extremity is obtuse and slightly enlarged. The digital joint is 

 long, the fore extremity being much elongated or drawn out, 

 though less so than in Tegenaria Ouyonii. The palpal organs are 

 complex, but want the long, curved, slender spine so observable 

 in the last montioned species. 



Found abundantly in cellars, dark unused rooms, and cup- 

 boards at Weymouth, as well as beneath large pieces of detached 

 rock near Pennsjdvania Castle, Portland, where they spin their 

 snares in the hollows and interstices formed by numerous blocks 

 of stone thrown loosely together. Mv. Dale has also sent it to 

 me from Glanvilles Wootton. 



It appears to be rather a local spider, but is found in various 

 other parts of England, though not abundantly. I have also 

 received it from Glasgow. 



TEGENARIA DERHAMII. 



Abanea derhamii, Scopoli, Ent. Cam, p. 400. 

 Tegenabia civilis, Blackw., Spid. Great Brit, and Irel., p. 166, 

 pi. xii., fig. 107. 

 This species is much smaller than Tegenaria atrica, the male 

 being only from 3 to 4 lines in length, and the female 5 to 

 5& ; it is also far more abundant, and more generally distributed, 

 being in fact the common house-spider of Europe. It 

 also extends its habitation to North America, New Zealand, 

 Africa, St. Helena, and other exotic regions ; to some, or all, of 

 which placos it has most probably been introduced in merchant 

 vessels, among goods and packages. It is of a dull whitey- 

 brown, or yellow-brown, colour on the abdomen, marked along 

 the middle with a series of somewhat triangular, dark-brown, or 

 sooty-black spots or patches, on each side of which are some 

 rounder ones, also disposed longitudinally ; these are sometimes 

 united, and, with other spots and markings of a similar colour 

 form the abdominal pattern. The cephalo-thorax is reddish 

 yellow-brown, with blackish margins and lateral longitudinal 

 bands ; and the legs are also of the same colour, the metatarsi
