Feb. 1856. I went over this list with Waterhouse & compared it with Jekel, (who has gone only a very little way in his version) & the 2 first genera, on which we came were greatly enlarged, & the species said to come from other & distant countries really formed distinct genera. [Schölen] used very artificial character. Waterhouse doubts whether many wd stand the test - Genus 350 Cape & Brazil only 2 species seem true & these species are very closely allied.
(Waterhouse knew only a few of these genera, & my astonishment that he had picked out these small wide-ranging genera in his list of anomalous genera really goes for nothing.) Hence we may conclude far most genera are confined to one country.
