SPIDERS OF ST. KILDA 221 



isolated and so far north as the island of St. Kilda would, 

 during several weeks' collecting, have furnished more specially 

 northern forms, and probably some new to science, even out 

 of the few met with ; but out of twenty-five species of 

 Araneidea there is not one which is not recorded at various 

 points quite to the south coast of England, while of the 

 four species of Phalangidea one only is a northern form, and 

 so to a certain extent peculiar. In the subjoined list I have 

 noted the points of interest that have occurred to me in 

 respect to the species recorded. There does not appear, from 

 the notes Mr. Waterston kindly sends me, on locality and 

 habitats, any noteworthy variation in the known and 

 recorded habits of the species met with. The fewness of 

 the arachnidous forms met with by Mr. Waterston may be 

 perhaps accounted for chiefly by the limited time he had 

 to devote specially to this group. 



ARACHNIDA. 



ARANEIDEA 



CLUBIONA HOLOSERICEA, De Geer. Adults of both sexes as well as 

 immature examples. One would judge from the number of 

 specimens that the species is an abundant one in St. Kilda, as 

 it also is in most damp and swampy situations throughout 

 England. The examples are also quite as large as those found 

 in more southern localities. 



PROSTHESIMA PETIVERII, Scop. An adult, and an immature female. 

 The species is abundant in the southern parts of England. 

 Mr. Waterston remarks on the voracity of this spider. 



TEGENARIA DERHAMII, Scop, Adults of both sexes of this common 

 and widely distributed house-spider. 



AMAUROBIUS FENESTRALIS, Stroem. Immature examples of this 

 species, which is abundant in the north of England, but gets 

 scarce southwards. 



PHYLLONETHIS LEPIDA, Walck. A single adult female of this very 

 small species, which had lost all but one leg. The occurrences 

 of this little spider are few and far between in Great Britain, 

 the only records known to me hitherto are from Cumberland, 

 Middlesex, and in marshy spots in Dorsetshire, where it is a 

 fairly common species. 



ROBERTUS (Pedanostethus) LIVIDUS, BL -Both sexes adult of this 

 widely dispersed and abundant spider.
