 410. " Iris black, bill black, lower mandible at basal half red or yellow." 



Of this species only two specimens were known to exist: Gould's t3'pe in the 

 British Museum (from unknown origin), aud a specimen in the Kiel Museum said 

 to be from Pari, a locality which proves to be quite correct. Mr. Hoffmanns is to 

 be congratulated upon having secured a good series of this rare bird. 



As pointed out by Berlepsch and Leverkuhn, A. nitidifrons is a near ally of 

 .1. aflinis (Gould), agreeing with it in the greyish green tail, in the coloration of 

 the under tail-coverts, aud in the throat being spotted in the same manner. The 

 adult males differ, however, at a glance in having the forehead and anterior part of 

 the crown of a beautiful glittering bluish green instead of dull bronze green; the 

 glittering rounded spots on the throat and sides of tlie head have also a decided 

 bluish hue, while they are pure golden green in A. affinis. Another striking 

 difference consists of the markings of the tail, the four outer pairs of rectrices 

 showing a broad, well-defined steel-black subterminal band on both webs ; in 

 A. affinis this is but slightly indicated on the inner web of the two outermost 

 tail-feathers. 



The females of A. nitidifrons lack the glittering patch on the head, the 

 forehead and crown being shining metallic green like the back, and the sjwts 

 on the throat are less bright and almost devoid of the bluish tinge. They are, 

 however, easily distinguishable from .4. affniis by the markings of the tail. 



6S. Wing 47— 50| ; tail 28—31 ; bill 15-ll6i mm. 

 ? ?. Wing 45—48 ; tail 25—27 ; bill 15—16 mm. 



The type differs from our series only by the white ground colour of the throat 

 being almost entirely hidden by the glittering bluish green apical portion of the 

 feathers, and in the strong golden bronze suffusion on the rump and upper tail- 

 coverts.

 They agree perfectly with specimens from Cumand, and British Guiana, being 

 much darker green both above and below than typical II. c. a/anus of S.E. Brazil. 

 New to the fauna of Para. 



82. Hylocharis sapphirina (Gm.)

2 SS ad., 1 S juv., 1 ? : 5, 7, 8, 20. xii. 05. Nos. 207, 284, 292, 390. "Iris 

 black." 



These specimens agree exactly with a scries from Surinam and Brit. Guiana 

 {11. yuiunensis Bone). If two geographical races of this species are recognised, 

 the name sapphirina must be retained for the northern form, Bnfifon's description 

 being most probably based upon Cayenne e.xamples.
