INHERITANCE OF VARIATES IN THE ARMADILLO 149 



number. It is a simple matter to determine the probable erfor 

 and this deficiency of the former paper will be avoided in the 

 future. 



2. It has been objected that the title of the paper is misleading 

 in that it purports to deal with heredity when no data concerning 

 heredit}^, defined as the genetic relation existing between parent 

 and offspring, is furnished. Although I am unwilling to admit that 

 a study of fraternal correlation is foreign to the science of heredity, 

 I am willing to acknowledge that the failure to deal with the in- 

 heritance of these characters from mothers to offspring was a real 

 oversight. The present studies, however, should satisfy to a 

 large extent the demands of the critic in that it is shown that 

 practically all of the characters dealt with in the previous paper 

 are inherited directly from the mothers according to certain laws 

 that will be made clear in the body of the paper. 



3. It has been objected that a study restricted to the characters 

 of the banded region of the armor furnishes too limited a basis 

 for reaching conclusions of wide or general application. By way 

 of meeting this objection, I have worked out the data for all of 

 the other regions of the armor ahd for a number of other types 

 of characters as well. The facts concerning all of these characters 

 are in perfect harmony with those determined for the banded 

 region, and will be presented after a more thorough examination 

 of the banded region has been made. 



4. It has been repeatedly insisted by those interested in the 

 work, and to some extent by the writer, that experimental breeding 

 is essential to an analysis of the problems of heredity involved in 

 the present material. That breeding is far less essential than might 

 at first be supposed will be admitted, I believe, by those who take 

 the trouble to note the following considerations. A detailed 

 study of all the phases of inheritance exhibited by the characters 

 thus far studied shows that there is present no appreciable sexual 

 dimorphism. Not only are males and females alike with respect 

 to all somatic characters examined (except in the genitalia and 

 their accessories) , but the two sexes inherit equally strongly from 

 the mothers. Since there is no sex-limitation in the inheritance 

 of the characters studied the paternal contribution though un-
