164 ANATOMY OF THE SALIVARY GLANDS IN THE CARNIVOR.\ 



branches have been found in embryos of the cat (Schulte) one of 25 

 millimeters, one of 31 milUmeters. Both ascended from the border of 

 the muscle, with a moderate caudal inclination, and joined the main 

 duct close to its bifurcation (Part VI, page 246). 



The orbitoparotid (Fig. 5, 5) is a minute element, not exceeding 

 2 millimeters in diameter and 3-4 millimeters in length in any of our 



specimens. It is 

 interposed between 

 the parotid duct 

 and the oral epi- 

 theUum, in the 

 space between the 

 deep and superficial 

 facial veins mesad 

 and laterad, and 

 the border of the 

 masseter caudad, 

 to which its fundus 

 isapphed. Itspos-- 

 sibihties of growth 

 are thus confined 

 within narrow

 laterad and ventrad along the sloping border of the masseter is there 

 space for expansion, and this is somewhat infringed upon by the super- 

 ficial facial vein. The duct opens either into that of the parotid close 

 to its orifice, or upon the stomal ridge midway between that of the 

 parotid and that of the first orbital gland (Fig. 2.8). This element 

 was present six times in our five cats. 



The orbital series is composed of six or eight glands diminishing
