these as follows : (1) A small-sized breed of the bulldog or 

 pugdog type, characterized by a short snout, with undershot 

 jaw ; (2) a small house-dog like a Dachshund, with slender 

 snout ; and (3) a larger slender-limbed dog, with wolf -like 

 skull, originally described by Tschudi under the name Canis 

 ingw peeuaritis. According to Dr. Nehring, the two smaller 

 breeds were derived from the larger wolf-like variety, which, 

 he states, was itself derived from the American wolf. The 

 presence of a tibia of a large wolf-like dog among the bones 

 collected at Cuzco, while it offers no proof of great antiquity, 

 certainly does not in any way render such a view untenable. 



Bos sp. 



10. The metatarsus, or " cannon bone," of the left hind leg. 

 The length of the bone without the distal epiphysis, which was 

 not preserved, is 19*0 cm , or 7J inches. Subsequent to the loss 

 of the epiphysis, and prior to deposition in the locality where 

 found, the bone has been eroded to such an extent that the 

 sharp edges of its modelling are destroyed. 



11. A small fragment of a right radius. 



12. A fragment of a 1st right thoracic rib. 



Realizing the importance of determining whether these 

 bovine remains belong to a feral or to a domestic race, I have 

 endeavored to obtain all possible evidence on this difficult 

 question. As j;hese fragmentary bones (10, 11, and 12) are 

 among the least characteristic parts of the skeleton, their exact 

 specific identification is beset with almost insuperable difficul- 

 ties. While it is a simple matter to distinguish the hind 

 cannon bone of a slender-limbed dairy cow from that of an 

 adult Bison, a careful study of a large series of specimens 

 shows that metatarsi of an intermediate type exist, which 

 baffle specific identification unless accompanied by other more 

 characteristic skeletal parts. This is true of the cannon bone 

 designated as bone 10. The fact that the epiphysis is missing 

 warrants the supposition that the bone is from a young animal, 

 and accordingly had not attained its full growth. The frag- 

 ment of a radius (bone 11) is too meager to be of any assistance 

 in the present search for specific characters. The bovine 

 specimen that is of greatest interest is the fragment of a 1st 

 rib, designated as bone 12. I have examined the 1st ribs of 

 the following Bison, Bos americamis : An adult male and an 

 adult female in the Yale University Museum ; an adult male 

 and a young female in the U. S. National Museum ; and an 

 adult male and a young female in the Museum of the Brooklyn 

 Institute of Arts and Sciences. In all these, the origin of the 

 external intercostal muscle is marked anteriorly by a well-
