12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. IO3 



Slightly variant examples of the type have been reported from 

 numerous sites, mainly of the Classic and later periods, in the Pueblo 

 area where they generally are considered as "unusual" forms (Cos- 

 grove, 1932, pi. 51, a; Kidder, 1932, fig. 6). They probably bear 

 some relationship to the more highly developed points found in Okla- 

 homa, some of the southern States, and even in parts of Mexico, 

 that are characterized by such deep basal concavities that they appear 

 to have wings. Beyond their late horizon, however, they do not seem 

 to have any special local significance and certainly cannot be regarded 

 as a criterion for the presence of any specific group in the area. All 

 four of these types of points are in association with bones from 

 modern bison, deer or antelope, and jack rabbits. 



The fifth type, found in a buried occupation level in the lower plain 

 (pi. 3, fig. 2), is a rather stubby form with roughly parallel sides, 

 flat base, and sharply tapering tip (fig. 2, d). First thought was that 

 the implement was a drill made from a broken point, but careful 

 reconsideration and study of several examples indicates that it prob- 

 ably was a form of projectile. In a general way it bears resemblance 

 to some of the points from the Edwards Plateau district in Texas 

 and also some of those from the Big Bend region, yet it is sufficiently 

 distinct to be considered as representing a separate class. Possible 

 relationships may be determined by future work in the region. Asso- 

 ciations in this case consisted of modern bison, deer, and bones from 

 small mammals. The type, as previously mentioned, appears to be 

 contemporaneous with the third main group, yet eventually may 

 prove to be somewhat older. 



Projectile points were the only artifacts obtained from the oldest 

 and subsequent Yuma horizons, unless a few nondescript flakes 

 capable of utilization as knives or scrapers be considered as tools, 

 and there is no information regarding other kinds of implements 

 comprising the complexes to which they belonged. Further data 

 along this line are essential to a proper understanding of the subject 

 as a whole. Several kinds of scrapers, knives, choppers, hand ham- 

 mers, and grinding stones were associated with the later type points. 

 In the case of the fourth series there was the addition of potsherds. 



The ubiquitous snub-nosed or end scraper (pi. 4, e-k) is one of 

 the more prevalent forms in the group of scrapers. As is usually the 

 case, most of the examples are of the uniface, planoconvex type with 

 the flat side showing little or no chipping and the curved side having 

 had just enough flakes removed to give the implement its characteristic 

 shape. The convex, broad end and two edges were retouched by the
