A distinctly marked species of this singular group of Dendroco- 
laptine, easily recognizable by the clear elongated spots occupying 
the centre of the feathers of the breast and back. These spots are 
narrowly surrounded with black, and broadly margined outwardly 
with the general brown ground-colour. Its size is nearly that of X. 
procurvus, but the bill is rather shorter and more regularly curved. 
I may add that I possess examples of all the five species described by 
M. de Lafresnaye in his account of this group (Rev. de Zool. 1850, 
p- 373 et seq.), and two additional, namely the present and another 
which I consider new*.

Several ex. ‘“ Irides hazel.’’

Two ex. “Irides hazel; bill black ; legs and feet lead-coloured.” 
38. Srrrasomus ERITHACUS (Licht.). 
Two ex. “Irides hazel.” This bird seems scarcely recognizable 
from Eastern specimens, except by the slightly different tinge of 
chestnut on the rump and tail. 
39. SYNALLAXIS PUDICA, Sclater, P. Z.S. 1859, p. 191. 
Several ex., not in very good condition, but seemingly sufficiently 
like Bogotan skins. “ Irides whitish.” 
40. THAMNOPHILUS TRANSANDEANUS, Sclater, P. Z. S. 1855, 
p. 18. 
Many ex. of both sexes. ‘“‘Irides red; bill black ; legs and feet 
blue: found near the ground in the deep bush.”

Three ex. ‘Skulking about in the underwood.”

Three ex. Only differing from New-Granadian birds in having 
the throat rather whiter: erroneously referred before to D. mentalis.
