making a most interesting visit (May 1862) to the " Cays," where he found many sea- 

 birds nesting. In the meantime I went to the highlands of Quiche, Guatemala city, 

 Alotepeque, and Copan, and returned to Yzabal by way of Chiquimula, meeting Salvin 

 again on my way home. After I left he passed through the Altos, from Vera Paz, 

 staying at Totonicapam, Quezaltenango, and other places, and made two expeditions 

 to the Costa Grande : one to Retalhuleu, and the other to the lagoons of the coast and 

 the series of small lakes at Huamuchal, close to the frontier of Soconusco. Salvin, on 

 his third journey, arrived at San Jose in May 1873. He made his headquarters 

 again at Duenas, from which place he once more visited the forests of the Volcan de 

 Fuego, the Volcan de Atitlan, and the Altos, travelling thence to San Geronimo, 

 Guatemala city, and San Jose. On his way home he spent a week at Obispo, on 

 the line of the Panama Railroad, returning to England, vid New York, in June 1874. 

 On one of the earlier journeys to Guatemala, Salvin had been fortunate enough to be 

 able to train and secure the services of a native, Enrique Arce, who subsequently 

 went to Costa Eica, Chiriqui, and Veraguas on our behalf. 



In 1887-1888 I made an expedition to Mexico, visiting the Volcanoes of Popo- 

 catepetl and Ixtaccihuatl, Jalapa, Misantla, Vera Cruz, Puebla, Cuernavaca, Morelia, 

 Patzcuaro, Amecameca, Yucatan (Merida, Izamal, Ticul, Peto), &c. During part of 

 the time I had with me, as collectors, Mr. W. B. Eichardson, Mr. and Mrs. Herbert 

 H. Smith, and an Indian, M. Trujillo, all of whom did good work and continued to 

 obtain skins for us for some time after I left. Eichardson subsequently visited the 

 Mexican State of Chiapas (1897), the Eepublic of Honduras (1898), Guatemala 

 (Volcan de Santa Maria), and Nicaragua, and sent us many birds from those 

 countries. Mr. H. Eogers was employed by me to visit Costa Eica (1877), and 

 Mr. W. Lloyd and Mr. F. B. Armstrong investigated the provinces of Northern Mexico. 

 Dr. G. F. Gaumer, who accompanied me for a short time in 1888, added to our 

 collection many birds from Cozumel, Mugeres, Holbox, Euatan, and other islands 

 off the coasts of Yucatan and Honduras, as well as from the mainland of Yucatan. 

 Mr. F. Blancaneaux sent us various forms from British Honduras, Mr. C. F. 

 Underwood an extensive series from Costa Rica, and Mr. M'Leannan many birds from 

 the line of the Panama Eailway. The Mexican series purchased by us in 1889 from 

 Senor F. Ferrari-Perez, Director of the Museum at Tacubaya, and the North-American 

 collections acquired from Mr. Henshaw, Mr. W. E. D. Scott, and Mr. C. K. Worthen, 

 have been of much assistance in identifying many of the species, Professor Eidgway 

 having been kind enough to critically examine and determine all the specimens
