STRANDED AT LONGNIDDRY. 201 



a huge lateral bulging, giving a greater girth than when it first came 

 ashore. Close to the posterior ends of the mesial abdominal plicae was a deeply 

 puckered scar, the umbilicus. 



The nipper projected from the side of the body 31 feet 4 inches behind the 

 tip of the lower jaw, measured in a straight line, and 14 feet behind the angle 

 of the mouth. It curved outwards and backwards, terminating in a free pointed 

 end. Its surfaces were flattened ; its anterior border rounded and convex from 

 root to tip, measured 12 feet 3 inches ; its posterior border concave from root 

 to tip 10 feet, whilst its girth at the root was 9 feet 6 inches. The distance 

 between the two flippers, measured over the back, between the anterior borders 

 of their roots, was 18 feet 6 inches. 



The slit-like entrance to the female passage was situated 22 feet in front of 

 the fork of the tail. Its antero-posterior diameter was 16 inches. It was 

 bounded laterally by elongated prominent folds of the integument, which 

 represented the labia majora, and were indented by longitudinal furrows. 

 In front of the aperture was a rounded elevation representing the mons, 

 which was placed 10 feet behind the longitudinal plicae on the middle of the 

 belly. Behind the mons was a deeply depressed part of the integument, 

 immediately posterior to which was a thick clitoris, triangular in its outline. 

 Its length was 6 inches, the breadth at the root 4 inches (Plate VI. fig. 6). The 

 clitoris curved backwards, and overlapped the external orifice of the urethra, 

 which orifice was surrounded by a well-marked fold of mucous membrane. 

 Both on its superficial and deep aspects it presented a rugose appearance. 

 On each side of the root of the clitoris a projecting fold lying between the 

 labia majora passed backwards, external to the urinary meatus. These two 

 folds formed the labia minora ; they bounded the vestibule, and their inner 

 surfaces, as well as the floor of the vestibule, possessed a number of complex 

 ridge-like elevations of the mucous membrane. When this membrane was cut 

 through, a quantity of erectile tissue, in which were many large veins, was 

 seen. Eight inches on each side of the female passage was a funnel-shaped 

 elevation of the integument, at the summit of which a circular aperture, which 

 readily admitted the tips of the fingers into a fossa about 4 inches deep, was 

 seen. Projecting from the bottom of this fossa, but not through the circular 

 aperture at its summit, was a large nipple about 3 inches long, which possessed 

 an orifice at its free end — the termination of the great lacteal duct — into which 

 the forefinger could be passed. A number of pedunculated papillae were situated 

 at the summit of the nipple around this orifice (fig. 7). 



Thirteen inches behind the female passage was the orifice of the anus, 

 which was small and contracted, but could easily be dilated so as to admit 

 the hand. The integument immediately around the orifice was rugose, and in 

 the neighbourhood both of the intestinal and genital openings the skin was
