|Title||Further revisional notes on the Belonidae|
In my recent revision of the Belonidae (Mees, 1962) a number of problems had to remain unsolved because of lack of material, and in particular because of a number of named forms the type specimens had not been available. The revision was called "preliminary" for that reason.
Thanks to the co-operation of colleagues in several countries I have been able, on a round-the-world tour which lasted from February to August, 1962, to examine nearly all the types of what I had previously had to regard as species dubiae, and other type specimens, which show that in a few instances the synonymy presented in my paper is erroneous. A serious error in the key also became obvious (see under Belone punctulata).
Though, inevitably, a few problems remain to be solved, it is now possible to give a reasonably exact count of the number of genera, species and subspecies in the family. I recognise two genera: Potamorrhaphis with one species, and Belone with 23 species and 5 subspecies. This compares with estimates of from sixty to a hundred species given in literature.
It is a pleasant duty to acknowledge the help from the colleagues who made it possible for me to examine so many type specimens: Dr. J. W.
