THE AMERICAN NATURALIST [Vol. XLIV 



23. The P-W family. The relationships of the mem- 

 bers of this family, so far as worked out, are shown in 

 the diagrams 23a, 23b, 23c and 23d. The persons in these 

 diagrams eome from the same general region and sev- 

 eral surnames are common, especially those indicated by 

 the initials P and W. The frequent recurrence of the 

 same four surnames in the paternal and maternal sides 

 of the ancestry of most of these albinos is testimony to 

 a wide spread consanguinity. Further details are re- 

 served for a later paper when it is hoped the pedigrees 

 can be extended and connected.
