BRITISH SPECIES OF FALSE-SCORPIONS. 215 



shorter then the humeral, and its stem is straight, distinct, and the 

 bulb on this portion of its inner side springs rather abruptly from 

 it, thus differing also from 0. muscorum (Sim.) The humeral 

 joint is devoid of granulations. The hairs, such as still remained 

 uninjured, are fine and simple. In regard to the joints of the 

 first two pairs of legs, this species resembles 0. muscorum (Leach) 

 in other general respects also there is much similarity. In the 

 prepared specimen the colour appeared to be dull yellow-brown, 

 with paler legs. 



OBISIUM MARITIMUM. PL B, fig. 8. 



Syn : Obisium maritimum, Leach. Zool. Misc. iii., p. 52, 

 pi. 141, f. 1, 1817. 



Length slightly over 1 line. 



Cephalothorax and abdomen dark brown tinged with olive, and 

 very glossy ; palpi and falces red-brown ; legs pale yellow-brownish 

 tinged with olive. Cephalothorax slightly longer than broad, sides 

 parallel, truncated in front in an oblique line on either side from 

 the centre, where there is a slight but distinct shallow depression. 



Eyes rather large, very nearly of equal size ; those of each pair 

 are separated from the fore-margin and from each other by a 

 diameter's interval. The hairs with which this species is furnished 

 are long, fine, and simple. The palpi are long and strong ; the 

 bulb of the pincers is of a cylindrical-oval form ; the claws are 

 strong and no more than (if even quite as much as) equal to the 

 bulb in length, and very slightly curved. 



I have received this very distinct species (which does not appear 

 to be known on the Continent of Europe) from the Devonshire 

 Coast, where it was found and kindly sent to me by Mr. G. C. 

 Bignell, of Stonehouse, Plymouth. Its habitat was, Mr. Bignell 

 informs me, under stones below high water mark. I have also 

 received it from a similar situation in Jersey from Mr. J. Sinel. 



M. Simon conjectures (Arachn. de France, torn. 7, p. 67) that 

 the Obisium maritimum of Leach is probably identical with either 

 0. (Roncus) lubricus L. K. or R. Cambridgii L. K. But Leach
