necessary to adopt a similar classification for the varieties in 

 Ceylon and to perhaps omit the Calabacillo group (which is very 

 rarely if ever, met with in this island) and give the Amelonado 

 variety a separate class, as it is on all estates so markedly different 

 in its shape, green-yellow colour and flat purple seeds from any 

 other Forastero type. 



In order to enable one to select the various types it will be 

 necessary to deal very fully with the characters of the fruit wall 

 and seeds. 



FRUIT WALL. 



Thickness. — The thinnest walls are found in the Nicaraguan and 

 •Caracas types and the thickest in the Forastero forms. The fol- 

 lowing figures show the thickness, lengths, circumferences and 

 weights of several fruit walls of cocoa pods grown at Pera- 

 deniya : —

It is obvious from these records that the most wasteful variety 

 of cocoa, as far as the thickness and weight of fruit wall are con- 

 cerned, is the Forastero-Cundeamor and the most economical the 

 Caracas or Nicaraguan type. 



Colour. — The outer surface of the fruit wall is, unripe specimens, 

 red or green, these changing during ripening to reddish-yellow or 

 yellow respectively. In the Forastero group the fruits show all 

 proportions of red and green inter-mingled with one another and 

 even the Criollo fruits may be yellow or red. In Ceylon, the 

 Amelonado variety is distinct in always having a green wall 

 changing to pale yellow on ripening. Usually all the fruits on 

 the same tree have a similar colour or distribution of colours, 



In Trinidad, as indicated, by the classifications of Morris and 

 Hart, each variety is sub-divided into red and yellow forms, and 

 the same applies generally to the varieties in other cocoa-grow- 

 ing countries.
