lower margin of the chelicerae is armed with two rather than three 
teeth.” Gertsch (1934) listed L. orophila as a junior synonym of L. 
pratensis and reported upon the geographic distribution of the 
number of teeth on the lower cheliceral margin. Chamberlin and 
Ivie (1947) later compromised by relegating orophila to subspecies 
status, presumably because of the difference in number of teeth on 
the posterior cheliceral margin. The geograpic distribution of the 
character in over 1300 specimens is shown by Map 1 and Table 1. 
Since a single symbol on the Map 1 may indicate from one to 50 
specimens a more accurate distribution of actual numbers is given 
by province and state in Table 1. From these data it is clear that 
subspecies of T. terricola in North America cannot be delineated by 
the number of posterior cheliceral teeth present in certain popula¬ 
tions. Measurements of selected specimens from the eastern and 
western United States indicate a slightly larger average size for those 
in the East. However, there is considerable overlap in size and none 
of the other anatomical characters measured allows separation of 
these populations into subspecies (compare Measurements of east¬ 
ern and western populations). It is possible that biochemical, eco¬ 
logical or behavioral studies may help clarify the relationships of the 
populations of T. terricola in Europe and the eastern and western 
United States. Until more information is forthcoming, I find it diffi¬ 
cult to recognize subspecies of T.. terricola.
