Concerning the distinctness of this species from Q. oxyptera we 

 have already spoken (P. Z. S. 18G7, p. 990).

This Duck is not a Fulic/ula, as Burmeister has already shown. 

 Nor can it be placed with Anas, as it has a large bulbous expansion 

 in the windpipe, besides the curious bulging forehead. We have 

 therefore adopted for it a generic name invented by the late Prince 

 Bonaparte (C. R. xliii. p. 649).

A single young specimen. Not mentioned by Burmeister, unless 

 it be the P. bicornis, Licht., whicli we are not at present able to as- 

 certain with certainty.

7. Notice of Clymene similis, a New Dolphin sent from the 

 Cape by Mr. Layard. By Dr. J. E. Gray, F.R.S., 

 V.P.Z.S., F.L.S., &c. 



Mr. Edgar Layard has sent from the Cape the skull of a Dolphin 

 with the under jaw, which is so like the skull I figured under the 

 name of Delphinus obscurus in the ' Zoology of the Erebus and 

 Terror,' t. 16, that I at first regarded it as the same. But having 

 occasion to recompare it to identify the skull of a very young Dol- 

 phin that Mr. Layard has since sent from the Cape, I was interested 

 in finding that it showed the same kind of difference in the form of 

 the hinder part of the palate in front of the internal nostrils that I 

 have before observed in some true Dolphins which had very similar 

 skulls in other respects, but which belong to Dolphins very differ- 

 ently coloured, which were obtained in distinct parts of the world. 



In this case the two skulls both come from animals found at the 

 Cape ; but several Dolphins inhabit the seas surrounding that pro- 

 montory. 



1 have thought it desirable to distinguish the two skulls by dif-
