For purposes of comparison of these three races a table of 

 extremes and averages has been prepared for certain of the 

 features which show a significant degree of subspecific con- 

 stancy.

Fasciata, it will be seen, is strictly intermediate between co)i- 

 fluois and pictiventris, except that in proportional tail length 

 it is much closer to pictiventris. In general appearance also 

 these two are much more like each other than either is like 

 confluens.
