DR. J. MUEIE ON THE OBGAOTZATION OF THE CAAING WHALE. 261 



have no salivary glands ; by others' that they are reduced to the most rudimental con- 

 dition, while a third set of observers^ evidently point to their presence as fairly deve- 

 loped. In my oven researches among the group, notably the toothed section, I have 

 satisfied myself that two of them obtain, and these not so feebly represented as I had 

 been led to imagine. Their position and relations in Globiocephalus, Grampus, and 

 Lagenorhynchus sufficiently agree for one description to serve. The parotid, firm and 

 thick, is situated behind the auditory canal and the small fleshy slip connected there- 

 with. It occupies, and somewhat deeply, the angle between the insertion of the stemo- 

 mastoid and cephalo-humeral and the anterior nuchal continuations of the long dorsal 

 muscles. Steno's duct, a fair-sized tube, passes forwards to the cheek. The sub- 

 maxillary gland is flatter and thinner, but with a superficies almost as large as the 

 parotid. It lies between, and partially overlaps, the neighbouring borders of the large 

 muscle representing the digastric and the masseter, inferior to the auditory tube and in 

 front of the cephalo-humeral muscle near its insertion. The facial artery and nerve 

 either partially pierce or lie closely adherent and beneath the upper margin of the 

 submaxillary gland. The cutaneous muscle covers both. 



The liver (fig. 34), in simplicity, agrees with that of other Cete ; but, as considered 

 divisible into a right and left lobe, these were nearly of equal size, and not with a pre- 

 ponderant right, as Dr. Jackson' found in his specimen, nor with a left enlargement, as 

 the same author describes in the Sperm-Whale. With an average diameter of 18 inches, 

 the organ is rather flat, smooth, and of medium thickness. There is no gall-bladder — as 

 all observers record, excepting Williams', who says in G. chinensis it is small. 



The round ligament is of considerable thickness, and dips into the anterior median 

 incision or umbilical fissure. 1 found its vessel all but closed; but in the younger 

 Craigie's-Bridge specimen it was " pervious, opening freely into the vena portse." The 

 broad ligament has a nearly mesial line of attachment, and is strong. The coronary 

 and the two lateral ligaments are fused together, and cover only the inferior edge of 

 the right moiety of the gland. 



The umbilical is the only well-marked fissure ; that for the vena cava is broad and 

 shallow ; and a mere central indentation marks a transverse fissure where the hepatic 

 and portal vessels enter. A single hepatic duct, half an inch in diameter, is joined by 

 the united double and much narrower pancreatic duct, about two inches from the liver. 

 Thence, three inches further on, it enters the serous coat of the duodenum and forms a 

 dilated bile-reservou" ; a narrow passage, five inches long, continues the duct within 

 the intestinal wall ; and it pierces the mucous coat nine inches distant from the pylorus. 

 The expanded portion of the duct has alone narrow transverse rugae within.
