in general appearance, but readily distinguished by the white outer tail- 
feather and much purer white of the under parts. It differs also in other 
respects from the remaining species of this genus. S. F. Baird, Rev. Am. 
Birds, p. 69. 
Drymccca valida and D. iodoptcra are described as new species from the 
Bjour-country. T. von Heuglin, J. f. O. 1864, pp. 258, 259. 
Dnjmmca (?) troglodytes is described as a new species from Central Africa. 
O. Antinori, Cat. Ucc. Affr. centr. p. 38. 
JEremomela (?) elegans is described from the Djour-country. The propor- 
tions of the remiges correspond with the generic characters, but the inner 
toes are somewhat shorter than the outer. T. von Heuglin, J. f. O. 1864, 
p. 259. 
Eremomela (?) canescens is described as a new species from Central Africa, 
wanting the white ring round the eye. O. Antinori, Cat. Ucc. Affr. centr. 
p. 38. 
Motacillid^. 
Notiocorys is the name of a new group established for the reception of An- 
thus rufus of Lawrence (from Panama), and characterized by its short, rounded 
wings, the points of which are formed by four outer primaries of nearly equal 
length. S. F. Baird, Rev. Am. Birds, pp, 151, 163, 166. 
Vediocorys is another new group, characterized by its short, rounded wings, 
the points of which are formed by five outer primaries, the first shorter than 
the third. It comprehends Anthus hogotensis of Sclater, from Bogota and 
Ecuador, and a second species, supposed to be from Uruguay, similar in ap- 
pearance to Neocorys spraguii, but having differently formed wings and a 
rather different coloration. This second species is left unnamed. S. F. Baird, 
Rev. Am. Birds, pp. 161, 163, 167-169. 
Troglodytid^e. 
The genus Rhodinodchla heretofore generally placed among the Den- 
drocolaptidee, appears to belong truly to the Oscincs, and possibly to the 
Troglodytidm ; and Dr, Sclater is inclined to place it very near Heleodytcs,

1864, p. 345. 
Campylorhynchus megalopterus of Sclater {passim, except Proc. Acad. Philad. 
1856, p. 264) is identical with C. pallescens of Lafresnaye (Rev. Zool. 1846, 
p, 93), while C. pallescens of Sclater is C, halteatus. S. F. Baird, Rev. Am. 
Birds, pp. 101-103. 
“ Cyphorhinus lawrencii, Scl. MS.”, Lawrence, Ann. Lyc, N. York, viii. p. 6 
(=C. cantans, Lawr. olim, nec Gmel.), is now for the first time completely 
described. It resembles C. phtxocephalus, but has a brighter chestnut breast 
and cinereous belly. P. L. Sclater and O. Salvin, P. Z. S, 1864, p. 346. 
Heterorhina is proposed as the name of a group of some five species, formerly 
comprehended in the subgenus Microcer cuius, with the Cyphorhinus leucostictus 
of Cabanis as its type*. The chief characters of the new group are, tail firm

page we have “ Heterorhina, Baird. (Type Scytolopus prostheleucus, Sclater)” !
