ZOOLOGICAL LITERATURE. 
Mhamphoe<^nus collansy Natter.,” is an undescribed species from Brazil. 
Id. op. cit. pp. 84, 157, 158. 
Cercomacra approximans and C. rujicauda are two new species from Brazil. 
The Jirst is very like C. tyrannina, Scl., but with a shorter bill and longer 
wings, and the female has the front and sides of the head rust-colour. 4'he 
second is very near to C. melanura (M^ndtr.), but difl'ers in the black breast 
and abdomen, the rust-coloured flanks, abdomen, and vent, the entirely rufous 
tail, and in other points. Id. op. cit. pp. 85, 158, 159. 
Gymnocichla cMroleuca is a new species from Costa Bica and Honduras, re- 
sembling G. nudiceps (with which it has been confounded), but remarkable 
for having a stronger bill and the bend of the wing entirely white. P. L. 
Sclater & O. Salvin, P. Z. S. 1869, pp. 417, 418. 
^ Percnostola minor and P. leucostigma. Natter. & Lafresn.,” appear to be 
two undescribed species from Brazil: the ^rst very like P. funehris (Licht.), 
but smaller, with shorter bill and wings, the head in the cf scarcely crested, 
and the abdomen in the $ much paler, the margins of the wing-coverts also 
being narrower j the second is said to be identical with Turdus rujifrons, 
Gmel., and the reason for changing its specific name is not made clear. A. 
von Pelzeln, Orn. Bras. pp. 86, 159-161. 
Heterocnemis albiventris is an undescribed species from Brazil, though it is 
possibly the cf of Ilerpsilochmus argentcduSy Des Murs (Voy. Castelnau, 
Zool. p. 68, pi. 17. lig. 2). It difl’ers from II. neevia (Gmel.) by the nearly 
white lower surface and the outer rectrices not being tipped with white. 
Id. op. cit. pp. 87, 161, 162. 
“ Myrmeciza squamosa, Natter.,” is an undescribed species from Brazil, like 
M. loricata (Licht.), but with pure white terminal spots on the wing-coverts, 
the throat black, as is the upper breast, with white edges to the feathers, and 
narrower greyish-white superciliary streaks. It is Formicivora loricata, 
M^in^tr. (Mem. Ac. St. Petersb. 6 ser. iii. p. 470, pi. 4. fig. 1) {nec Licht.). Id. 
op. cit. pp. 87, 162, 163. 
Ilypocnemis macidicauda and II, margaritifera are two undescribed species 
from Brazil. They/r*-^ similar to II. melanopogon, Scl., but smaller, tlie mid- 
dorsal feathers white at the base, and the rectrices more broadly tipped with 
white ; the second resembles II. neevia, but has nearly round white spots on 
the black back, and the ground-colour beneath white. It is perhaps the c? of 
Phopotera punctulata, Des Murs (Voy. Castelnau, p. 53, pi. 17. fig. 3). Id. op. 
cit. pp. 89, 164-166. 
“ Pithys ci'istata (Natter.) ” and P. griseiventris are two undescribed species 
from Brazil, neither of which is comparatively diagnosed. Id. op. cit. pp. 89, 
166, 167. 
Grallaria princeps is a new species from Veragua resembling G. guatema- 
lensis, with which it has been confounded (P. Z. S. 1867, p. 146), but with a 
stouter bill, the body darker above, and the belly of a deeper rust-colour. A 
note on the distribution of the five species allied to G. rex is added. P. L. 
Sclater & O. Salvin, P. Z. S. 1869, pp. 418, 419.

Ortlionyx spaldingi is a new species from Queensland, distinguishable from 
O. spinicauda by its greater size and jet-black plumage. E. P. Bamsay, P.Z. S. 
1868, p. 386. Figured. J. Gould, B. Austral. Suppl. pt. v.
