Volume two arrived on thursday..sorry folks forget a lot of what you knew about ungulates!Using the taxonomic revisions of Colin Groves[and providing much mitochondrial or morphological evidence] the Bovidae [antelopes,cattle,sheep,goats.duikers etc]have increased by almost one hundred species!Hippos are included but are now thought to be more closely related to cetaceans than ungulates,the Musk Deer is not really a deer,there are 11 species of Klipspringer,6 of Chamois,12 Dik-diks,5 Gnus,18 of Hartebeest -I could go on and on.Of course this involves a rather different view of speciation and one which i feel will be generally accepted before long.Suffice it to say that it makes most of my ungulate library look rather dated.
