narrowing by degrees to the meatus urinarius, which opens at the deep surface of the 
clitoris. 
The female external generative aperture in Glodiceps, as in all true Cetaceans, is an 
elliptical fissure or median sulcus situate at the hinder end of the body, where com- 
mences the caudal narrowing, or near the middle of the third fourth of the animal’s 
length, and inferiorly about vertical to the termination of the panniculus. The 
tegument around is dark-coloured, and thrown into a good number of minute parallel 
and wavy wrinklings chiefly transverse in direction. The opening of the vulva is 
33 inches long, and it is less than a third of that across at its widest part. The anal 
orifice, not over half an inch in diameter, is distant 2°7 inches behind the posterior 
pudendal commissure. Immediately within each lip of the vulva, or what may be con- 
sidered the labia majora, are some twenty or more short, but deep, folds of membrane, 
in the recesses of which are crypts, the openings of sebaceous glands. The homologues 
of nymphe or labia minora are two prominent folds of the mucous membrane, each an 
inch in length, which lie within the anterior pudendal commissure, and slightly converge 
as they pass backwards. Between these and with lateral plicate sulci is a median ridge 
1:3 inch long, which ends in a small but distinctly pronounced conical-shaped clitoris. 
The vagina, 9 inches in length, whose mouth is about the middle of the external 
uro-genital fissure, sweeps diagonally towards the abdominal cavity. In the two latter 
points, as in the uterus entire, Globiceps agrees pretty well with the Whale type as 
described by John Hunter and others in specific forms. The lower vaginal half is 
widish and smooth, or with only fine longitudinal plications; the upper half, on the 
contrary, is narrower, and has a very uneven surface. This roughening depends on a 
numerous series of transverse rug or puckerings of the membrane, some four of which 
are extremely prominent. In alluding to these valvular folds, Hunter aptly compares 
them to a succession of ores tincarum. ‘They are composed of thick induplications of 
the fibroid tissue of the wall of the vagina (fig. 74), inwardly lined by narrow longitudinal 
mucous rug, which fringe their free edges. The fold nearest to the os, and only a 
good thumb’s breadth from it, has a thickness of ‘6 of an inch. ‘The true os uteri is 
only distinguishable from the preceding folds by its narrower and somewhat firmer 
ring-like aperture. The cavity of the uterus above in this specimen is only 2 inches in 
length, and then divides into right and left cornua. There is a circular membranous 
fold about half an inch above the os; but the mucous coat of uterus and cornua is 
longitudinal and wavy. The broad ligament and the fimbriz of the Fallopian tubes 
form a delicate arched covering or pavilion which overarches the ovary. Each 
narrow oblong ovarian body is about two inches in extreme diameter, and is of firm 
consistence. 
The mammary glands, as might be expected in a young animal, were but of moderate 
size, namely, about 4 inches long, and their glandular structure in consequence feebly 
developed. These organs, as in other Cetacea, lie upon each side of the vulva, and
