NEW AND RARE BRITISH SPIDERS. 109 



Another interesting discovery, made last May, by my nephew 

 and myself, was of numerous examples of both sexes of a curious 

 Saltidd (or jumping spider) Hyctia Nivoyi (Luc) among grass 

 and water weeds in a large bog on Bloxworth Heath. These 

 examples enabled me to prove that the Salticus promptus (Bl.) (Spid. 

 Dors. p. 560) is not the young of Hyctia Nivoyi, as thought by 

 Mons. Simon, but quite a distinct species. The true Hyctia Nivoyi 

 (Luc) is, therefore, now recorded for the first time as British. Its 

 elongated and flattened form will easily distinguish it from any 

 other yet found in Britain. It has, moreover, the curious faculty 

 of being able to run backwards as quickly as forwards. A jumper 

 in the true sense of the word it certainly is not. The discovery of 

 this spider in abundance at Bloxworth, where, though I have been 

 collecting for so many years, I have never met with it before, is 

 remarkable, and should teach us never to be too confident that we 

 have done all that there is to be done in even our best worked 

 localities, nor to be content to leave a single spot unsearched. This 

 spider is probably very local, and on the exact spot where we found 

 it I had not before worked. I have also received from Folkestone 

 (where they were found by Colonel Le Grice, an energetic recruit 

 in the study of spiders) examples of another very fine and distinct 

 Saltidd Pellenes tripunctatus (Walck.) This is indeed a jumper, 

 not only in name but in fact ; its leaps being from 18 inches to 

 2 feet in extent. It has its abode among rough stones and chalk 

 knobs on the cliffs near the shore, and it is a conspicuous object, 

 loving sunshine, and ourjld to be found along our Lulworth and 

 Purbeck coast. This is its first record as a British spider, though 

 it is not rare in many localities on the Continent. I have also to 

 record as new to Britain Enoplognatlta caricis" (Fickert), found 

 by my nephew at Hyde, near Bloxworth. This is a spider of 

 much interest, its generic characters being of so mixed a kind that 

 it has been placed by different -authors in five or six different 

 recognised genera, and is now, finally I think, placed in a genus 

 formed by an Italian araneologist, Syr. Pietro Pavesi, specially for 

 the reception of this and some others of its congeners. My
