Excerpt from A Natural History of the British Lepidoptera, Vol. 4: A Text-Book for Students and Collectors

There is one point in particular, out of many others, in which the work of these authors far surpasses our own, and that is in their mode of treatment of the variation of the species. Their own immense collection, the visits paid by Dr. Jordan to all the leading collections on the,continent, the loan of types from out lying countries, &c., have permitted them to attempt to deal with this phase of the subject on general biological grounds, and, in some cases, they have thus been enabled to discriminate between the literary type and the biological type, and, having determined the latter, so far as the material allowed, have arranged the various forms round it according _to their assumed phylogenetic connection therewith. For ourselves, our material has been too small and our knowledge too limited to enable us to attempt anything so extensive. Nor must we forget to draw attention to their comprehensive scheme for separating the various forms, but their reasons for Changing the well-known term aberration to individual variety and variety to subspecies appear to us altogether unconvincing. To assume that, because ignorant and careless lepidopterists make an erroneous use of existing terminology, reason is shown for changing the terminology, appears to us unwarrantable. In our more ignorant days we misused the terms variety and aberration, over and over again, and main tained this misuse throughout the whole of our work, Tile Bn'tts/z [voctrcae and tlzeir Varieties, but to assume that a different terminology would have abolished our ignorance is at least open to question.
