Spec. 3. Geophilus acuminatus. | 
G. corpore toto ferrugineo antice sensim angustiore, capite an- 
ticé pedibusque dilutioribus. 
Long. Corp. 14 unc. 
Habitat inter muscos rarior. 
Mus. Nostr. 
I first observed this interesting species on Roborough Down, 
near Flymouth, under a stone, and was afterwards favoured by 
Mr. Sowerby with several living specimens, which he received 
along with some moss. It has once occurred in Battersea fields 
amongst moss. 
'The antennz were of equal diameter throughout. The ante- 
rior part of the head paler than the legs, which are slightly paler 
than the back. 
Observation. To this division of the genus Geophilus, Scolo- 
pendra electrica of authors with two other indigenous and some 
exotic species belong; but as I have not had opportunities of ex- 
amining the living animals, I shall at present forbear from giving 
any account of them. 
** Antenne articulis valde elongatis. 
Spec. 4. Geophilus longicornis. 
G. corpore flavo, capite ferrugineo, antennis longioribus. 
Long. Corp. 23 unc. | 
Habitat prope Edinburgum et Londinum sub lapidibus. 
Classis III.
