 occurred at Glanvilles Wootton, and has been met with in various 

 other parts of England and Wales. 



GENUS TEOCHOSA, C. L. Koch., Thorell. LYCOSA, Bhckw. 

 in part. 



In this group the eyes, although unequal in size, do not 

 usually differ as much as in the succoediug genera — Tarentula 

 and Lycosa — nor is the area occupied by them, usually so large 

 in comparison with the broadth of the caput. Tho length of the 

 anterior row either exceeds perceptibly, or is never less than 

 that of the second (or middle) row ; and its two central 

 eyes are larger than the laterals. {Trochosa leopardus is, however, 

 an exception in respect to this last character). As in Pirata, the 

 anterior row of eyes is very close to the lower margin of tho 

 clypeus ; the interval not much exceeding, in any case, the 

 diameter of one of its central eyes. 



The sides of the caput (looked at from in front) are sloping 

 but convex, and the "Facies" is low. 



The legs are moderately long, strong, and not much attenuated 

 at their extremities. 



The spidors of this genus conceal themselves under stones, or 

 low down among herbage in damp places ; some form cylindrical 

 holes in the earth, bning them with silk. One (T. picta) may 

 be found at times running in sandy or gravelly places in sun- 

 shine. 



Six species have been recorded as British ; and of these four 

 are found in Dorsetshire. 



All the spiders included in Trochosa are joined by M. Simon 

 with Tarentula, to form his genus Lycosa. I am unable, how- 

 ever, at present, to enter fully into this new arrangement, con- 

 fessing at the same time that the generic divisions adopted here 

 are not as strongly and satisfactorily marked as could be desired.
