? , Rio McClelland Settlement, 22nd Jan. ; ? , 24th Jan., 1905. 

 Iris — black ; bill and legs — drab. 



The earliest date I remarked the appearance of Meyen' s Martin 

 was 30th October, when I saw a pair on the scrub-covered slopes 

 of the Sierra Carmen Sylva, above San Sebastian Settlement. 

 On that day I also saw my first butterfly {Tatochtla argyrodice). 

 There were Martins, however, at Rio McClelland Settlement 

 earlier than this, from what Mr. Clarke tells me. 



In summer these birds are plentiful everywhere at the lower 

 altitudes, and they have an abundant food supply in the myriads 

 of midges ( Ghironomidce) and other winged insects which 

 swarm at this season. On horseback there are usually some in 

 attendance, following one to snap at the flies one carries with 

 one, or disturbs by the way. 



I observed them breeding in hollow trees in the valley of the 

 Rio McClelland.
