TABLE 3 

 Further analysis of the data of table 2, 9 No. A24S {nearly or quite pure 



St. risoria) 



Total from 1st of clutch = 24cf : 22 9 (unknown, 4) ; 2nd = 16 cf :21 9 » 

 (unknown 13). 



^ The last egg of this period produced female twins. 



- There is an additional female twin. Reference to table 1 will show that 

 there were 13 second eggs of the clutch, predominantly female-producing eggs, 

 which were (in 12 cases) too iveak in development to permit a test of sex. The sex 

 of only 4 first eggs of the clutch is unknown; only 2 of the 4 were too weak to hatch. 

 This undoubtedly makes both the apparent number (21) and the proportion of 

 females from the second eggs of the clutch much too small.
