I am indebted to my friend Professor Sereno Watson, of Harvard, for the identification of species, which to the number of sixty he has already determined from some five hundred that he collected in the Departments of Livingston and Izabal. I did not myself make any collection, but noted the genera that were familiar to me as I travelled through the country. So little has been published about the Guatemaltecan Flora that I have ventured to add these notes to Professor Watson’s list.

A LIST OF WORKS RELATING TO CENTRAL AMERICA.

A full bibliography of works that contain information about the region through which we have been travelling together would fill a volume much larger than the present; but the following brief list of some of the more important titles may aid those who are interested in the past history or the future prospects of the tropical part of this continent. I have not thought it worth while to mention those unprinted works not at present accessible to the public, nor the ephemeral publications of simple tourists:—

Acosta, Fr. José de. Historia natural y moral de las Indias. Sevilla, 1590.

Adam, Lucien. Études sur six Langues Américaines, Paris, 1878.

⸺ Du parler des Hommes et du parler des Femmes. Paris, 1879.

Alcedo, Antonio de. Diccionario geografico-histórico de las Indias occidentales ó América; es á saber; de los reynos del Peru, Nueva España, Tierra Firme, Chile y Nuevo Reyno de Granada. Madrid, 1786-89. 5 vols. An English Translation, with Additions, by G. A. Thompson, was published in London, 1812-15. 5 vols.
