Arachnida. 6803 



when in company with Mr. Meade, in a wood near Bradford, among 

 moss and decayed leaves, in May, 1859. 



Family Thomisid^. 



Thomisus claveatus ( Walck). A specimen of this very peculiar and 

 distinctly marked Thomisus was found by myself near Pennsylvania 

 Castle, Portland, in September, 1858, but it was unfortunately lost 

 before its species was ascertained. This last October (1859), how- 

 ever, I have succeeded in capturing, on the same ground under stones 

 and pieces of rock, several adult specimens. Walcknaer speaks of it 

 as a very rare spider on the Pyrenees and in Egypt ; its rarity 

 he accounts for, from its sparing fertility, its egg-sac only containing 

 five or six eggs at a time. It is the most sluggish, inactive species 

 that 1 have met with, of even this generally very inactive genus. 



T. audax. Three specimens of this species were captured ou 

 the sand hills, Southport, in May, 1859. 



Family Deassid.e. 



Drassus purailus. Adult males and females of this well-defined 

 species were discovered by myself on the north sand hills, Southport, 

 during the summer of 1859. They were found both running on the 

 bare sand, and also lurking at the roots of moss and grass : it seems, 

 however, to be a rare species, and has not hitherto been recorded as 

 British, It has a remarkable facility of burying itself in the loose 

 sand at the approach of danger; several of those I captured were out 

 of sight in a minute. 



D. clavator. An adult male of this species (new to Science) was dis- 

 covered by myself on the north sand hills, Southport, in April, 1859, 

 by raking with a stick under the rooty ledges of the sand hills. I 

 captured also an immature female under a stone on Kirkby Moss, near 

 Liverpool, June 14th, 1859 ; and in October of the same year, I found 

 it in abundance, under stones and pieces of rock, close to Pennsyl- 

 vania Castle, Portland. It is a fierce, active spider, and, among the 

 rocks, very difficult to capture. A description of this species, to 

 which I have given the name " clavator," fiora the very large club- 

 shaped digital joint of the palpi, will appear shortly in the ' Annals 

 and Magazine of Natural History.' 



D. lapidicolens (Clubiona lapidicolens, Walck.). An adult male 

 was captured at Freshwater, Isle of Wight, in May, 1859, by 

 my friend Frederick Bond, who kindly forwarded it to me, together 

 with specimens of the new Ciniflo (C. mordax) discovered there by
