the concavity varying in outline on different specimens, and there are 

 frequently long, sharp base points often called " ears." Between the 

 edges of the blade and the lateral ridges produced by the central 

 grooves is a more or less fine marginal retouching, a secondary removal 

 of small flakes. Points in this group tend to be somewhat stubby, as 

 they are broad in proportion to the length. The second form, B, was 

 present in the type site but is rarely mentioned in discussions because 

 of the general lack of information on the subject. It is also a thin,

leaf-shaped blade with characteristic fluting on the faces. In contrast 

 with the first form, however, it is long and slender in outline and has 

 a tapering rather than a rounding tip. The type of base for this 

 second form is not known from Folsom, as the specimens found there 

 were broken, the butt ends being missing. Similar points from the 

 Lindenmeier site have concave bases. Hence it is permissible to 

 assume that the same was true for the specimens from the type site. 

 It is quite possible that some of the broken bases from Folsom were 

 from B form blades, although there is nothing to substantiate that 

 assumption.
