Conditions here in the first five grades ("none" to "medium") 

 are the reverse of those in all the preceding series, but the "above 

 medium " and " fossa-groove " hold true to the general tendencies. 

 Differences such as these are, however, probably due less to race than 

 to localized group peculiarities.
