For both these causes of variation,full allowance must be made—as well as for thevariation of colour at different stages of distension,which has been already alluded to. It is hoped that the following descriptions maysuffice to identify the species in all its stages. Ixodes redu-iiiiis Linnaeus = /. riiiniis d.
