The grounds forregarding this element as intermechate between the parotid and theorbital series have already been stated, from which it follows thatthe glands opening upon the stomal ridge are to be regarded phyleti-call) as a single series, secondarily divided in mammals by the suppres-sion of its intermediate portion, of which the variable orbitoparotidis representative. The modifying factor is the masseter, in relationto which the series resolves itself into an ectomasseteric element, the. Fig. 19. Schema of the salivary glands in fissipede carnivores. The constantelements are shown solid, the variants in outline. parotid, entomasseteric elements, the orbital series, and promassetericelements, orbitoparotids. The last, when well developed, tend toescape from their confinement along the border of the masseter, following the line taken by the parotid sprout; they may retain theintramuscular position (Procyon) or acquire a position on the lateralsurface of the muscle near its ventral border (Gulo). The diagram (Fig. 19) is intended to express graphically theseconclusions as to the composition of the hssipede carnivore salivarycomplex.
