[June 19, light drizzling raiu, which generally lasted from two to four days, and with increasing cold, until the thermometer is said to have fallen at one time to 61° Fahr. In January 1879 there were four moderately heavy rainfalls, with strong northers and cold nights. One very heavy rainfall occurred on February 23rd, with a considerable sprinkling of hail. The hailstones were quickly gathered up and placed in bottles in Izamal by many persons, who thought they could be saved. There were five northers, each of which brought light rain. From February 26th to May 23rd no rain fell, and often the sky was entirely clear for weeks at a time, and in fact rarely was a cloud to be seen. The heat in the day gradually increased, until it was almost intolerable in April and May. On account of the dry air and clear sky the radiation was so great that the nights often became disagreeably cool, though generally most delightfully pleasant and balmy. The birds disappeared as the dry season advanced, except a few of the common resident species, which lived about the ranches and at the aguadas, where water was to be found. On the 23rd of May the first of the summer rains occurred, which was soon followed by daily showers at midday. All nature changed as if by magic ; new leaves grew, and the forests were again populated with sweet songsters, which gave life and joy to every thing. In June the rains began at 11 A.M. and ceased at 2 P.M., rarely beginning earlier or continuing later. In July they began at 10 A.M. and lasted until 3 or 4 P.M., but never earlier. In August they began at 10 A.M. and lasted until nightfall, and sometimes later. During these three months there were from five to eight days in each month upon which no rain fell. The heat was almost insupportable even for the natives. Yellow fever raged in most of the interior towns. In September the rains began at 8 or 9 A.M., and often lasted until midnight, and not unfrequently all night. The weather became milder. Insects became exceedingly scarce, and the birds were not fit to skin. Reptiles were about the only things to be found. Mollusks are exceedingly rare in Yucatan : not one species can be said to be common. During the first twenty-seven days of October 1879 rain in torrents fell almost incessantly. The sun was seen on four days, and the stars appeared in patches on five nights. Not five consecutive hours passed during the twenty-seven days without rain. Yellow fever gave place to intermittent and bilious fevers. Insects were rarely seen, and the birds again almost entirely disappeared. The rains seem now to have ceased as they began ; whether the rainy season is over remains to be seen. On account of the heavy rains or other cause, the birds which are here now are worthless for skins, as the feathers are not yet grown. Meleagris ocellata will probably have its full plumage by December, and will continue in good plumage until June." The chief localities in which birds were collected by Mr. Gaumer are as follows :- " (1) Progreso is the port of Merida, situated on the north coast, six leagues to the east of the old port of Sisal. The country is low aud marshy for nearly two leagues inland ; and in times of the northers the greater part of this distance is inundated by the rise of the |
