(1641) Micromonacha lanceolata {Deville). 



Bucco lanceolata Deville, Rev. et. Mag., 1849, p. 56 (Pampa del Sacramento, 

 Upper Amazons). 



A male from Buenavista, Narino, is more heavily streaked below and 

 the ventral region is deeper rufous than in two specimens from Zamora, 

 southeastern Ecuador. This upper Amazonian species has not before been 

 recorded from the Pacific coast where its occurrence admirably illustrates 

 the type of distribution which I believe to have been evolved by the Andean 

 uplift.

(1646) Nonnula frontalis (ScL). 



Malacoptila frontalis ScL., Ann. & Mag. Nat. Hist., Ser. 2, XIII, 1854, p. 479 

 (interior of Colombia). 



A male collected by Fuertes at Algodonal, on the lower Magdalena River 

 is doubtless typical of this species. Two Panama R. R. specimens and two 

 from Cana, eastern Panama are much more deeply colored both above and 

 below and evidently represent a different race. It would, however, be 

 desirable to examine additional Colombian specimens before describing it. 



Algodonal, 1. 



(1650) Monasa flavirostris Striclcl. 



Monasa flavirostris Strickl., Cont. Orn., 1850, p. 47, pi. 48 (Peru). 



Evidently restricted in Colombia to the Tropical Zone at the eastern 

 base of the Eastern Andes. I have no Peruvian specimens for comparison.

(1653) Monasa morphceus peruana Scl. 

 Monasa peruana Scl., P. Z. S., 1855, p. 194 (Chamicuros, e. Peru). 



Specimens from Amazonian Colombia are evidently to be referred to 

 this race which, however, with its near ally, M. m. morphceus (cf. Hellm., 

 Nov. Zool., XII, p. 297), is not adequately represented in our collection. 



Florencia, 8.
