FURTHER NOTES ON BIRDS 
third, or white-margined species, I gave the name of 7. albocris- 
tatus. 1 will further remark, that I do not see why Prince 
Bonaparte has adopted the specific name, purpureus, attached in 
manuscript by Cuvier, to the specimen of the green-crested species 
in the Paris Museum, in preference to the name buffont, long ago 
published by Vieillot. No MS. name, however venerable a one, 
can eyer claim any authority over a name which has once been 
defined in a published work. 
P. 259.—From the descriptions of Chrysococcya smaragdineus, 
given by M. Verreaux, it appears that the specimen described at 
p. 185 supra, is a female. M. Verreaux states, that the Gaboon 
specimens differ from Senegal ones, only in haying a shorter tail. 
He adds, that they arrive at the Gaboon in spring and disappear 
before the winter ; but as that river is exactly under the equator, 
it would have been well if M. Verreaux had informed us what 
months of the year are here referred to, there being two summers 
and two winters annually in equatorial regions. 
P. 262.—Barbatula flavimentum, Verreaux, is here described 
as new, the authors not being aware that it is synonymous with 
B. subsulphurea, Fraser. 
_ P. 264.—Haleyon badius, Verreaux. This is the species de- 
cribed at p. 134 supra, as “ Haleyon cancrophaga (Lath.)?”. It is 
certainly distinct from the true H. cancrophaga (Lath.), which, 
however, seems to be only known from Buffon’s Planches Enlumi- 
nées, 334. 
P. 269. — Melittophagus cyanipectus, Verreaux. The authors 
admit the resemblance of this species to MW. lefebvrei, Desmurs, 
which I had identified with it at p. 135 supra, but assert its dis- 
tinction on account of its smaller size and paler tint below. Be 
this as it may, the Jf. cyanipectus of M. Verreaux is certainly the 
same as M. variegatus of Vieillot, described in the Nouv. Dict. 
Hist. Nat., vol. xiv. p. 25, as found at Malimbe on the west coast 
of Africa. 
P. 271.—M. Verreaux remarks of his Izos ashanteus (Pyenono- 
tus ashanteus, supra p. 182), that it differs from 7. arsine (Pycno- 
notus barbatus, Desfontaines, mihi), not only in the yellowish under 
tail-covers, but in the lighter tint of the head, a character which I 
had not noticed when I had an opportunity of comparing these two 
birds.
