Lycosa pullata (Clk.) 1757. 



This species was less common than might have been ex- 

 pected. The specimens exhibited a good deal of individual vari- 

 ation, especially in the female sex. It is interesting to note that 

 very few of the examples appeared to approach L. prativaga 

 in any way. Seeing how weakly defined many of the species 

 of Lycosa appear to be, and how the specific barriers between 

 them are in constant danger of being broken down it is rather 

 sursprising that forms intermediate between L. prativaga and 

 L, pullata are not frequently met with. 



Lycosa riparia G. L. K. 1848. 



This fine and unmistakeable species occurred very rarely 

 in the collections. 



Lycosa nigriceps Th. 



Occurred in two collections only. It seems to be far more 

 common in Central Europe than in the extreme north. The 

 specimens were quite typical. 



Lycosa luguhris (Walck.) 1802. 



This species was exceedingly abundant in a large proportion 

 of the collections. The females exhibited very considerable vari- 

 ation in form, especially in the epigynum. 



Lycosa amentata (Glk.) 1757. 



The commonest species. Both sexes varied considerably in 

 size and markings; and the epigynum of the female in many 

 cases was so far removed from the typical form that, had 

 there not been long series available to assist one in the matter 

 of determination, one would quite possibly have created new 

 species for some of the more aberrant forms.
