THE BIRDS OF HAITI AND THE DOMINICAN REPUBLIC 339 



logs or rested among low branches, and while singing perched among 

 limbs sometimes forty feet from the earth but always concealed 

 among leaves. The song resembles somewhat that of the gray robin 

 (Mimociclila a. ardosiacea) and suggests also that of the smaller 

 thrushes (Hylocichla) of the United States. It is given slowly and 

 clearly with decided intervals between the notes. From the other 

 thrush of the island the notes are easily told since they are much 

 more clear and distinct in utterance, and less broken. The alarm 

 note is wheury wheury wheury repeated usually three times with 

 great rapidity. 



Abbott says that in May, 1920, when on the slopes of La Selle 

 above Fonds Verettes he saw one of these thrushes but had no gun. 

 On subsequent visits he was not able to find it again. Bond collected 

 birds in breeding condition on La Selle in June, 1928. 



Structurally the present species is characterized by long, slender 

 tarsus and rounded wing, the wing tip being somewhat more rounded 

 than in Haplocichla aurantia of Jamaica, which hitherto has stood 

 alone in a monotypic genus. Haplocichla swalesi is so entirely 

 different in color from aurantia as to preclude the idea of close 

 association between the two other than their union in the same 

 genus. They are evidently not geographic representatives of one 

 stock as is so often the case with allied birds on West Indian islands. 



Following is a description of the type specimen : 



Mus. Cat. No. 264,707, adult male, collected in the Massif de la 

 Selle (altitude 1800 meters), April 15, 1927, by A. Wetmore. Entire

 and upper foreneck black streaked lightly with white; upper breast 

 blackish slate with faintly indicated brownish edgings; sides of 

 upper breast sepia; lower breast and sides bright hazel; abdomen 

 white; flanks and under tail coverts blackish slate, the lower flank 

 feathers and under tail coverts with light shaft streaks and edgings 

 of white. Bill orange rufous, extreme base of mandibular rami and 

 area about nostrils blackish; eye ring light orange; iris Rood's 

 brown; tarsus Rood's brown with a line of honey yellow down the
