* Mr. Bulliard has well figured several sorts of this variable species 
in his 518th plate, all of which have not occurred to me, but I have 
fouud several which still remain to be figured, and have no doubt but 
several others may yet be found. On this account, and from the diffi- 
culties which I know this variable species has occasioned, particular 
descriptions are added to each variety ; for by this means only can we 
hope to get them properly arranged. at as aes
