A on the subject of species names, one which I believe Cantino et al. should perhaps have addressed more directly, one way to look at the "problem" of species names is to look at it as a problem of GENUS names. Every species name includes (let's all repeat after me) four parts: generic epithet, species epither, author, and year of publication. In *most* cases, the (lower case) species epithet+author+year triplet is sufficient to unambiguously identify the entity in question. In situations where it is not, adding a letter to the end of the year, approximating the order of publication as closely as possible, can be added when the names are registered. This provides for maximum commonality with current practice, as it only violates one principle of Linnean taxonomy, that of obligate binomials, and it only adds one element, and then only in extreme cases. It also avoids hyphens, dots, dashs, squiggles, @ signs, and all other detritus of the computer age, which said symbols WILL prevent conventional systematists from taking our work seriously. As far as I am concerned, this is the simplest, safest, most reasonable way to handle the species-name question: as a virtual non-issue. However, what to do with genera? This rank has been polluted to no end (as has, to a lesser extend, the family) by it obligatory nature. Some neontologists may not be aware of the RAMPANT proliferation of monotypic genera among fossil groups. Indeed, it seems that some feel a new dinosaur species (for example) is not valid unless it has a new genus name (and, in the case of theropod dinosaurs and traditional systematists, often a new species). This, coupled with the constant threat of paraphyletic genera, has lead to a profusion of genus names, many of whcih are difficult to deal with. I have taken the preemptory tack of excessive lumping, combining genera which have been recognized as distinct for often nearly a century, but which are clearly and unequivocally sister groups. In dinosaurs, where subtle morphological variation is outwitted by even subtler taxonomic distinction, it is relatively easy to do this. However, sooner or later, we will have to decide what to do with all these names. I am with the interpretation above: they should be free for use jsut as any other clade name, but with the strong recommendation that they be very conservatively defined (i.e., with many specifiers). However, obviously, my opinion is not the only one under consideration. Many of the alternative naming schemes proposed in the Cantino et al. paper require that genus names not be available for naming as clades. As such, I am afraid I must propose another addendum, which I shall send along shortly. Jonathan R. Wagner -------------------------------------------------------------------------------- Jonathan R.
