Dr. P. L. Sclater on new Tyrant-Birds from Ecuador. 313 



as the latter name was previously given by Reichenbach to Myiobius 

 ncevius*, for which and its allies I venture to employ it. 



Fam. Psittacid^e. 

 9. Urochroma stictoptera. 



Psittaceo-viridis : alls extus nigris, macula in mediis tectricibus 

 roseo-rubra ; remigum marginibus externis et secundariis dorso 

 proximis viridibus : caudce rectricibus intus paululum aure- 

 scentibus : rostro pallido : pedibus fuscis. 

 Long, tota 6'0, alse 5"0, caudse 2*5. 

 Hob. In Nov. Granada int. 



Obs. This parrot appears to belong to the group called Urochroma 

 by Prince Bonaparte, but is quite different from any known member 

 of that section. The tail is nearly square at its termination, the 

 two medial rectrices being slightly acuminated, the others rounde d, 

 but presenting the appearance of being rather worn. 



On Two New Species of Tyrant-birds from Ecuador. By 

 P. L. Sclater, M.A., Ph.D., F.R.S., Secretary to the 

 Society. 

 I am indebted to Mr. Gould's kindness for two specimens of Ty- 

 rant-birds from a collection recently received by him from the high- 

 lands of Ecuador. They are of nearly allied species, but stand best 

 in the two neighbouring sections of Ochlhoeca and Mecocerculus. 

 By the latter name I propose to replace Myiarchus (Bp., nee Cab.), 

 using it as a generic title for Fluvicola leucophrys, Lafr. et D'Orb., 

 and its allies.
