BRITISH SPECIES OP FALSE-SCORPIONS. 221 



buildings at Peckham, another in an old account book in 

 London, and the fourth in an old building at Westminster. These 

 all agree well with typical European examples received from M. 

 Simon, and, after a careful examination of the type of Acarus 

 cancroides in the Linnean Society's cabinet, I believe them to be 

 the same as the species described by Linnaeus. The drawing from 

 which the figures of this species were engraved was made for me 

 by Miss Fisher, of Fulham-road, London, from one of the Peckham 

 specimens in the British Museum. 



CHELIFER MERIDIANUS. PI. C, fig. 15. 



Syn : Chelifer meridianus, L. Koch. Darst. Eur. Chernet., p. 

 20 (1873), and Simon, Arachn. de France, torn. 7, p. 25 (1879). 



Length rather over 1 line. 



Ceplialotlwrax dark yellowish-brown, its surface thickly 

 shagreened, and granulose on the margins. Palpi tinged with 

 reddish, surface shagreened, in some parts granulose. Abdominal 

 plates shagreened and dark yellow-brown. Legs pale yellow-brown. 

 The hairs on the cephalothorax, palpi, and abdomen are short, pale, 

 and all clavate. 



The caput is broader (from front to back) than the thorax, of 

 which last the hinder portion is less than half its breadth. 



The eyes are large, but indistinct, and about half a diameter's 

 distance from the fore margin of the caput. 



The palpi are rather short, strong ; the axillary joint is strongly 

 and roundly protuberant on the upper side, as well as underneath 

 on the posterior side. The humeral is longer than the cubital 

 joint, and the cubital is strongly protuberant on the inner side 

 towards the hinder extremity. The bulb of the pincers is of the 

 same length as the cubital joint, and the claws, which are slightly 

 curved, are equal to the bulb in length ; this last is short, stout, 

 and broadest near the hinder extremity. The shorter, stronger 

 palpi, and their clavate hairs, as well as the equal length of the 

 claws and bulb of the pincers, will serve to distinguish this species 

 at a glance from C. subruber.
