tissue on its mesal side close to the anterior pole of the ovary. In foetuses this lobe is 

 small in comparison with the ovary, but it becomes very large in adult whales. Beaure- 

 gard and Boulart described two further fatty masses, circular in outline, within the 

 ligamentum latum on either side of the vagina ; but these were not seen.

The oviduct and ovarian funnel 

 Rapp (1837) mentions that in Phocaena phocaena the ends of the Fallopian tubes are 

 "extraordinarily widened" and Turner (1870 b) said that in Orcinus the width of the 

 tuba mouth embraced the whole ovary. In Hyper oodon Weber (1886) found the tuba 

 mouth even more widened, and described the edges of the funnel converging to a tag 

 running on to the rostral pole of the ovary, as described for the Balaenoptera under 



review.
