When I wrote from Clerck's original specimen, which was 

 shrunken and injured hy time, the above cited description of Theri- 

 dium cellulanum (which has been repeated by Westring), I possessed 

 no further knowledge of the spider described by Walckenaer under 

 the name of Lin. crypticolens, and by C. Koch as Meta cellulana 

 (Clerck), and accordingly did not venture to take up these names 

 as synonyms of Clerck's Ar. cellulanus. Since that time I have in 

 company with Dr. L. Kocu taken numerous specimens of this spe- 

 cies at Niirnberg , and have thus been able to convince myself, that 

 C. Koch determined his Meta cellulana rightly, and that the syno- 

 nyms above given really belong to the species described by Clerck 

 and me. — Linyphia cellulana Stjnd. (Sv. Spindl. Beskr., in Vet.- 

 Akad. Handl. f. 1831, p. 109) does not belong to this species, but 

 to Lin. bucculentu Clerck: vid. sup. p. 53. — Lin. nebulosa Sund. , 

 which Walckenaer inserts among the synonyms of his Lin. crypti- 

 colens (Ins. Apt., II, p. 278), is an entirely different species, and 

 identical with that, which Westring denominated Lin. crypticola (see 

 that species above, p. 54). Similarly C. Koch has erroneously ad- 

 mitted Lin. thoracica Keuss, on which vid. supr., p. 52, among the 

 synonyms of his Meta cellulana. 



Mr. G. Eisen has kindly given me a fullgrown male of Nesticus 

 celluhmus taken by him at Lugnas in Westergotland : this is, as far 

 as I know, the only instance of its having been met with in Sweden 

 since Clerck's time.
