coerulescens_, and another unknown;
_Porpita glandifera_, and a new species of globular form; a _Velella_;
two new species of Acalephes, of the same family as the _Diphyes_; and
further _Pelagia panopyra_, and two other very small species. When the
sea was a little agitated on the Brazilian coast, we frequently saw the
large sea-bladder floating on the surface; here we also caught with our
net a new species of small _Hyaloea_, and of the fin-footed _Steira_,
which approaches the nearest to the _Limacina_.

Brazil has lately been visited by eminent naturalists, who have spent
years in the country, and have travelled through it in every direction;
we are therefore bound to suppress the few detached observations we were
able to make during the short space of four weeks.

Captain Von Kotzebue having frequently sent his people to fish in the
Bay of Boto Fogo, we enriched our collection by thirty-two kinds of
fish, the greater part of which were very similar to those already
described as tenants of the Atlantic, but still differing from them in
some respects.

How abundant the insects of Brazil are is generally known, particularly
in the warm and moist lands along the coast, in the vicinity of Rio
Janeiro. Few of them crawl on the ground; the greater part of them live
on the leaves and fruits, or under the bark of trees, in flowers, and in
the spongy excrescences of the trees. Among the coleoptera, the
_Stachylinus_ is a rarity: the white-winged _Cicindela nivea_ of Kirby
is to be found in great abundance on the sand of the beach, which is of
the same colour as itself; the _Cic. nodicornis_ and _angusticollis
Dej._ on the other hand, frequent the paths in the forests. _Cosnania_,
which supplies the place of our _Elaphrus_, is found among the grass by
the side of brooks. The little animals of the _Plochionus_ and
_Coptodera_ species climb, by means of their indented claws, along the
moss on the trunks of the trees: their numbers, in these extensive
forests, must be immense. Of the _Cantharis_, the number is small; the
strongest of which is the _Cantharis flavipes_ F. the descriptions of
which vary, so that it may still be doubted whether we have a correct
account of it. To show the proportion of the numerous subdivisions which
we observed in the different genera, it will b
