 Gmel. S. N. 292, sp. 28, — and of other authors referring to the South American bird. 



2 Speotyto cuniculciria, var. guadeloujKnsis, Ridoavay. This bird is merely a vei'y dark local 

 form of the common species, though it differs very appreciably in the sharper definition, greater 

 extent, and more intense tint of the brown markings of its plumage. 



I have been unable to find any description of this form, and believe it to be unnamed. It 

 is certainly not the S. clominicensis, Gmel. (S. N. 296, S. domingcnsis, Mull. Gray's Hand 

 List, 43, No. 438), not S. fusca, Vieill. (Gray's Hand List, No. 439). Tlie type is in the 

 collection of the Boston Society of Natural History, and belongs to the Lafresnaye collection 

 (No. 787).
