SrtDEKS OF OUEIINSEY. 373 



Island, 1. The author remarks that "the large total placed to 

 the credit of Sark is undoubtedly due to the zeal displayed by 

 the late Mrs. Collings in collecting material ; for she alone, 

 save for a few collected by Mr. Walker, has worked among 

 the spiders of that island." Among all the species recorded 

 only one, Heliophanus Camhridgii^ is not British. 



Two further contributions by the same able arachnologist, 

 printed in our Transactions for 1899 and 1902, furnish 

 additional information about the spiders of Alderney, based on 

 collections made by me during my residence there, and raising 

 the number of species for that island to sixty-nine. 



The list which I have to-day the pleasure of submitting 

 to you considerably increases the record both for Guernsey in 

 particular, and for the whole of the Channel Islands as a 

 group. It comprises the result of about fifteen months' 

 assiduous and iminterrupted collecting, during Avhich I have 

 searched all parts of this island, and every kind of situation, I 

 think, in which spiders are likely to be found. The list may 

 therefore be regarded as a fairly good enumeration of the 

 spider-fauna of Guernsey. The want of woods and copses in 

 this island, as well as the absence of limestone, no doubt 

 accounts for the lack of a number of species which are more or 

 less commonly distributed throughout the southern counties of 

 England ; but on the whole the list is, for so small and 

 circumscribed an area as Guernsey, a very fine one ; and the 

 number of non-British species, as also of species which are 

 rare in Britain, adds to its interest. 



As to the accuracy of the names, it is only needful for me 

 to state that every species has been identified by the Rev. 

 O. Pickard-Cambridge, F.R.S., who has for a great many 

 years been recognised as the highest authority in our own 

 country, if not in Europe, on this order of the Arachnida. I 

 am under deep obligation to Mr. Pickard-Cambridge for 

 his kindness in examining the large consignments of spiders 

 which I have forwarded to him every few weeks in the 

 course of my collecting, and for the trouble he has taken, 

 necessarily at the cost of much time and labour, to make out 

 for me detailed lists showing the number of specimens of 

 each species forwarded in each consignment. These figures 

 show that I have submitted to him between 11,000 and 12,000 

 specimens, all of them taken in Guernsey, so that from these 

 returns it is possible to form a pretty accurate estimate 

 of the comparative rarity or frequency of each species in this 

 island, at any rate during the period over which rnj' researches 

 have extended. Mv own share of the work has been confined
