Just remember that the second part of the name, the species name, does not have a capital letter.
'pratensis', here, is Latin for 'of the meadow'. It is the part of the name that should differentiate it from others of the same genus. For example Anthus trivialis, the Tree Pipit is the Anthus 'of the crossroads' (trivialis), Anthus petrosus is the Anthus 'of the rocks' (petrosus)...etc.
