ters, but is rather larger and wants the elevation of the caput. 

 Found onoe on a wall, as well as more frequently, sovoral years 

 afterwards, during the spring months, among moss and dead 

 leaves in woods, at Blox worth. 



WALCKENAERA IMTLANA. 



"Walokenaera implana, Cambr., Trans. Linn. Soc. xxvii., p. 

 456, pi. 57, No. 41. 



The adult male of this small species measures 1-1 7th of an 

 inch in length. The caput is considerably elevated, but not so 

 roundly and obtusely as that of Walckenaeralatifrons, Cambr., and 

 the anterior slope of the elevation is more nearly vertical ; the 

 lower part of the clypeus is considerably and roundly prominent. 

 The eyes are in the ordinary position, but, when looked at from 

 in front, that of the fore-central pair is above the straight line 

 of the two lateral pairs ; behind each of these last is a longi- 

 tudinal indentation. 



The colour of the cephalo-thorax is dark black-brown, that of 

 the legs and palpi pale yellow, and of the abdomen glossy black. 



The radial joint of the palpus is shorter than the cubital, and 

 has its fore extremity, on the upper side, produced into a long 

 narrowish apophysis directed obliquely outwards, imperfectly 

 bifid at its extremity, and with a sharp-pointed, black, spine- 

 like projection issuing outwards, from beneath, near the bifid 

 part. The palpal organs are prominent and complex, with a 

 conspicuous, duplex, black, coiled spine at their extremity. 



A single example found among low plants in underwood at 

 Bloxworth, in July, 1863. 



WALCKENAERA BECKII. 



"VValokenaera beckii, Camlr., Trans. Linn. Soc. xxvii., p. 460, 

 pi. 57, No. 44, and xxviii., p. 548. 



Length of the adult male 1-1 6th of an inch. 



The caput is but very slightly clovatod ; the elevation is, how- 

 ever, distinct, and its upper surface is broad and flattish, being
