Bay, Petit Bot, Moulin Houet Bay, and Fermain Bay. 
Herm, in its western part, is like the first district of Guernsey ; in 
’ its eastern part it resembles the second district. 
Sark and Jethou are wholly like the second district of Guernsey. 
Jersey has a much more extensive Insect-Fauna than is afforded by 
all the other Islands, and it may also be divided into two districts. 
The first district corresponds with the lowlands of Guernsey, and 
contains St. Ouen’s Bay, St. Aubyn’s Bay, Granville Bay, and St. Ca- 
therine’s Bay. 
The second district is like the second district of Guernsey, and 
includes Rozelle Harbour, Boulay Bay, Gréve de Lecq, and others 
which I had not an opportunity of visiting. 
Gréve de Lecq and St. Peter’s Valley, which leads to St. Aubyn’s 
Bay, are well wooded, and when they are thoroughly investigated the 
present Fauna of the Island will probably be much increased. 
Alderney, with the exception of Braye Road and Corbelets Harbour, 
resembles the second district of Guernsey. 
The coast about St. Malo consists chiefly of low, sandy plains, and 
the Fauna, in the neighbourhood of the sea, is to some extent like 
that of the first division of Jersey and of Guernsey ; at a short dis- 
tance inland several continental forms appear, and these have migrated 
northward or westward thus far, but do not extend to the Channel 
Islands. 
ARACHNIDA. 
I am indebted to the kindness of Mr. Blackwall for the names of the 
species here mentioned. These species indicate two distinct Faunas 
of the Channel Islands, one much earlier than the other. Tlie first 
Fauna is represented by the ground-spiders, the Lycos, the Drassi 
and the Dysdere ; these are very plentiful, and occur under nearly 
all the large loose stones ; they are especially abundant in Guernsey 
and in Sark, and, as the surface of the isles is gradually diminishing, 
the spiders may have become more and more crowded thereon. The 
species of the second Fauna are of comparatively recent diffusion, 
and some of them seem to have been lately introduced. This Fauna 
is most prevalent in Jersey, and is represented by the Epeire, the 
Thowisi, and the Theridiona. The Epeire are most numerous along 
St. Ouen’s Bay. The only specimen of Thomisus citreus seen was in 
a garden at Rozelle Harbour ; this spider is sometimes yellow, some- 
times white; the yellow variety frequents yellow flowers, and the
