The discrepancies between the tallies as reprinted exactly above and 

 Chenu's list are so great that it does not seem reasonable to refer 

 theui merely to carelessness. In the absence of Chenu's original or a 

 copy of it, and from the fact that the tables as reproduced b}' me 

 from tiie Sydney co])y are marred by engravers' errors — have two spe- 

 cies without any specific name at all, and have thirty-six species with 

 different generic names from those cited by Chenu— I conclude that 

 the Sydney tables are an early issue of engravings which were later 

 corrected and completed, and that it was from one of the altered copies 

 that Chenu's badly printed list was taken, adding a numi)er of errors 

 of its own. 



As illustrating engraver's errors in the Sj'dney tables, 1 need only 

 mention as misspellings such words as coocinea for coccinea^ palatarn 

 for pal((t}nn^ and ostrhi for ostrea. 



Other errors of the engraver consist in reversi-ng the order of words 

 as indicated ))v the English trivial names, putting the varietal name 

 before the specific name, as fusca spicatus and n'xp'a splcatus for 

 spicaiiis xnr. fi'sc(( and .sy;/Vv//^/,y var. nigra. In one instance the name 

 intended for the specific name and the descriptive phrase have changed
