NOTE TO PLATES X AND XII. 



In the previous instalment of the article entitled " Contributions to 

 the Comparative Moiphologj of the Central Nervous System," refer- 

 ence was made in several instances to plates which it was impossible to 

 distribute with that number. In making up the present number it 

 became necessary to rearrange the figures upon the plates, causing the 

 following changes: 



For " Plate X, Fig. 5," read " Plate XII, Fig. 10." 



For " Plate X, Fig. 14," read "Plate X, Fig. 9." 



Elsewhere substitute "Plate XII " for "Plate X." 



For " Plate XII, Fig. 3," read " Plate XII, Fig. 8." 



On page 27, for " Fig. 7, Plate III," read " Plate X, Fig. 6."
