...What a labour you have undertaken; I do HONOUR your devoted zeal in the good cause of Natural Science. Do you happen to have a SPARE copy of the Nomenclature rules published in the 'British Association Transactions?' if you have, and would give it to me, I should be truly obliged, for I grudge buying the volume for it. I have found the rules very useful, it is quite a comfort to have something to rest on in the turbulent ocean of nomenclature (and am accordingly grateful to you), though I find it very difficult to obey always. Here is a case (and I think it should have been noticed in the rules), Coronula, Cineras and Otion, are names adopted by Cuvier, Lamarck, Owen, and almost EVERY well-known writer, but I find that all three names were anticipated by a German: now I believe if I were to follow the strict rule of priority, more harm would be done than good, and more especially as I feel sure that the newly fished-up names would not be adopted. I have almost made up my mind to reject the rule of priority in this case; would you grudge the trouble to send me your opinion? I have been led of late to reflect much on the subject of naming, and I have come to a fixed opinion that the plan of the first describer's name, being appended for perpetuity to a species, had been the greatest curse to Natural History. Some months since, I wrote out the enclosed badly drawn-up paper, thinking that perhaps I would agitate the subject; but the fit has passed, and I do not suppose I ever shall; I send it you for the CHANCEof your caring to see my notions. I have been surprised to find in conversation that several naturalists were of nearly my way of thinking. Ifeel sure as long as species-mongers have their vanity tickled by seeing their own names appended to a species, because they miserably described it in two or three lines, we shall have the same VAST amount of bad work as at present, and which is enough to dishearten any man who is willing to work out any branch with care and time. I find every genus of Cirripedia has half-a-dozen names, and not one careful description of any one species in any one genus. I do not believe that this would have been the case if each man knew that the memory of his own name depended on his doing his work well, and not upon merely appending a name with a few wretched lines indicating only a few prominent external characters. But I will not weary you with any longer tirade. Read my paper or NOT, just as you like, and return it whenever you please.

Yours most sincerely, C. DARWIN.

HUGH STRICKLAND TO CHARLES DARWIN.

The Lodge, Tewkesbury, January 31st, 1849.

...I have next to notice your second objection--that retaining the name of the FIRST describer in perpetuum along with that of the species, is a premium on hasty and careless work. This is quite a different question from that of the law of priority itself, and it never occurred to me before, though it seems highly probable that the general recognition of that law may produce such a result. We must try to counteract this evil in some other way.

The object of appending the name of a man to the name of a species is not to gratify the vanity of the man, but to indicate more precisely the species. Sometimes two men will, by accident, give the same name (independently) to two species of the same genus. More frequently a later author will misapply the specific name of an older one. Thus the Helix putris of Montagu is not H. putris of Linnaeus, though Montague supposed it to be so. In such a case we cannot define the species by Helix putris alone, but must append the name of the author whom we quote. But when a species has never borne but one name (as Corvus frugilegus), and no other species of Corvus has borne the same name, it is, of course, unnecessary to add the author's name. Yet even here I like the form Corvus frugilegus, Linn., as it reminds us that this is one of the old species, long known, and to be found in the 'Systema Naturae,' etc. I fear, therefore, that (at least until our nomenclature is more definitely settled) it will be impossible to indicate species with scientific accuracy, without adding the name of their first author. You may, indeed, do it as you propose, by saying in Lam. An. Invert., etc., but then this would be incompatible with the law of priority, for where Lamarck has violated that low, one cannot adopt his name. It is, nevertheless, highly conducive to accurate indication to append to the (oldest) specific name ONE good reference to a standard work, especially to a FIGURE, with an accompanying synonym if necessary. This method may be cumbrous, but cumbrousness is a far less evil than uncertainty.

It, moreover, seems hardly possible to carry out the PRIORITY principle, without the historical aid afforded by appending the author's name to the specific one. If I, a PRIORITY MAN, called a species C.D., it implies that C.D. is the oldest name that I know of; but in order that you and others may judge of the propriety of that name, you must ascertain when, and by whom, the name was first coined. Now, if to the specific name C.D., Iappend the name A.B., of its first describer, I at once furnish you with the clue to the dates when, and the book in which, this description was given, and I thus assist you in determining whether C.D. be really the oldest, and therefore the correct, designation.
