Ninthly, a new _Glaucus_, of a remarkably slim
body, with short fins, and of a blackish-blue colour. Tenthly, a
_Eucharis N._ In addition to these, no less than eight Crustacea were
taken in the net. In the vicinity of Kamtschatka, the vessel sailed
daily through red masses floating on the surface; on drawing up some of
the water, the pail was found full of red _Calanus_, a line and a half
long, with rough feelers of the same length as the body.

In Kamtschatka we found the Bay of Awatscha poor in Mollusca and
radiated animals, owing probably to the inconsiderable ebb and flood.
The objects most frequently met with, were an ugly little _Turbo_, the
empty shell of which was tenanted by a black _Pagurus_ and a _Balanus_.
A large _Cyanea_ differs from the European _C. ciliata_, in the form of
the stomach. Another Medusa, constituting a new kind of _Sthenonia N._,
was observed; its digestive organs resemble those of the Aurelia; and
about the edge, eight bunches of very long fibres project, provided,
like those of the Physaliae, with two rows of suckers.

The environs of St. Peter and St. Paul, lying under fifty-three degrees
of north latitude, possess an insect Fauna, such as is in Europe only
found in sixty and seventy degrees of latitude; as for instance, in
Lapland and Finland. A great number of species are exactly similar in
both regions; others of the Kamtschatkan insects have been met with
nowhere else, except in Siberia, and a small number is quite peculiar to
the former country. All have not yet been subjected to a diligent
examination, and only the following can be with certainty mentioned.

Firstly, in the North of Europe also, are found: _Pteroloma Forstroemii
Gyllh._, _Nebria arctica Dej._ (_hyperborea Schoenh._), _Blethisa
multipunctata_, _Pelophila borealis_, _Elaphrus lapponicus_ and
_riparius_, _Notiophilus aquaticus_, _Loricera pilicornis_, _Poecilus
lepidus_, _Dyticus circumcinctus_, _Staphylinus maxillosus_, _Buprestis
appendiculata_, _Elater holosericeus_, _Ptilinus pectinicornis_,
_Necrophorus mortuorum_; _Silpha thoracica_, _lapponica_, _opaca_, and
_atrata_; _Strongylus colon_, _Byrrhus albo-punctatus_, _dorsalis_,
_varius_ and _aeneus_; _Hydrophilus scarabaeoides_ and _melanocephalus_;
_Cercyon aquaticum_, _Hister carbonarius_, _Psammodius sabuleti_,
_Trichus fasciatus_, _Oedemera virescens_, _Apoderus Coryli_, _Leptura
trifasciata_, _atra_ and _sanguinosa_, _Lema brunnea_, _Cassida
rubiginosa_, _
