HEREDITY AND ORGANIC SYMMETRY IX ARMADILLO. ~ 



After many experiments in tabulating the occurrence of band 

 and scute anomalies I have adopted a simple pictorial scheme 

 which will readily explain itself on examination of the diagram- 

 matic Figs. 2, 4 and 7 which are simplified representations of the 

 scute conditions shown in Figs, i, 3 and 5 respectively. The 

 numbers of scutes in both double and single regions are repre- 

 sented by arabic numerals and the number of the band is indi- 

 cated sometimes, as in Table A, i, 2 and 3, by the abbreviation 

 Bd. i or Bd. 2 just above the margin of each band, and sometimes 

 as in table B by a single arabic numeral followed by a colon and 

 the total number of scutes in the band. When the quadruplet 

 fetuses and the mother are dealt with, the number of the set is 

 indicated as A.ioi 9 or K^Oc?, indicating at the same time 

 the sex of the litter; the bands of the mother are labeled M and 



those of the fetuses I., II., III. and IV. When the mother or any 

 fetus is not tabulated the inference is that no anomaly is present 

 in the omitted individuals. Other schemes of tabulation, such 

 as the circular figures and those showing double scutes will be 

 explained in the proper place.
