IL—_ON THE GENUS TANAGRELLA, Swatyson. 
Tue genus Tanagrella (changed by M. Cabanis into Hypoth- 
lypis), contains, as far as I am aware of, only the three species 
hereafter mentioned, the two first of which have been much con- 
founded together. The Motactlla campestris of Linneus (— Tana- 
gra ruficollis, Gmelin = Tachyphonus rufigularis, Laf. = Neornis 
cerulea, Hartlaub) has been lately added to the genus, but it seems 
to be more nearly allied to the genus Lowigilla, Lesson (— Pyr- 
rhulagra, Bp., Consp. Ay. p. 492) of which the type is Loxigilla 
noctis = Fringilla noctis, Linn. Tanagrella rufiguia, Bp., Compt. 
Rend. Ac. Sc. Paris, 1851, p. 76, I consider to be closely allied to 
Calliste punctata (Linn.), and to be more correctly placed in that 
genus.
