234 Mr. J. H. Gurney's List of n Cullcctwn 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 i)ilc 

 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 

 Gi lines, diam. 1 inch 1 line. 



381. PODICEI'S ? 



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. IIELIORNITIIID^. 



382. Heliohnis tulica^ Bodd. 



Inhabits the Pacilic 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 Trochilidoe, 

 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.

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 countrv.
