DYSDERA CAMBRIDGII, 

 Dysdera cambridgii, Thorell, Syn. Eur. Spid., p. 455. 

 Dysdera erythrina, Blacho., Spid. Great Brit, and Irel., 

 p. 370, pi. xviii, fig. 266. 

 This spider is found, but rarely, in old buildings, among damp 

 moss, and at the roots of heather at Bloxworth, but is very abundant 

 near Pennsylvania Castle, Portland, under stones and detached 

 pieces of rock; in such situations, as well as in cracks and 

 crevices of the earth, it dwells, and spins a thin silken tube. 

 The length of the female is very nearly or quite half an inch, 

 while the male is rather smaller. Legs, 1.4.2.3. 



DYSDERA CROCOTA. 



Dysdera crocota, C. Koch, Die Arachn. V., p. 81, pi. 166, 

 fig. 392-394.

 pi. xviii., fig. 268. 

 Vory nearly allied to B. Camlridgii, which it resembles closely 

 in colours, but is usually rather larger ; the falces of the male 

 are stronger, and the form of the palpal organs is different ; in 

 the present species they terminate with a prominence on either 

 side, forming an obliquely-transverse portion, which is entirely 

 wanting in B. Cambridgii ; the basal portion is also of a much 

 more globular form. 



Found occasionally in the Island of Portland under stones ; 

 and once in an old building at Bloxworth. 



GENUS HAEPACTES, Templeton. DYSDEEA, Bl. (in part). 



Harpades is very nearly allied to Bysdera, but may be dis- 

 tinguished by a more pointed caput, and three, instead of two, 

 terminal tarsal claws ; the oyes also form nearly an unbroken 

 circle, owing to the noar proximity to each other, of the two 

 foremost ones. One species only is known in Britain, and that 

 one is frequont in Dorsetshire. Logs, 1.4.2,3.
