List of New and Rare Spiders captured in 1861 ; being a Supple- 

 ment to the Lists in Zool. 6493, 6862, 755:3. By the Rev. 

 O. Pickard-Cambeidge, M.A. 



Thk effect of the cold, wet season of 1860 was very visible in the 

 scanty crop of spiders during the spring of 1861. Though, however, 

 the quantity was short, the quality was good, and the result of the 

 season's work was nearly equal to that of the previous year (1860). 

 By the mouth of September, the summer having been a tolerably 

 genial one, spiders appeared in most places to have regained their 

 ordinary numbers; in fact I hardly ever saw a greater abundance of 

 some of our commoner species than during last autumn ; such, for 

 instance, as Epeira solers, E. inclinala, and Linyphia montana, whose 

 webs on a dewy September or October moi-niug show so conspicuously 

 among the heath and furze. The following list comprises, among 

 other rare spiders, ten species discovered or ascertained, during the 

 past season, as new to Science ; seven species recorded for the first 

 time as inhabitants of Great Britain ; three others of which only one 

 sex had been previously discovered ; and nineteen species known to 

 me as British, but which until this last season I had never met with 

 myself. 



Family Salticid.e. 



*Salticus floricola, Koch. I met with this pretty little Salticus in 

 tolerable numbers on dry sandy patches on Bloxworlh Heath, about 

 the middle of May, 1861 : both sexes were adult. Previously only 

 two specimens had been captured in England, and those were taken 

 on the sand-hills at Soulhport, Lancashire, in 1859. The activity of 

 this little spider surpassed everything I have yet observed. Although 

 in length it does not exceed one-tenth of an inch, many of its leaps 

 were more than eight inches in extent. 



*S. nidicolens, Walck. Not infrequent in the same places as 

 S. floricola. 



*S. quinque-partitus, Walck. Of this rare Salticus I captured two 

 adult males in the same locality as the two last. 



S. fasciatus, Walck. I received an adult female of this very dis- 

 tinct and well-marked Salticus (now recorded for the first time as 

 British) from Mr. William Farren, of Cambridge, who captured it on 

 a gate near Brockenhurst, in the New Forest, in June, 1861. I am 

 also indebted to Mr. Farren for several other rare spiders captured in 

 the same locality.
