general appearance very much resembles both the first and 

 the last. 



The palpal organs present some decided differences ; the 

 point, e, is not so sharp or prominent ; the falciform process, 

 a, is broader and more circularly curved ; the spines at the 

 apex of the organs are not the same. (^See PI. II. fig. 1 a.) 



The epigynal orifice is, as far as I am able to ascertain, 

 almost always transverse-oval, never quadrate, as is that of 

 Meadii. 



The central anteriors are not so small in proportion, while 

 the spine, mentioned above on the penultimate joint of all 

 four pairs of legs, will prevent any confusion. 



The pale broken transverse lines on the pale olive abdomen 

 will prove a really reliable character. 



Iljiwards of 250 of the female sex were received from 

 jMr. Campbell, but no males. A single male was found 

 amongst the Dorset specimens ; while both males and females 

 were received from Dr. Meade, in addition to the four 

 original types, females, from Mr. Blackwall's collection. 



All these specimens seem to have been taken either running 

 upon railings or amongst grass in March and April ; and a 

 very interesting account of them is given by Mr. Campbell 

 in ' Trans. Hert. Nat. Hist. Soc' 1883, vol. ii. pt. 7.

Length of male 1 line ; female H line. 



CeplialoOwrax oval-elongate; caput bluffly rounded, bearing 

 a longitudinal row of curved hairs. 



Eyes fairly large : posterior row straight, centrals one 

 diameter apart, two diameters (or almost) from laterals ; 

 anterior row straight, centrals smaller, half a diameter apart, 

 two diameters (or almost) from the laterals. Clypeus as high 

 as ocular area, vertical, set with short hairs. 



Legs fairly long : femora i. with one spine on inner side 

 and one spine on upperside, towards apex ; ii. with one spine 

 about the middle ; iii. and iv. without spines. Femora 

 clothed beneath with a double row of long setiform hairs, the 

 pair at the apex being longest and stoutest. Genual joints 

 with a long (three times diameter of joint) oblique spine at 

 the apex. 



Tihicb i. with three long spines at apex (one dorsal, two
