 Manikup de Cayenne Daubenton=Pipra albifrons Gmelin. — Pithys Vietllot, Nouv. 

 Diet. d'Hist. Nat., xxiv, 1818, 112 (diagnosis but no type); xxvi, 1818, 520. Type,

 Hein., ii, 1859, 8. Type, Pipra albifrons Gmelin. (Colombia to Guiana, Peru, and 

 central Brazil; two or three species.) 



Notwithstanding its unquestioned priority, the name Manikup is so obviously both 

 barbarous and cacophonous that it should not be employed as the generic term.

 Ac. Nat. Sci. Phila., June 2, 1899, 209 (new name for Heterocnemis Sclater, preoccu-

 as, unfortunately, no memorandum was made of the species upon which it was based. 

 No species of Sclateria is represented in the U. S. National Museum collection.
