under tlie name of Petrochelidon albUinea, and about the same time Mr. Salvin discovered 

 the species in various parts of Central America and named it P. Uttorea ; but he 

 acknowledges that Mr. Lawrence's description was published before liis own, and he 

 adopted the name given by the last-named author. 



The range of this Swallow throughout Central America is almost continuous. The 

 late Colonel Grayson found it in Mexico, at Mazatlan, and specimens from the State of 

 Vera Cruz, collected by Mr. Boucard, are in the British Museum. In British Honduras 

 it was procured by Messrs. Salvin and Godman on the Belize Uiver and the Cays of the 

 coast. Although not yet recorded from Yucatan, Mr. G. F. Gaumer has recently sent a 

 specimen from Jolbox Island, off the coast of that province. 



In Guatemala the species was met with by Messrs. Salvin and Godman at several 

 places, Peten, Taxha, Bio Dulce, Iluamuchal, Chiapam, and San Jose de Guatemala. 

 At San Salvador in La Union, and again at Amapala in Honduras, it has been noticed 

 by Mr. Salvin, while it is also recorded from Nicaragua. Mr. Zeledon includes the 

 species in his list of Costa-Pdca birds, and Messrs. Salvin and Godman procured a 

 specimen at Punta Arenas, which is now in the British Museum. Mr. M'Leannan sent 

 the original specimens from Panama, and Mr. Salvin found it In'eediug on the Chagres 

 River in that State. 



As before mentioned, we cannot separate the Peruvian bird specifically from 

 T. alhilinea, and it probably occurs in Ecuador also. 



Messrs. Salvin and Godman believe the species to be resident in every country 

 throughout Central America; and it appears to frequent inland waters as well as the 

 sea-coast, breeding in old Woodpeckers' holes in the snags of rivers in British Honduras. 

 At Matachio, on the Chagres lUver, a nest with young birds was found by Mr. Salvin in 

 May 1873, in an old post, a hollow palm which had once served to support the roof of 

 a hut. 



The late Colonel Grayson has given the following account of the species in TTestern 

 Mexico : — 



" This handsome little Swallow is common at Mazatlan, where it is a constant 

 resident, one among the few Swallows that is not migratory. At all seasons of the year 

 its twitter may be heard about the eaves of the houses, or the spacious corridors of the 

 peculiarly constructed Moorish Mexican haciendas. We often sec it skimming along 

 the streets, at times almost touching the pavement in its pursuit of Hies. Its custonuiry 

 haunts are near or about large towns or haciendas, and raicly have 1 sccmi it lar from 

 some human habitation. In April it commences to form \\n: ncsl, usn.i'.ly l)i'nc;illi llu' 

 eaves of houses or in holes in the wall, often in the hollow tubes for convcyiiiL;- lln' water 

 from the flat roofs of the buildintrs. Thev are very sociabh* in tlicir lialiiis, and inav 

 often be seen in. considerable numbers perched upon the roofs of the honscs."' 



To this note Messrs. Salvin and Godman append the follow in l;- remarks : — 



"This account of the habits of T. olbiUnea hanlly agrees ^\ ith our e.vperieiu'e. We 

 only found them along river-courses or frequenting lagoons or lakes, a favourite ])ereh
