ZOOLOGICAL LITERATURE. 
Progne cryptoleuca from Cuba is another species nearly allied to P. purpurea, 
but with more pure though concealed white about the anal region and on the 
anterior part of the rump. The wings and tail more highly glossed, and 
the latter somewhat more deeply forked. S. F. Baird, op. cit. pp. 273-277. 
Progne furcata from Chili is a third species allied to P. purpurea, but 
with the anal feathers dark brown at base. Wings and tail dull. The 
latter deeply forked. S. F. Baird, op. cit. pp. 273-278, note. 
Progne leucogastor is described as a fourth new species, from Southern 
'Mexico/ Central America, and probably the north-eastern part of South 
America, and is the P. dominicensis of most of the lists of birds from those, 
regions. It differs from that bird, however, being brownish beneath (with 
the exception of the white belly, the shafts of the feathers on which are 
dusky), a character possessed also by P. domestica (Vieill.), but this last is 
much larger. S. F. Baird, op. cit. pp. 274, 282, 283, notes. 
■ A variety of Atticora cyanoleuca from Costa Bica, and south along the 
Andes to Chili, is described under the name montana. S. F. Baird, op. cit. 
pp. 310, 311. 
Stelgidopteryx fidvigida is described as a new species fi^om Costa Bica. Its 
conspicuous light rump distinguishes it from all its allies except S. uropy- 
gialis, than which it is smaller and darker. S. F. Baird, op. cit. p. 318. 
ORIOLIDiE. 
Details of some specimens belonging to different species of the black- 
headed section of the genus Oriolua from Africa and Asia are given. T. 
Salvadori, Atti Soc. Ital. Sc. Nat. 4 Sept. 1804. 
Oriolus galhida is figured. J. Gould, B. G. B. part viij C. J. Sundevall, 
Sv. Fogl. pi. Ixvii. 
VlREONID^. 
Hylophilus acuticaudus is a new species from Venezuela, differing in its 
narrow pointed rectrices from all others of the genus that the author has 
seen. G. N. Lawrence, Proc, Acad. Philad. 1865, pp. 37, 38. 
TYRANNIDiE. 
Arundinicola citreola is described at great length as a new species from 
Chili, but apparently only differs in a very slight degree from the A. Jlavi-‘ 
ventris of D’Orbigny. L. Landbeck, Ann. TJnivers. Chile, April 1864 Arch, 
f. Natm'gesch. 1864, i. pp. 68-62. 
Philippi, E. A., and Landbeck, C. L. Monograpliie der 
Siidamerikanisclien Muscisaxicolinen. Arch. f. Natur- 
gesch. 1865, i. pp. 74-109. 
Fifteen species of the genus Mmcisaxicola are discrimi- 
nated and described at considerable length, four of them, all 
from the Chilian Cordilleras, as new, namely : — 
M. cinerea, known by having all the upper surface of a pale ash-grey (op. 
cit. pp. 80-82). 
M. ruhricapilla, olive-brown on the upper part of the head, with darlc 
rusty-red central spots, the back greyish-brown (op. cit. pp. 90-96).
