In all these forms, how-ever, the greater sublingual duct is intermediate between the submax-illary duct and the lesser sublingual glands. The variant Chimpanzee above figured and describedpresents the only instancein the primate series ex-amined in which the regulartopographical order of thethree intermandibular glan-dular components appearschanged and in which thegreater sublingual gland oc-cupies the lateral position,its duct crossing lateromesadthe cephalic margin of theintermediate lesser subun-gual group to its point ofunion with the main sub-maxillary duct.
