tent, the only one which was lit, that the galeodes assembled. 
We saw less of them afterwards, because we had no longer 
any occasion for light. 
“ The species which ran with most celerity, and which was 
most commonly observed, seems referrible to that which Pallas 
observed to the north of the Caspian Sea, and which he has 
described under the name of Phalangium araneoides . The 
feet are very long, and the whole body is hairy, of an ash- 
colour, a little reddish ; the mandibles are entirely ciliated, 
and armed with strong teeth. 
“ We took a second species, Galeodes Phalangium , which 
less frequently presented itself, and which ran with consider- 
ably less rapidity. Its feet are not nearly half as long. The 
body is hairy, and of the same colour as that of the preceding ; 
but the mandibles are of a ferruginous red. They are less 
denticulated, and on the internal side of the upper piece may 
be remarked an arched, recurved, mobile hook, which is 
wanting in the Galeodes araneoides . 
“ We also saw, in the neighbourhood of our tent, two other 
galeodes, which differ but little one from the other, and which 
probably might be, perhaps, like the two preceding, not two 
species, but the two sexes of a single species. In the one, 
Galeodes melanus , the body is very black, the feet short and 
hairy, and there is an arched, recurved, mobile hook, at the 
internal part of the mandibles. 
“ The other, Galeodes arabs , which is evidently a female, 
has the feet very short, hairy, and the body of a velvety 
black. Its mandibles are denticulated, and without a lateral 
hook.” 
Pallas has made his description of the Phalangium ara- 
neoides from two individuals in the collection of Natural 
History of St. Petersburg, without informing us what country 
they belonged to. He considers the differences which he ob- 
served between these individuals, as merely sexual differences
