Norr.—The number of cusps on the abdomen is not constant. Of W. tauricornis there are two varieties : 
(1) the type, which has the shoulder-cusp bifid and three lateral cusps present ; (2) a form with the shoulder- 
cusp simple and two lateral cusps only present. .

This spider closely resembles W. 11-tuberculata, and may possibly prove to be a 
variety of that species. The specific difference lies in the form of the clavis of the 
palpal bulb, which can be best recognized by reference to the Plate and figure. 
‘Trochanter iv. has a single spine.
