234 Mr. J. H. Gurney's List of a Collection of Birds 
Fam. VI. COLYMBIDiE. 
380. Podilymbus podiceps (Linn.). (N. A.) 
This is a resident species at Duefias, It breeds in May, 
making a nest amongst the reeds of the lake, consisting of a pile 
of flags heaped up so as just to raise the edge of the structure 
above the surface. The eggs are generally half-immersed. They 
are from two to four in number, and are of a chalky exterior on 
an under surface of bluish green ; they measure, axis 1 inch 
6| lines, diam. 1 inch 1 line. 
381. Podiceps - ? 
A small Grebe is common on the Lake of Duefias; but speci¬ 
mens have not yet been obtained. Its general appearance and 
habits are much the same as in the European P. minor , but it is 
smaller in size. 
Fam. VII. HELIORNITHIDiE. 
382. Heliornis fulica, Bodd. 
Inhabits the Pacific coast, being found in the submerged 
swamps underneath the trees. The only specimen obtained was 
swimming in the water, near the village of Santana Mixtan. 
In concluding our list, we beg to acknowledge the assistance 
we have received from Mr. Gould in determining the Trochilidce , 
and from Mr. Gurney in making out the species of Accipitres . 
Although we have enumerated 382 birds as occurring in Central 
America, the catalogue is still in many particulars very incom¬ 
plete, and we have no doubt that future researches will make 
great additions to it.

in South-eastern Africa. By J. H. Gurney, M.P., F.Z.S. 
(Plate VII.) 
The following is a list of a series of Birds of Prey, Goatsuckers, 
Kingfishers, Cuckoos, and Water-birds recently received by me 
from the colony of Natal, to which I have added the names of a 
few species belonging to the same groups from two other col¬ 
lections made in the same country.
