Variations in structure in any given species of animal, range from the most minute structures that can be examined by microscopic or other technical means, to the gross items that are easily discernable with the unaided eye. Such variations are of extreme interest to the biologist and serve to forcibly remind him of the vast range of variations possible in any given species. The report on the present specimen seeks, not to present it as a monstrosity of the strange and unusual type, but rather to relate it in some measure with the usual development in chicks and to some of the rather obvious problems involved.
