The Annals and magazine of natural history; zoology, botany, and geology . e. o^ ^- «^^«*^« (Gray). I also procured lately an adult male and female and youngof the P. niger of Gould from Yea, in this colony. The femaleand young were quite black; and the skulls of each of themshowed a small semicircular lobe projecting outwards fromabout tlie anterior third of each outer margin of the nasalbones (not to be confounded with the more posterior wide an-gulation produced by the double concave curvature of the outermargins of P. setosus); so that, taken with the difference ofcolour, I at first thought it possible the species might be reallydistinct from the P. platyrhimis. But on carefully comparingall the bones of the skeleton, I could find no other difference;and on getting the skeleton of the male specimen prepared, Ifound that its skull agreed with the ordinary ty]3e of the P.platyrhinus in its nasal bones, although the individual was themate of the female referred to. The colour was not so perfecta black as in the female and young, but had a brownish tinge;. Dr. C. Colliugwood on Gigantic Sea-Anemones. 31 so that the skull, skeleton, and external characters of the furshowed P. niger to be only a variety of P. jylatyrhinus^ asDr. Murie has already correctly surmised would be found tobe the case. I finally have just had a typical brown ordinaryP. platyrhinus prepared for the Melbourne Museum, and havefound in it the small lateral lobes on the outer margin of theanterior third of the nasals, which I first noticed in the so-called P. niger^ and of which there was no trace in five skullspreviously prepared ; so that there can no longer be the leastdoubt of the black and brown individuals being only varietiesof one species. With the P. setosus^ we have thus four well-marked living wombats, and at least two fossil extinct ones. While referring to Dr. Muries paper above quoted, I maytake the opportunity to remark, in reply to his observationthat, in my description of P. la
