The average of the measurements in this series shows 

 that the Dingo, as a breed, has a basi-condylar length of 

 177*3 mm. and an upper carnassial length of 20 mm. 



Table II. shows corresponding measurements of a series 

 of domestic dog skulls, some of the figures being taken from 

 the published records, and some from specimens in the South 

 Australian Museum : —

It will be noticed from these tables that the Dingo, 

 as a type, is a dog which possesses very large teeth, for the 

 small-headed Dingo may have a condylo-basal length of only 

 165 mm. (No. 2, Table I.), and yet possess an upper car- 

 nassial tooth as large as that of a St. Bernard, the condylo- 

 basal length of whose skull is as great as 248 mm. (No. 2, 

 Table II.). It may be mentioned that the two greyhound 

 skulls, in the South Australian Museum series, were mixed 

 in with the 20 Dingo skulls, and although their measurements 

 do not appear strikingly different from those of the Dingos, 

 nevertheless, their relatively small teeth enabled them to be 

 picked out with certainty before any measurements were 

 taken. Of the very small series of dog skulls which I have 

 been able to examine the Chow dog shows the greatest like- 

 ness to the Dingo in the form and proportions of the upper
