The adnlt female iif similar to the male, but sniiiller, loss dark auij o'reeuer 

 on the head and n])])er tail-coverts, the ijlitteriug spot on the throat smaller, the 

 feathers of the chin white, blackish at base, only a patch in the middle of the 

 abdomen buif. Salvin's description of the female in Cat. B., xvi., p. 166, seems to be 

 that of an immature l)ir(l. Wing in the males 2'5 to 2'6 inches, in tiie females 2-27 

 to 2-3 ; tail in the former l-()5 to 1-75, in the latter Too. 



This species shows that the genera Hflinnr/elus and Hi'liotrjfphd are very closely 

 allied, as it somewhat connects them. 



31. Urosticte benjamini (Bourc). 

 One specimen from Rio Pescado, Ecuador. 



32. Urosticte ruficrissa Lawr. 



An admirable series from the Rio Pastassii, collected in Antriist, when they were 

 in good plumage. 



33. Adelomyia melanogenys (Fraser) and 



34. Adelomyia maculata Gonld. 

 There are generally, and also recently in the Gatidoyue of Birds, xvi., pp. 169, 

 170, two different forms united under the name of Adelomt/ia melanogenifs, one the 

 true A. melanogem/s (described from Bogota by Fraser, P. Z. S., 1840, p. 18, type in 

 the Liverpool Museum), of which ^4. sabinne (Bourc. & Muls.) is a synonym, and 

 A. mcictdata (described from Ecuador by Gould, Mon. Trocli., iii., pi. 199). 



Mr. Salviu {Cat. B., xvi., p. 17t)) is, no donbt, right in saying that the larger 

 size and longer bill, which are said to distinguish A. maculata, are not constantly 

 distinct, bat there are other characters that serve to separate the two species. 



In A. melunogi'nys the pale basal portion of the rectrices is small, restricted to 

 the paxt of the tail which is hidden by the under tail-coverts, and brownish bntf of 

 colour. Ill A. maculata, the pale portion is lighter and of a real buff colour, and 

 extends far beyond the tail-coverts and over half or more than half the length of the 

 rectrices. 



In A. maeulat'i tiie Imti' tips to the rectrices are larger, in .-1. inelanoyeni/s they 

 are smaller. 



As a rule A. nwlanogi'ni/s is deep green above, while A. maculata is distinctly 

 golden green or bronzy green above. This character, however, seems to vary 

 occasionally in A. nuiruUitn, but all A. mehtnoijciiiji^ from Bogota s(!em to have the 

 upper parts dark green. 



Our figures on p. 56 will illustrate the differences. They are most accurately 

 done from specimens sent by Mr. Baron. 



This gentleman collected A. melanoqi'iiijs on the Kio Pastassa, cast of the 

 Andes, at elevations of from 5U0iJ to 7UUt) feet, while he found A. maculata west 

 of the Andes, on the road from Lqja to Santa Rosa and Guayaquil, at elevations 

 of from 5000 to 7nOii feet. He further assured ns that tlic two species had different 

 call-notes. 



35. Phlogophilus hemileucurus Gould. 

 A single specimen with a dark outer edging to the white tip of the lateral 

 rectrices, not sexed, from Ecuador.
