[Tardus surinamus Linnaeus, Syst. Nat. xii. 1. p. 297 (17(36.— ex Brisson : Surinam).]

 River," East Ecuador). 



No. 742. c? ad., 2. vi. 00. '• Iris dark brown, feet and bill black." 

 This specimen differs from a nnmber of skins from Bogota collections and the 

 Rio Napo by having a somewhat shorter and stouter bill, and a decidedly darker 

 rump and coronal patch which are deep tawny (Itidgw. v. fig. 1) instead of ocliraceons 

 (v. fig. 7). The tufts on the sides of the chest are pure white, as in T. s. napensis. 



14. Ramphocelus nigrogularis (Spix). 



Tanagra nigrogularis Spix, Av. Bras, ii. p. 35. tab. xlvii. (1825. — "ad flumen Solimoeus in sylvis 

 pagi St. Pauli ").

 Similar to specimens from the Peruvian Amazons, while others from Oosnipata, 

 South Peru, are rather larger.
