Harinoso de Ocho. First becoming evident in Level 2 
of Swallow Cave, there has come into the evolutionary 
picture an eight-rowed large-seeded corn, similar to 
Harinoso de Ocho (illustrated in Plate X LVI), which is 
still occasionally found in western Mexico in the states 
of Sinaloa and Sonora. Wellhausen et al (1952) described 
this race and postulated that it was introduced into Mex- 
ico from South America in pre-Columbian times. It has 
subsequently been found in Colombia, where it is known 
as “‘Cabuya’’ (Roberts et al, 1955). This race also shows 
some resemblance to the prehistoric flour corn of Cafion 
del Muerto, described by Anderson and Blanchard (1942), 
and it probably has affinities with the eight-rowed flour 
corn of the Northern Plains Indians, especially the Man- 
dan. Specimens of archaeological cobs of this type of 
corn are illustrated in Plate XLII and a single kernel 
from Dark Cave is illustrated in Plate XLIV, Fig. A. 
Cristalino de Chihuahua. The fifth type of corn in 
Swallow Cave is (with the exception of two cobs in Level 
3, which may be intrusions) found only in Levels 1 and 
2. The cob of this maize is larger than that of any of the 
preceding types, is more or less cylindrical in shape, and 
represents an excellent blending of the characteristics of 
the three preceding entities: Chapalote, Tripsacoid 
maize, and Harinoso de Ocho. The cobs of this maize 
have their counterparts in a modern race collected in 
Chihuahua and described by Wellhausen e¢ al under the 
name Cristalino de Chihuahua (Plate XLVII). The 
archaeological cobs are shorter than typical cobs of the 
modern race, but in other respects they are quite similar. 
Furthermore, the kernels from several of the caves re- 
semble the kernels of the modern race, in being thick, 
flinty, sometimes slightly dented, and predominantly 
white. This type of corn has affinities with the modern
