Pelvic Bones. — The one pelvic bone sent with the skeleton is very light and spongy 

 in texture, and is apparently not completely ossified at the extremities. Its length is 

 5"8 inches, and its greatest thickness 0'9 inch ; it is thus small in relation to the 

 general size of the skeleton, and would indicate that the animal was a female, if the 

 same sexual proportions obtain in Berardius as in many other Cetaceans. It is of very 

 simple form, subcylindrical, a little compressed, and with a shght bend at one third 

 of the length from one end, causing a low obtuse angular prominence on one edge. 

 The characters and dimensions of the bone would probably have been somewhat 

 different if the age of the animal had been more advanced. 



Conclusion. — The special osteological characteristics of Berardius will be more fully 

 appreciated when our knowledge of the skeletons of the other Ziphioids, especially of 

 the genera Mesoplodon and Ziphius, is more perfect. We can hardly go wrong, 

 however, in affirming that, as far as the structure of the skeleton is concerned, 

 Berardius is a peculiar form of the group, and that it occupies one end of the series 

 of which Hyperoodon forms the other, the remaining Ziphioids being in a certain
