Rcmarlis. This specimen was presented to me by Count Hans von 

 Berlepsch as Catharus fuscater Lafr. It differs strikingly from speci- 

 mens of G. fuscater from Central America, of which Mr. Eidgway has 

 kindly sent me three examples. Of these he writes me: "I have com- 

 pared them with Lafresnaye's type and found them to be the same." 



It differs in dimensions from G. fuscater, being smaller, the wing 

 shorter and the tail longer; the bill is straighter, narrower, and a little 

 longer; the tarsi are very decidedly more slender and darker in color. 



C. fuscater is, much stouter in appearance, and the general coloring 

 is much darker; its upper plumage is entirely black; the throat, the 

 upper part of the breast, and the sides are blackish cinereous; the 

 white of the abdomen is much more restricted than in the new species. 



It is with much pleasure that I confer upon it the name of my friend, 

 Count Berlepsch.
