X. On new and rare British Spiders (being a Second Supplement to “ British Spiders 
| new to science," Linn. Trans. vol. xxvii. p. 393). By the Rev. O. P. CAMBRIDGE, 
M.A., C.M.Z.S. Communicated by H. T. STAINTON, Esq., Sec. L.S. 
(Plate XLVI.) 
Read December 5th, 1872. 
IN the first Supplement (lately published, Linn. Trans. xxviii. p. 433) to the com- 
munication referred to above, our knowledge of British Spiders was brought down to the 
end of the year 1870; in this second Supplement are included many new and rare species 
discovered since that time, together with a description of a new European Cheiracanthium 
(whose precise locality, however, is unknown). Several rectifications of synonymy are 
also comprised in the present paper, which thus brings down the discoveries in this 
branch of science (relating to British Araneology at least) to the present time. 
The figures contained in the plate which illustrates this paper have been taken from 
the author's own sketches; and it is hoped that, though rough, they may be of use in 
the identification of the species to which they refer. The arrangement adopted in the 
present paper is (like that of the two former ones) that of Mr. Blackwall in * Spiders 
of Great Britain and Ireland.”

The interchange of Swedish and English examples of both sexes of the spiders 
described under the above names proves conclusively that they are of one species. It 
has also lately been discovered in Wales by Mr. Blackwall.

The examination of adult females of L. piscatoria (Clerck) received from Sweden from 
Dr. Thorell leaves no doubt in my mind that the adult male described by myself
