giilac, 80 miles S.W. of Melbourne, exhibiting the upper great 

 compressed carnassial and small tubercular molar in situ, but 

 wanting all the part of the skull anterior to these. A few months 

 ago the same Mr. Adeney brought to me the specimen figured in 

 the upper part of our plate from the same spot, and so entirely 

 completing the anterior part of the skull and teeth absent in the 

 skull he found nearly thirty years ago and sent to Professor Owen, 

 that he supposed it might have belonged to the same individual. 

 He also gave me the portion of the lower jaw found with it, figured 

 at bottom of our plate, and no doubt of the same creature ; the 

 corresponding portion of lower jaw in Professor Owen's above 

 quoted paper having been illustrated from a cast of a New South 

 Wales example, possibly of a different species. lu the Phil. Trans, 

 for 1866, Professor Owen published a second Memoir on Thyla- 

 coleo carnifex fi'om New South Wales specimens, of lower jaw and 

 a skull nearly perfect from occiput to front of mouth, containing 

 the sockets of the three anterior teeth on each side ; and finally, 

 in the Phil. Trans, for 1871, is. a third Memoir, completing his 

 illustrations of the subject from New South Wales specimens of 

 lower jaw and part of upper jaw, having only the second and third 

 teeth al)sent from the sockets, but describing and figuring these 

 latter from loose teeth. Our present specimen is therefoi'e the only 

 one as yet made known exhibiting all the teeth in front of the car- 

 nassial in the upper jaw in silu ; and as the Victorian animal is 

 the first descrilied type of the species, and I find it now to present 

 so many important differences from the New South Wales examples 

 described in Professor Owen's second and third Memoirs, it is 

 probable the species of the two colonies are really distinct. If so, 

 the Victorian one should bear the name of Tlnjlacoleo carnifex 

 (Ow.), and I wovild propose the name of T. Oweni for the subse- 

 quently illustrated New South Wales species. 



The first point which our specimen establishes is that the third 

 tooth from the front has its longer convex margin behind, and not 

 before as Professor Owen suggested fi-om the loose teeth ; and 

 this reversal of position brings its cutting edge into close sequence 

 with the second tooth, so as to resemble one of the ordinary group 

 of three incisors with the more anterior ones, and turned away
