Janeiro.

I much regret that, owing to some unaccountable carelessness on my part, 

 Table IX, p. 315 of a recent ' Phil. Trans.' paper* was printed from my first 

 draft, and not from the final copy. To it there must be added : — 





Species and Marks. 



G-enus. 







Ceylon 











Ceylon. 



Rarity. 



and 



Earity. 



Wider. 



Earity.

This error, however, affords the opportunity of once more calling attention 

 to the extraordinary regularity with which the figures follow my suggested 

 law of rarity. The total of the omitted genera goes in perfectly regular 

 order, and so large an omission makes no difference to the final result. 

 There are two errors in the total given for Table IX, which should read 



I 310/1367 | 4-4 I 166/569 13-4 I 315/889 I 2 "8 



Addition of the omissions given above makes
