ricli purple^ the two lateral rectrices with narrow buff tips, 

 the central pair metallic greenish blue towards the tip. 

 Below dark greeu, each feather with a rusty-brown border, 

 broader towards the belly, which is almost entirely rusty brown. 

 Under tail-coverts purplish steel-blue, with broad rusty-buff 

 edges. Chin and throat glittering green in the middle. The 

 irregular shape of the glittering spot on the throat and the 

 rusty edges on the underside are probably signs of imma- 

 turity. Wing 71mm.; lateral rectrices 54, central 40 ; ex- 

 posed part of culmen 13'5. 



One specimen, evidently a male, found in a Bogota 

 collection of Humming-birds. The bill is sharply pointed ; 

 the mandible is distinctly turned upwards before the tip, 

 reminding one of Opisthoprora. The rectrices are very 

 wide, the lateral and central ones fully 12 mm. The purple 

 tail reminds one somewhat of Zudalia, which, however, has 

 the tail much longer. 



This species has apparently no very close ally. 



Mr. E. Hartert further submitted some other new South- 

 American birds, collected in Ecuador by Mr. Rosenberg. 

 He characterized them as follows : — 



Ceruomacra rosenbergi, sp. n. 



J ad. Above blackish cinereous ; a large concealed dorsal 

 spot of white. Wings and tail greyish black; tail without any 

 white tips. Bend of wing mixed black and white. Wing- 

 coverts with rounded white tips. Wing 63 mm., tail 51, 

 bill 19, tarsus 28. 



Cachabi, North Ecuador, 500 feet high. Named in honour 

 of the discoverer. 



This species is allied to C. tyrannina and C approximans, 

 but differs in having no white on the inner edges of tlie 

 wing, and in Laving no large white spot on the bend of 

 the wing. The tips to the wing-coverts are rather rounded, 

 the rectrices having no white tips whatever. 



Pyriglena berlepschi, sp. n. 



Entirely black, with a large concealed dorsal spot of white.
