“Professor Jameson’s specimens of this fine bird were obtained in the neighbourhood of Auca, on the road to
Nanegal, at about 6000 or 7000 feet elevation. They were feeding on the 4 lstremeria, Dature not being found in

that locality.” —Jameson and Fraser in Ibis, vol. i. p. 400.

The members of the genus Helianthea, distinguished by their star-like frontlets and luminous under-surfaces,
appear to range next to the preceding. Three of them (namely, ee typica, H. Bonapartei, and H. Eos) are quite
typical; but the H. Lutetie and H. violifera differ somewhat in their colouring, the lower part of the body of the
two latter species not being luminous, while they assimilate in all other respects. Dr. Reichenbach’s separation of

the H. typica and H. Bonapartei into a separate genus (Hypochrysa) cannot, in my opinion, for a moment be admitted.

Genus Heuianruea, Gould.
