parts. Where black, much of the pigraent could be removed by 

 washing, and frora the inner surface was readily communicated to 

 the fingers. 



The true blubber on the back and sides measured on an average 

 2 inches in thickness. On the throat where the plicse occurred, it 

 became tendmous and tough, and, though removed, was not expected 

 to yield much oil. 



The whole posterior part of the body was beset by strong round 

 tendons, about an inch thick, originating as flat tendons within the 

 museles above the pectorals. 



The extent and direction of the plicce on the throat and abdomeu 

 are shown in the drawings of the animal. PI. XLV. fig. 8, represents 

 sections of the stretched and unstretched surface of the plicce. At 

 those portions of the throat and belly which required more capability 

 of distention than the ręst, farrows supplementary to the general ar- 

 rangement of the plicce were introduced. These however invariably 

 disappeared ere they reached the termination of the regular plicce, 

 and were insertedunsymmetrically. The furrows continued of their 

 full depth to their termination on the abdomen. 



Where the body of the animal was black, the furrows and their in- 

 terspaces were black also, being there covered with skin of the šame 

 texture as that of the body. Where the black of the body began to 

 wash offmto the white of the lower parts, the furrows were black 

 and the interspaces pure white. On the lovver surface, again, where 

 the sole apparent colour was white, the plicce were found on separa- 

 tion to be lined with a rosy, longitudinally striated, transversely 

 wrinkled epidermis. The depth of the furrows varied escessively, 

 being, in some parts, when the pouch was undistended, nearly 

 \\ inches deep, while on the jaws and between the eye and pectoral, 

 they were so shallow as hardly to bear measurement at all. \Vhen 

 the pouch was distended, the plicse were partially obliterated, their 

 hollows becoming nearly as high as the surface of their highest pro- 

 minences. 



The normai breadth of the interspaces between the furrows was 

 about 2 inches. Near the chin, however, in some places three or 

 four occurred in the space of an inch, the skin being there very soft 

 and pliant. The ridge between the two furrows which passed mesially 

 along the throat and abdomen was broader than the ręst, the furrows 

 diverging slightly towards their posterior tennination, vvhere the 

 scarcely perceptible umbilicus was situated, thereafter converging as 

 shown in the figure. 



The reproductory organs were situated 4 feet behind the termina- 

 tion of the plicce, and immediately between the slits into which the 

 mammce were retracted. The mammce were of a yellowish flesh- 

 colour, 1 1 inches long and 4 inches in diameter, ending in lax nipples 

 2 inches in diameter. 



The uterus extended in the body of the Whale 5 feet forwards 

 from the opening. It did not contain a foetus. The anus was 

 2 feet 1 inches behind the anterior commissure of the reproductory 

 organ.
