characters ; still, in his Catalogue of Marsupials he had to write 

 against the species — " Skull unknown." That this remark may 

 be no longer applicable, is the object of the present paper. 

 Although I have only one skull at my disposal, and that damaged, 

 the mutilation is not of such a character as to interfere with 

 features necessary for comparative purposes. 



Description. — Skull stout and heavy, sides of muzzle slightly 

 convex. Nasals somewhat expanded behind, their lateral edges 

 concave, narrowest in the middle, posterior suture forming an 

 obtuse backwardly directed angle. Ascending processes of pre- 

 maxillae greatly and suddenly broadened above, otherwise the pre- 

 maxillo-maxillary suture not greatly inclined. Naso-premaxillary 

 somewhat less than the nasomaxillary suture. Frontal region 

 narrow, immensely swollen, the supraorbital edges sharp and well 

 defined ; they are coincident with the fronto-parietal sutures, 

 coalescing where joined by the median frontal suture, thence 

 forming a single prominent sagittal crest to the interparietal. 

 Intertemporal area narrow, little more than the narrowest breadth 

 of the nasals combined, and equal to their anterior breadth. 

 Posterior palate without vacuities. In consequence of the inter- 

 parietal and occipital bones having been removed, their condition, 

 and also that of the foramen magnum cannot be described. 



Teeth. — The peculiarities already recorded are generally borne 

 out by this example, P descends much below 1 2 and P ; the 

 two latter are equal in length, P being much the broader. The 

 canine is about three-quarters the length of the smaller incisors 

 and proportionately strong. The premolar has no external ledge 

 and the posterior ridge is deeply notched. The molars are perhaps
