* The following are the indications of that obscure species, the Mexican Ibis:— 
Tantalus mexicanus, Gmel. Syst. I, p. 652, sp. 18. Lath. Ind. II. p. 704, sp. 4. 
Ibis mexicana, of later compilers. Ibis acalot of French compilers and Dictionaries.

This bird is said to inhabit Mexico: it will not be superfluous to remark, that the 
proportions assigned to it are much larger than those of our Ibis falcinellus.
