 cember. 



The Mexican bird, ^S. /. torquata (Linne), in the adult plumage, 

 always has immaculate under tail-coverts; the lining of the wing is 

 also less spotted with dusky. Birds from Paraguay and thence north- 

 ward to Panama always have some slaty spotting or barring on the 

 under tail-coverts and under wing-coverts, even when fully adult. 



On examining a large series of S. torquata, we find that the Paraguay 

 and Uruguay forms are more or less intermediate, sometimes approach- 

 ing closely to 8. t. stellata (Meyen), showing considerable white spotting 

 and barring on the outer webs of the secondaries, but, on the whole, 

 probably nearer the Guiana form, for which there is a later name — 

 S. t. caesia (Reich enbach). 



100. Chloroceryle Americana Americana (Gmelin). 



Five specimens, both sexes. Vicinity of Paramaribo, February, 

 March, April, and December. 



101. Chloroceryle inda (Linne).
