SCHULTE, SEI WHALE. 463 



Near its caudal extremity a very short band connects the caudal pole of the ovary to the uterine 

 cornu, opposite the point at which the ligamentum teres begins. For this reason I take it to 

 be the ligamentum ovarii. Daudt in his larger foetus describes this fold as passing from the 

 junction of the middle and last thirds of the ovary to the cornu, so that it appears to shift rostrad 

 during development. The short transverse fold, which he describes as passing from ovary to 

 oviduct between this ligament and the ovarian attachment of the ostium abdominale, is not yet 

 indicated. The plica diaphragmatica is long and high. It attaches to a convolution of the 

 oviduct close to the ovary and extends lateral to the kidney somewhat beyond its rostral pole. 



Oviduct. The infundibulum is long and slit-like with even margins, forming a flattened 

 funnel, the rostral extremity of which is attached to the ovary. Its interior is at first smooth, 

 but in its depth becomes marked by small folds and furrows, which converge towards the ampulla. 

 The oviduct is closely convoluted, its turns obscured by their peritoneum. Of these there seems 

 to be four on each side. As a whole the tube has a general sagittal course on the lateral aspect 

 of the ovary and terminates by turning mesad and ventrad to join the uterine cornu. To its 

 commencement is attached the plica diaphragmatica already mentioned. 



Uterus. The uterus consists of a short body and long arched cornua, which turning laterad 

 upon the ventral surfaces of the ovaries diminish rather abruptly in diameter and are continued 

 as the oviducts. Ectally this junction is marked by a change in direction, the proximal segment 

 of the oviduct forming a small angular bend below the ostium abdominale, just mesad of which 

 it enlarges to become the cornu. Distad the cornua are in contact for about a third, of their 

 length before they unite to form the body of the uterus. This junction is perfectly symmetrical 

 in external view. The cornua have a length of 17 mm. measured along their convexity; their 

 diameter is 3 mm. The body of the uterus is short measuring from the union of its cornua to the 

 first transverse sulcus of the vagina only 6 mm. Its form resembles that of an hour-glass, 

 diminishing to about its middle and again expanding towards the vagina. Ventrally it is some- 

 what flattened against the bladder, but dorsally it is strongly convex. The cornua and broad liga- 

 ment also rest against the convex dorsum of the bladder, and curve ventrad upon its sides so 

 that the terminations of the horns rest against the hypogastric arteries. Here there is a slight 

 degree of asymmetry, for the axis of the uterus deviates from the midline to the left as it is fol- 

 lowed rostrad and in consequence the left cornu is at its termination slightly caudal to the right. 

 The same holds true of the ovary. The difference between the two sides is however so small 

 that it may well be dependent upon the curvature of the foetus. 



Internally the uterus is not more clearly demarcated from the vagina than externally. Fol- 

 lowing Daudt I take the first of the transverse folds as the boundary. Here also the character 

 of the surface begins to change. The surface of the fold is faintly crenate and the sulci extend 

 a little beyond it, but soon fade out and the mucosa of the uterus becomes smooth. Not even 

 with the binocular could I detect traces of the longitudinal folds of later stages either in the 

 body of the uterus or in the cornua. From the point of union of the cornua a septum extends 

 a short distance into the body, but ends before its constricted middle region is reached. There 

 was no asymmetry internally in the union of the cornua, such as Daudt records of his foetus. 



Ligamentum latum. The broad ligament, as has been said, is concave ventrally. As it 

 nears the lateral walls of the abdomen it becomes bent upon itself dorsad along a line running 

 from the arch of the hypogastric artery to the proximal convolution of the oviduct. Beyond 

 this line the ligament is directed dorsad as well as laterad gaining attachment to the parietes
