Dr. J. E, Gray oti ZlpMoid Whales. 19 



I also observe that Duvernoy gave the name of " Hyferoodon 

 GervaisiV and Fischer's '■'• ZipMus GervaisiV to the skull 

 in the Paris Museum, from the Herault, which I proposed, in 

 the 'Annals,' 1872, x. p. 469, should be called Ejnodon 

 Heraultii^ but which I gladly change to that of Epiodon Ger- 

 vaisii. I see Professor Flower erroneously refers to ' Osteogr. 

 C^t.' t. 21. f. 1-6 for this specimen ; it should be f. 1-4. 



Mr. Krefft, some time ago, sent me a photograph of the 

 skeleton of a ziphioid whale which is in the Museum of 

 Sydney, and was obtained from an animal stranded in Little 

 Bay, about six miles from Sydney, which he marked as 

 Mesoplodon longirostris^ Kreffi. It appears to be, from the 

 scale appended, 18 feet long. The angle and symphysis of 

 the lower jaw appears to be rather elongate and attenuated in 

 front ; and the beak is about twice and a half the length of the 

 brain-cavity, measuring from the notch ; and the head is one 

 fiftli of the entire length. The photograph does not show any 

 teeth ; and the skull resembles that of the figure of Berardius 

 Hectori ; but the beak is rather longer in proportion to the size 

 of the head. 



In the ' Annals and Magazine of Natural History, 1871,' vii. 

 p. 368, 1 published a note which I had received and the figure 

 from the photograph of a tooth which Mr. Krefft sent to me, 

 as " the photograph of the tooth of a new whale, 18 feet long, 

 caught in Little Bay. It is allied to the genus Mesoplodon ; 

 and I propose to call it Mesoidodon GilntlieriP He says, 

 " We have the entire skeleton ; " so that there can be no doubt 

 of its being the same as the one he named, but did not describe 

 or publish, as Mesoplodon longirostris^ which Professor Flower 

 thinks is closely allied to, if not identical with, Ziphius Lay- 

 ardi. The form and surface of the tooth which is figured 

 from Mr. Krefft's photograph appeared to me so unlike that 

 of any other ziphioid whale known that I regarded it as in- 

 dicating a new genus, which I proposed to call Gallidon. 



Dr. Krefft explains that the tooth is not visible from with- 

 out ; it is imbedded in the mandible, and the tip is bent 

 towards the margin. It is as unlike the strap-shaped tooth of 

 Ziphius Layardi as it is possible to be ; and as longirostris has 

 not been published, I propose to call it Gallidon Gilntheri. 



The skeleton seems, from the photograph, to be one of the 

 most perfect known.
