Doctor Cabot has published, in the Boston Journal of Natural History, an account of his observations upon one rare and splendid bird, the ocellated turkey, of which one stuffed specimen at the Jardin des Plantes, and another in the collection of the Earl of Derby, are the only two known to exit, and of which, besides obtaining a stuffed specimen, we succeeded in transporting two living birds from the interior, and embarking them for home, but lost them overboard on the voyage. I have hopes that he may be induced to publish a full account of his observations upon the ornithology of Yucatan. In the mean time I give in the Appendix a memorandum of about one hundred birds observed by him in that country, which are also found within the United States, and have been figured and described by Wilson, Bonaparte, Audubon, and Nuttall; of others, which are well known to the scientific world for their striking brilliancy of plumage, having been observed in different parts of South and Central America, but are known only by skins prepared and sold in the country, and whose habits have never been described; and a third class, more important to the naturalist than either of the others, comprising birds entirely unknown until discovered by him in Yucatan. The memorandum is accompanied by a few notes referring to the places and circumstances under which they were procured; and in referring to them in the Appendix, I would take occasion to say that some of the most really important matter in this work is to be found in that place, for the sake of which I have considered it expedient materially to abridge my narrative. But to resume. We stopped that night at Tixmeach, eight leagues distant, a neat village with a well one hundred and forty-four feet deep, at which every woman drawing from it left a handful of maize for a cantaro of water, and we paid a medio for watering our horses; and setting out before daylight the next morning, at half past nine we reached Peto, where we found Mr. Catherwood and our luggage on the hands of our friend Don Pio Perez. Peto is the head of a department, of which Don Pio Perez was gefe politico. It was a well-built town, with streets indicated, as at Merida, by figures on the tops of the houses. The church and convent were large and imposing edifices, and the living of the cura one of the most valuable in the church, being worth six or seven thousand dollars per annum.
