Mr. R. H. Meade on the British species of Phalangiidae. 399 



very pubescent, and of a bright scarlet colour, but having the 

 head and legs yellow and semitransparent. 



In conclusion, I beg to offer my acknowledgements to all those 

 friends who have kindly collected and forwarded specimens of 

 Phalangiidae for my inspection. My thanks are especially due 

 to Mr. Blackwall, Mr. Francis Walker, and Dr. Sichel of Paris. 

 The last-named gentleman sent me numerous interesting French 

 specimens belonging to the different orders of Arachnida, which 

 have been very useful to me in the determination of British 

 species. 



I propose to arrange the species of Phalangiidae in six genera, 

 adopting the following classification : — 



Class ARACHNIDA. 



Order Phalangidea. 



Family PHALANGiiDiE. 



Genus I. Phalangium, Linn. 



Legs long and thin, the second pair being five or six times 

 the length of the body. Body oblong-oval, convex. Cephalo- 

 thorax studded with tubercles, which are often furnished with 

 short spines. Eye-eminence moderate in size, and surmounted 

 by a double crest formed by tubercles or teeth. Abdomen 

 generally marked by an angular dorsal band. Palpi moderate 

 in length except in the males of some species, the second and 

 third joints often with projecting angles, but not branched.
