Nor can it be placed with Anas, as it has a large bulbous expansion in the windpipe, besides the curious bulging forehead. W e have therefore adopted for it a generic name invented by the late Prince Bonaparte (C. R. xliii. p. 649). 94. LARUS CIRRHOCEPHALUS (Vieill.) (ex Azara, No. 410).

But having occasion to recompare it to identify the skull of a very young Dolphin 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 differently 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 promontory. I have thought it desirable to distinguish the two skulls by dif- |
