4. rxEROprocurs. 345 



This bird in general colours approaches PteroptocTius albicolUs 

 of Chili, but is readily known by the pure white breast and mid-belly 

 and the curious pectoral spot. It is also considerably inferior in size. 

 The bill is short and straight, the culmen being straight nearly to 

 the extremity, and the gonys curved upwards rather rapidly towards 

 the point. It is compressed much as in P. alhkoUis. Tlio tarsi are 

 rather shorter and by no means so strong as in P. alhicolUs, and 

 their anterior surface is nearly smooth, the divisions of the scutella 

 being almost obsolete and nearly imperceptible. The claws are short 

 and curved. The wings are short and rounded, the fifth, sixth, 

 seventh, eighth, and ninth primaries being nearly equal and longest.

This peculiar genus contains two Avell-maiked sjjecies, both re- 

 stricted to Chili. It is characterized by the straight bill, in which 

 the nostrils open at the base by a narrow slit only, being covered 

 with a horny operculum, by the long slender tarsi, "and by the short 

 wings. The tail is of moderate length.
