Types in taxonomy are coming up for discussion. There are at least 240 names of different sorts of types, without taking words in another side of biology and in printing into account. Of these some number being synonyms or homonyms will be given up. Statements or outlines of such special names of types have been changed frequently by later writers. To make simpler the words used in J. R Z. N. are only offered and if needed a short account on the special quality of that type may be given. The simple word “type” will do enough in all cases, for example, it is clearly pointing type species when it is used respecting a genus. Holotype and paratype are the necessary words, while topotype, hypotype, lectotype and neotype may be used sometimes as well.
