DR. J. MURIE ON THE ORGANIZATION 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 own 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 sterno- 
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. I found its vessel all but closed; but in the younger 
Craigie’s-Bridge specimen it was “ pervious, opening freely into the vena porte.” 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-reservoir; 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 ruge within.
