Length, 9 feet. The lower jaw is narrow in front, gradually becoming 

 wider behind, and with a distinct gonyx at the end of the symphysis. 

 The lower jaws of the two Ziphioid whales figured by Dr. Hector have onlv 

 a tooth at the front end, instead of a tooth at the front and one a little 

 further behind on the side of the jaw, as is usual in Berardius. Perhaps 

 this depends on age. The having only two teeth quite in front of the 

 lower jaw is the chai'acter of Epiodon, but that has a sub-cylindrical 

 tooth, and Dr. Hector's animals both have compressed triangular teeth 

 like Berardius, as figured in his plates, so that if they are not Berardius 

 they are a new genus. 

 Mesopilodon longirostris, of Krefft, of a skeleton of which in the Australian 

 Museum of Sydney he sent me a very beautifid photograph, appears to 

 be either Berardius hectorii or a new species. The photograph does not 

 show any teeth. The beak of the Australian specimen appears to 

 be longer, viz., nearly twice as long as the head, whereas the beak figured 

 by Hector is but little more than one-and-a-half times as long as the head.
