Figure 1 - Number of names. Total number of taxonomic names listed in Sherborn's Index Animalium and in AnimalBase (2011) plotted in 5-year intervals. It must be taken into account that Sherborn's numbers included a proportion of 30% of names that were not new, while in AnimalBase this proportion was much lower (less than 5 %).
