the father. In another collection we would probably find the 

 disproportion swinging the other way. 



A similar survey of the figures shown in table 2, B, shows the 

 same state of affairs, except that there is a more equal distribu- 

 tion of maternal and paternal sets. The following sets may be 

 classed as maternal: C 27, C 32 (mixed), C 43, C 45, C 63 (mixed), 

 C 66, C 68 (mixed), C 75 (mixed), C 79 (mixed), C 80, C 95 

 (mixed), K 48 (mixed), K 82. The others are classed as paternal. 

 Counting the mixed sets, which have some maternal and some 

 paternal individuals as one-half each, we have 9^ cases maternal 

 and 10| paternal. This shght preponderance of paternal sets 

 accounts for the coefficient of correlation between females and 

 mothers being somewhat below the expected 0.5. It is actually 

 0.4261 ± 0.0558. 



It will be noted that this data shows even fewer evidences of 

 blended inheritance than that given for the banded region and 

 more striking evidences of a very typical sort of alternative or 

 exclusive inheritance. If blending occurs at all it plays only a 

 very minor role in the inheritance of these scute aggregates. 



3. CORRELATIONS IN INDIVIDUAL TAIL RINGS 



Little need be said by way of preface to tables 3 and 4 which 

 give respectively the polyembryonic and the uniparental correla- 

 tions computed from the data given in table 2. 



Analysis of table 3 shows substantially the same conditions 

 that were brought out in connection with the individual bands in 

 the banded region. A comparison between the two regions may 

 readily be made by placing together this table and table 10 (page 

 882) of the former paper which I have referred to several times. 

 Although in both the bands and the rings the polyembryonic cor- 

 relation is very high (0.9211 for the bands and 0.9109 for the 

 rings) when considered in the aggregate, that of individual bands 

 or rings falls markedly lower, that of the bands on the average 

 being 0.6459 and that of the rings 0.6263. The resemblance 

 between the two types of correlation in these two widely separated 

 regions of the armor is remarkably close an'd probably represents 

 a rather general relation that will be found to apply even more
