An adult male of this species, which was first recorded as 

 British by Dr. Leach (see the Supplement to the 4th, 5th, and 

 6th editions of the l Encyclopaedia Britanniea/ article Annulosa), 

 has been transmitted to me by the Rev. Hamlet Clark. An 

 examination of this specimen, which was found near Northampton 

 in the autumn of 1853, and had recently changed its integument, 

 has served to convince me that M. Koch has assigned to this 

 spider its appropriate situation in a systematic arrangement of 

 the Araneidea by transferring it from the genus Clubiona to that 

 of Drassus, as by the figure and disposition of its eyes and the 

 structure of its oral apparatus it evidently appertains to the 

 latter genus. 



After Drassus nitens in the catalogue (Annals and Mag. of 

 Nat. Hist. Second Series, vol.viii. p. 42) add 



Drassus propinquus. 



Drassus propinquus, Blackw. Annals and Mag. of Nat. Hist. Second 

 Series, vol. xiii. p. 175. 



Two adult males of Drassus propinquus, which is closely allied 

 to Drassus nitens, were captured in the spring of 1853; one 

 running on a public road near Llanrwst, and the other in a 

 window of the sitting-room at Oakland. In the summer of the 

 same year Mr. U. II. Meade took an adult male of this species 

 in Norfolk.

After Clubiona comta in the catalogue (Annals and Mag. of 

 Nat. Hist. Second Series, vol. viii. p. 44) add 



Clubiona pallens. 



Clubiona pall ens, Koch, Die Arachn. B. vi. p. 19. tab. 185. fig. 443, 

 444. 



Three adult females and an adult male of Clubiona pallens 

 were received in October 1853 from the Rev. Hamlet Clark, 

 who informs me that they were taken at Holme Fen, in Hun- 

 tingdonshire, about the middle of September in the same year. 



I have not included the Clubiona pallens of M. Hahn (Die
