the custody of his collection of British spiders) has assisted me with 

 the utmost kindness and liberality both in word and deed, still the 

 number of British spiders, especially of the genera Linyphia, Neriene 

 and Walckenaera, which I have not myself seen, is very considerable ; 

 of many indeed the types are no more in existence ')• 



Most of Blackwall's species have been also described by We- 

 string, and for these I need only refer to the corresponding articles 

 in the foregoing pages. A great number of the rest are to me un- 

 known, and of these — which I have marked with an * — I have in 

 most instances little or nothing to say. It is therefore for a part only 

 of the species described by Blackwall and not taken up in We- 

 string's work, that I am here going to account in the same manner 

 as I have done for the last-mentioned author's species; but I shall 

 afterwards give a complete list of the spiders described in the 'Hist, of 

 the Spid. of Gr. Britain and Ireland', together with a statement of the 

 name which I believe ought to belong to each of them, the year 

 in which the assumed specific name was published, and the work 

 in which this publication took place, or, instead of these last-men- 

 tioned particulars, a reference to the place in the present work, where 

 the species may have been more fully treated of.

 Blackwall's great work.
