Page 10 - If an author, in publishing a genus with more than one valid species, fails to designate (see a) or to indicate (see 6, d) its type, any subsequent author may select the type, and such designation is not subject to change. (Type by subsequent designation.) The meaning of the expression "select the type
Page 10 - Linnean genera, select as type the most common or the medicinal species (Linnean rule, 1751) ; (i) if a genus, without designated type, contains among its original species one possessing as a specific or subspecific name, either as valid name or synonym, a name which is virtually the same as the generic name, or of the same origin or same meaning, preference should be shown to that species in designating the type, unless such preference is strongly contraindicated by other factors (type by virtual...
Page 15 - When a genus is subdivided into other genera, the original name should be retained for that portion of it which exhibits in the greatest degree its essential characters as at first defined. Authors frequently indicate this by selecting some one species as a fixed point of reference, which they term the
Page 35 - When they omit doing so, it may still in many cases be correctly inferred that the first species mentioned on their list, if found accurately to agree with their definition, was regarded by them as the type. A specific name, or its synonyms, will also often serve to point out the particular species which by implication must be regarded as the original type of a genus. In such cases we are justified in restoring the name of the old genus to its typical signification, even when later authors have done...

If no species was designated, the type is the first binomial species in order eligible under the following provisions : (a) The type is to be selected from a subgenus, section or other list of species originally designated as typical...
Page 10 - When in the original publication of a genus, one of the species is definitely designated as type, this species shall be accepted as type, regardless of any other considerations. (Type by original designation...
Page 15 - Now in zoology no one person can subsequently claim an authority equal to that possessed by the person who is the first to define a new genus or describe a new species ; and hence it is that the name originally given, even though it may be inferior in point of elegance or expressiveness to those subsequently proposed, ought as a general principle to be permanently retained.
Page 16 - ... distinguished by the above titles. [No special rule is required for the cases in which the later of two generic names is so defined as to be less extensive in signification than the earlier, for if the later includes the type of the earlier genus, it would be...
Page 15 - Lawrence, or Harvey, that they were devoid of meaning, and should hence propose to change them for more characteristic appellations, they would not act more unphilosophically or inconsiderately than they do in the case before us ; for, in truth, it matters not in the least by what conventional sound we agree to designate an individual object, provided the sign to be employed be stamped with such an authority as will suffice to make it pass current.
