174 ANATOMY OF THE SALIVARY GLANDS IN THE CARNIVORA 



inferior alveobuccal glands (i6) are of moderate development. The 

 caudal end of the series is near the angulus oris ; the cranial does not 

 quite reach the diastemal fold. 



The submaxillary (20) resembles that of Mephitis in its ovoid form 

 and vertical axis. The duct (2/) emerges a little below the dorsal pole, 

 ascends over the digastric muscle, and thence extends horizontally to 

 its orifice behind the symphysis. A small dorsal accessory lobule is pres- 

 ent, draining into the distal segment of the duct, and closely applied to 

 the dorsal pole of the gland. There are two submaxillary lymphnodes. 

 The greater sublingual gland (23) is smaller than in any of the forms 

 we have been considering, wholly ental to the digastric and supramylo- 

 hyoid in position. The body is ovoid ; the duct emerges from its cranial 

 pole ; small incrusting lobules about the duct are wholly lacking. 

 The lesser sublinguals {18) are of moderate development, extending 

 from the arcus palatinus to within a short distance of the frenulum. 



A second specimen of this animal (Columbia Morphological Museum, 

 No. 2153) presented important departures from the foregoing, espe- 

 cially in the conditions of the glands of the alveolingual region. The 

 submaxillary (Fig. 12, 20) was peculiar in the development of dorsal 

 accessory lobules, three of which were present. The largest occupied 

 the angle between the duct and the dorsal pole of the gland body ; 

 ectal to the digastric, it evidently corresponds to the smaller lobule 

 noted at this point in the preceding specimen. It drains by several 

 ductules into the main submaxillary duct. The second lobule is 

 placed at the cranial border of the digastric, separated by a small 

 interval from the one just described. It is ovoid and drained by a 

 single duct. The third and smallest rests against the hyoglossus 

 muscle. Its ductule, which is long and slender, is directed craniad and 

 ventrad to join the submaxillary duct near its point of intersection 

 with the lingual nerve. This is the greatest development of the sub- 

 maxillary complex I have met with in the carnivora, as regards the 

 size and number of accessory lobules. The lesser sublinguals (18) 

 are also a larger mass than in the other specimen, and extend from the 

 frenulum into the arcus palatinus, where they are continuous with 

 isthmian glands. They are best developed craniad, where they sur- 

 round the submaxillary duct on its dorsal and lateral aspects. The 

 caudal members of the series are smaller, forming a thin sheet from the
