Parula mornata is described os a new species from Guatemala, differing 
from P. pitiayumi (v. brasiliana) , with which it has hitherto been con- 
founded, by wanting the white bands on the wings and the ochreous throat. 
S. F. Baird, Rev. Am. Birds, pp. 169, 171. 
Basileuteriis cinereicollis is a new species received from Bogota by MM. 
Verreaux, resembling B. cor ojiatus, but differing in the colour of its crest and 
throat. P. L. Sclater, P. Z. S. 1864, p. 166. 
Granatellus pelzelni is an undescribed species discovered *by Natterer in 
‘Brazil (thus extending the range of the genus into South America), distin- 
guishable from 6r. venustus by the want of the narrow black breast-band and 
the outer rectrices not being tipped with white, and from G. sailed by its 
white throat. P. L. Sclater, P. Z. S. 1864, p. 606, pi. xxxvii. fig. 1. 
Diagnoses of the three species of this genus are added (pp. cit. p. 607), and 
a figure of G. venustus is given (tah. dt. fig. 2), copied from that of M. du Bus 
in his unpublished ^ Esquisses Omithologiques ’ (pi. 34). 
Turdid^. 
Turdus pilaris. A very fuU account of three colonies which had been 
formerly described by Herr. O. von Boenigk (Naumannia, I. iy. pp. 29-37) is 
given by Alexander von Homeyer, J. f. 0. pp. 289-296. 
Turdus pilaris and T. iliacus are figured. J. Gould, B. Grt. Br. part vi. 
Turdus gurneyi, sp. n., from Natal. G. Hartlaub, Ibis, 1864, p. 350, pi. ix. 
Turdus aUnceps is a new species from Formosa, nearly allied to T. castaneus. 
On the carpal edge of the wing is a rather conspicuous tubercle or wart ; it is 
of course an abortive wing-spur, which in Turdus dactylopterus, Bp., of Syria 
appears to have acquired a full development.” R. Swinhoe, Ibis, 1864, 
pp. 363, 364. 
Turdus coyijinis is described as a new species from Cape San Lucas, with a 
general resemblance to an immature T. migratorius^ especially its western 
variety, but has rather different proportions, is much paler beneath, with a 
greater extent of white on the belly and no black or dusky on the head, 
S. F. Baird, Rev. Am. Birds, pp. 29-31. 
Mimodchla schistacea is described as a new species from Cuba, with stouter 
bill and legs, and no cinnamon-red on the body. S. F. Baird, Rev. Am. 
Birds, pp. 37, 38. 
Platycichla is a new genus, with the general appearance of a Planesticus, but 
differing markedly in having a short and very broad deeply cleft biU, much 
depressed at the base and with moderate bristles. The feet are weak, the 
tarsi very short, being less than the middle toe and claw, and without trans- 
verse divisions. In external form the genus exhibits an approach to the 
Ampelidec, especially to Myiadestes. 
P. hrevipes (sp. nov.) is the type of the genus. A specimen from the coast 
of South America, probably from Brazil, is in the Smithsonian Museum. Two 
others are in that of the Philadelphia Academy. It may possibly be the 
Cichlopsis leucogenys of Cabanis (Mus. Hein. i. p. 64, note)., but it cannot be 
reconciled with the description of that genus and species. S. F. Baird, Revi 
Am. Birds, pp. 32, 33. 
Kittadncla (lege Cittacincla) auricularis is a new species from Formosa, with
