^ Spcoti/lo cunicularia, var. guar!clou)>eii.<ti.i, Ridc.way. This bird is merely a very dark local 

 fonn of the common species, though it dilfci-s very apprpciably in the sharper dcGnition, 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. dominicensi.i. Gmki.. (S. N. 296, S. domingnisis, i\vu.. Gi'.ay's Hand 

 List, 43, No. 438), not S. fu.ica, Vikill. (Gray's Hand Li.st, No. 439). The type is in the 

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

 (No. 787).
