nomen

[Lat.] A name; one of the three tetra-hydric-dioxi-dichloro-dinitride. The above names given to an ancient Roman, and denoting the gens to which he belonged. *no-měn-clā-tive, adj . [NOMENCLATOR.] Pertaining to naming or nomenclature; nomenclatory. no-měn-clă-tor, s. [Lat., from nomen a name, and calo to call; Fr. no men clat eur; Ital. nomen clatore.] 1. A person who calls persons or things by their names. 2. Specif . in Roman Antiq .: (See extract.) "When the population had increased to such an extent that it was impo ible for a candidate to know all the termed a nomenclator, whose sole busine it was to voters even by sight, he was accompanied by a slave become acquainted with the persons and circumstances of the whole constituency, and to whisper such in form a tion into his master's ear, when he pa ed from one to another in the crowd, as might enable him to salute each individual correctly by name, and to greet him as an acquaintance." -Ramsay: Roman Antiq. 3. A person who gives names to things, or who settles or determines the nomenclature of things in any branch of science or art. "Adam (God's nomenclator ) could not frame One that enough could signify." Cowley: Her Name. 4. A dictionary, lexicon, or vocabulary, espec, one dealing with scientific nomenclature. *5. (See extract.) rule does not apply strictly to organic substances, where regard is had to the history of the groups forming the compound. 4. Geol.: For the names given to the geological formations, as Silurian, Devonian, Oolite, . (see Geology). The system adopted has many merits, but in one direction it tends to generate error. When a stratum is called chalk, one naturally expects it to be white and calcareous; it may be neither the one nor the other. When another is called greensand, the mind expects it to be characterized by grains of sand of green color; it may be quite different. Such words, used of the spots where the several strata were first identified. are appropriate; but, being founded on local peculiarities, become quite inaccurate when applied to other, and specially to distant regions. Used of the world at large, they are simply chronological, and have no reference to the appearance of particular rocks. 5. Min., Petrol ., & Palæont .: Linnæus carried his system of two Latin names through the mineral no le than the animal kingdom. Thus, he had his Schist us tabular is , S. atratus , . These are now exchanged for the vernacular terms. Minerals are now generally made to end in -ite, which Dana alters for rocks to -yte. Genera of fo ils often end in ites, as Belemnites, anglicized Belemnite. 6. Zool .: In the days of Swains on and the other adherents of the quinary system, conformity of system in the nomenclature was greatly insisted upon. Every tribe ended in -es, every family in ide, and every sub-family in -ine. Of late, the system has been departed from, and the great aid which it rendered to the memory in consequence sacrificed. With regard to vernacular names, they vary in different parts of the country, and often sin, aş; expect, Xenophon, exist. ph = f. nomenclaturist suggest error. Thus the goat-sucker does not suck goats, and the titmouse is not one of the Muride, but a bird. They are regarded as unscientific, and used only for popular convenience in scientific works.
