THE GENUS TAPINOCYBA. 255 



Post-ocular sulci not straight. Beginning behind the 

 posterior lateral eyes, they curve sharply inwards. They 

 reach a point about one diameter behind and external to the 

 central posterior eyes, and then run backwards and a little 

 outwards. Finally in their posterior thirds, or halves, they 

 become straight. They vary considerably in a long series of 

 specimens, and frequently, as in M. Simon's specimen, the 

 curves are badly marked. These curves are, however, in my 

 experience always present. 



Palpi. Patella much shorter than tibia. The apophysis of 

 the latter springs from the whole of the dorsum of the anterior 

 border, and is nearly or quite as long as the joint itself. It 

 terminates in a single fine sharp point. In M. Simon's spider, 

 described as a separate species, the tibial apophysis is a little 

 shorter than usual, but not more so than occurs in other 

 specimens that I have examined. Tarsus small and narrow. 

 Palpal organs small and inconspicuous. 



Female. — Length i*6 or 17 mm., or more. There is more 

 disparity in sizes between the sexes than in the other species 

 of the genus Tapinocyba. 



Cephalothorax rounded, without elevations or sulci. 



Eyes. Posterior row practically straight. The procurvature 

 is exceedingly slight. Eyes about equidistant. 



Vulva. Aperture of oviduct very small, inconspicuous, and 

 not much broader than long. Spermotheca placed on each 

 side of it. 



Abdonien, when distended with ova becomes very large and 

 almost globular. For this reason the female is often much 

 larger than the male. 



Legs in both sexes are rather longer than obtains in the 

 other species of the genus. 



Distribution. — England : Dorset, London, Lancashire, 

 Yorkshire, Cumberland, and Northumberland. Scotland : 

 Near Edinburgh. Also in France and Switzerland. The 

 specimens recorded by Bosenberg, from Germany, probably 

 are not referable to this species.
