tent, the only one wliicli 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 Phalangiiim 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
