London: Henry G. Bohn, 1837. Profusely illustrated with 150 hand coloured plates (all present).
"New Edition" (2nd.) of the original 1770-1787 publication "brought down to the present state of the science with the systematic character of each species, synonyms, indexes, and other additional matter". Three volumes. Considered the better and more accurate edition.
Quarto, three-quarter brown morocco lettered in gilt over dark green cloth covered boards. Some rubbing to covers, front endpapers of volume I cracked over hinge, occasional minor foxing on text pages, plates clean and crisp and colours strong.
