There is a monstrosity in Mr. Brookes' s collection, injured when 

 young, so as to produce a flat-topped keel. 



The variety cervina is by mistake numbered as if it was intended to be 

 considered as a species. This part was printed during my absence from 

 England, which I hope will be taken as an excuse for several other minor 

 errors. The numbers should consequently be altered to No. 26, inclusive.
