BRITISH SPECIES OF FALSE-SCORPIONS. 213 



Cephalothorax very glossy, bright, dark yellowish-brown, often 

 slightly tinged with reddish ; falces and palpi with a stronger red 

 tinge. Abdomen dark yellow-brown ; legs pale brownish-yellow. 



Gaput rather roundly truncated in front ; cephalothorax a little 

 but distinctly longer than broad, sides parallel; eyes on slight 

 tubercles and tolerably large, the anterior eye on each side is 

 separated from the fore margin of the caput by at least half a 

 diameter, sometimes to nearly a diameter's interval, and a similarly 

 varying interval separates the anterior and posterior eyes from 

 each other. The anterior eye is round, the posterior slightly larger, 

 and of rather an irregular form. The palpi are long, the pincers 

 long and strong ; the claws are considerably (sometimes at least one 

 half) longer than the bulb, and curved; they also form a distinct 

 though obtuse angle with the bulb ; the humeral joint is distinctly, 

 though not strongly, granulose, both before and behind. The 

 falces are less in length than the cephalothorax. 



This is an abundant species at Bloxworth and its neighbourhood, 

 among moss and dead leaves in woods, at all seasons of the year, 

 and I have met with it in many other parts of Dorsetshire. It is 

 also widely distributed in Great Britain. It has been sent to me 

 by, among others, Mr. J. B Masefield, from Staffordshire ; by the 

 Rev. F. 0. P. Cambridge, from Cumberland ; by Mr. J. C. Bignell, 

 from Devonshire ; by Mr. Reid, from Epping Forest, where I also 

 found it myself ; by Mr. E. A. Butler, from Hastings ; and by Mr. 

 "W. F. Blandford, from Dartmoor. Mr. J. H. Carpenter has also 

 sent it to me from Ireland. 



In respect to the number of joints in the two first pairs of legs, 

 M. Simon states, p. 7, that in no case has he found a joint between 

 the femur and tibia in false scorpions ; but in some examples of 0. 

 muscorum I have undoubtedly found (a), the coxa ; (6), the 

 trochanter or exinguinal joint; (c), the femur (undivided) ; (d), a 

 short joint ; (e\ a longer one ; (/, g), tarsus, distinctly sub-divided 

 into two joints (vide plate 1, fig. 3). (d) Appears distinctly to 

 serve as a genual joint, while (e) is the real tibia. A type of 

 muscorum (Sim.) has also similar joints to those above described.
